Additional info on how to use SSL on tomcat can be found on the Apache/Tomcat website. Also refer to this article: How to solve javax.net ssl. SSLHandshakeException?

Currently you must not disable 's http port. In a future release this will be allowed. Disabling ' http port will cause your form server to malfunction as  requires this port. For most cases it is sufficient to share the https version of your form/flow's Url and leave http open. However, if you want to force all form usage to be over https and feel it is not enough to simply share the https form Urls (as a user can switch to http as long as that port is open), we recommend that you deploy  behind an Apache or IIS server. Close the http port on Apache or IIS but leave tomcat's http port open so that  can POST back to itself when needed over http but no one outside can access it.

Tomcat Logfiles

By default, the  server writes useful logging information to a daily logging file located here: <frevvo-home>/tomcat/logs/frevvo.log. You will see the logfiles listed below in <frevvo-home>/tomcat/logs. The current date appends to the logfile name for all the files except the frevvo log:

...

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="${catalina.base}/logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b &quot;%{Referer}r&quot; &quot;%{User-Agent}r&quot; [%I %{JSESSIONID}c]" />

...

" />

• host-manager.MM-DD.-YYYY.log - this logfile is part of the tomcat distribution and tomcat distribution and is empty by default - this . It is the a log file for the tomcat host-manager web application which that is used to check the status of web apps, memory usage etc. Messages manage virtual hosts in tomcat. The host manager web-app is typically not needed because  is preconfigured. Messages are written to this log only if the manager web app is being used. 

...

There will be three additional logfiles when running Tomcat as a Windows service:

...

• the host-manager web application is being used.
• manager.MM-DD.

Debugging logfile levels

The logging levels used by  can be fine-tuned by editing the <frevvo -home>/tomcat/lib/logback.xml file. By default  log level is set to INFO. The logging infrastructure will scan this file every 60 secs so you can live-change the log level. Here
is more configuration information .  Stop  to delete the logfiles. They will be recreated on start up.  

You can obtain more debugging information, if needed, by following the steps below to change the loglevel. You will see the results of the changes in  <frevvo-home>/tomcat/logs/frevvo.log.

If you are having issues running the server in an environment with proxy setups, load balancers etc. the forms.ui.filter logger can help. This logger will output additional information to the frevvo.log file to assist in determining what the frevvo servlet is seeing. To enable this logger uncomment the following line in logback.xml:

<logger name="com.forms.forms.ui.filter" level="DEBUG" />

Logfile Rotation

The  tomcat bundle install will automatically rotate log files daily. The logfile is the only one affected. Let's say the current date is 6 - 19 - 2013. The current days logging is saved to the frevvo.log file located in <frevvo-home>/tomcat/logs.  On the next day, 6 - 20 - 2013,  the log from the previous day is copied to a logfile stamped with the previous day's date. (frevvo_2013-06-19). This date stamped frevvo.log is moved into the <frevvo-home>\tomcat\logs\old directory. Logging for 6 - 20 - 2013 is saved in the frevvo.log in <frevvo-home>/tomcat/logs.

Session Timeout

's default web browser session timeout is 480 minutes. If a user is logged into the  server to design forms, or to view their task list, or is using a  form and filling in values but has not yet submitted the form, the session will expire after 480 minutes of inactivity. When the session expires the designer will have to re-login to  to continue designing forms and form users will have to get a new instance of the form and re-enter the values.

If the maximum number of concurrent users are logged in simultaneously, and any of them are idle for more than 480 minutes, the next person who tries to log in will be able to do so successfully.

The session timeout can be changed by editing <frevvo-home>\frevvo\tomcat\webapps\frevvo\WEB-INF\web.xml. The session timeout setting unit is minutes. For example, to change from an 480 minutes (8 hr) session timeout to a 1 hour timeout change 480 to 60.

<session-config>
    <session-timeout>480</session-timeout>
</session-config>

The default  server session timeout can be overridden for each tenant. See the Edit Tenant topic for more information.

When a session times out, for example when a person is using a form and then pauses for longer than the configured <session-timeout>, they will see the following error the next time they enter a value into the form.

Editing Submissions

Submissions can be edited via the Submissions Page. This feature is disabled by default for  in-house users. To enable this feature,  add the frevvo.submissions.edit.link configuration parameter to the <frevvo-home>/WEB-INF/web.xml.  For more
details on the feature that this parameter controls see Editing Submissions. The web.xml file must be unzipped from the frevvo.war before it can be edited. See above for the details. 

Hardware Requirements

The minimum recommended hardware configuration for your Live Forms server is:

• 2 gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor
• 4 gigabyte (GB) of system memory
• 100 GB hard drive

However you must size your hardware platform to your specific form usage characteristics. As the number of concurrent users and forms increases so must the system memory. For a medium use production server consider increasing the JVM RAM allocation to 6 or 8 gigabytes. Refer to the memory configuration topic below.

Memory Configuration

The  Tomcat bundle comes pre-configured with default memory usage settings. While the defaults are sufficient for initial usage, as your forms, business logic and submissions grow, so will the memory needs of the   server.

The first important step is to ensure that  is installed on a machine with sufficient cpu and ram. "Sufficient" depends on your  usage (number of users, number of forms in use, number of submissions per day, etc..).

You will know when you need to increase allocated memory when you see two common errors appear in the Tomcat logfiles <frevvo-home>//tomcat/logs. You can tune the frevvo/tomcat installation by editing <frevvo-home>/tomcat/bin/setenv.bat on windows and setenv.sh on unix.

You'll see something like this in setenv.[bat,sh]:

set JAVA_OPTS=-Xms128m -Xmx512m -Djava.awt.headless=true
-Dfrevvo.users.path="%CATALINA_HOME%\..\data\users"

OutOfMemoryError: Java heap space

SEVERE: Servlet.service() for servlet jsp threw exception
java.lang.OutOfMemoryError: Java heap space

To solve this edit setenv.[bat,sh] to increase the minimum and maximum heap size via the parameters: -Xmx and -Xms.

For example: -Xmx512m to -Xmx1g. Make sure also that the machine where  is installed has enough memory installed. If you change -Xmx to 1g your machine will need more then 1g ram.

OutOfMemoryError: PermGen space

MemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space

Java has a fixed space allocated for classes and other statics that is usually enough in normal cases, but could be quickly filled up if there is on the fly code generation or significant business logic in your forms.

To solve this edit setenv.[bat,sh] increase the maximum perm size via the paramenter: -XX:MaxPermSize

For example: -XX:MaxPermSize=128M

Live Forms as a windows service

You will have to edit frevvo/tomcat/bin/service.bat line 123 to increase the Java Heap and Permgen spaces. Here is an example of the line you need to edit in that file:

"%EXECUTABLE%" //US//%SERVICE_NAME% ++JvmOptions "-XX:MaxPermSize=128m 
-Djava.io.tmpdir=%CATALINA_BASE%\temp;
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager;
-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties" 
--JvmMs 128 --JvmMx 512

See the documentation on Tomcat Windows Service for more details.

TIFF Image Generator

Several  connector wizards, such as the Email and the PaperVision/ImageSilo wizards, allow you to select the form image attached to submission emails and stored into PaperVision/ImageSilo to be in TIFF image format. If the TIFF option doesn't appear in the wizard's Send Snapshot dropdown, then you have not yet installed the necessary TIFF image generator software.

...

You will now see the TIFF option in Send Snapshot dropdown. Form additional installation details and for various hardware platforms, please refer to the Java Image I/O Installation Guide.

Signature Date/Time

Digital Signatures require no configuration. However you can control the format of the date stamp that appears when forms are signed. These two parameters in <frevvo-home>\tomcat\webapps\frevvo\WEB-INF\web.xml are for signature configuration. The first you should never need to change.

<context-param>
  <param-name>frevvo.signature.class</param-name>
  <param-value>com.frevvo.signature.DefaultSignature</param-value>
  <description>Digital signature class name</description>
</context-param>
<context-param>
  <param-name>frevvo.signature.date.format</param-name>
  <param-value>d MMM yyyy, z</param-value>
  <description>Default date format for display</description>
</context-param>

Timezones

 concanocolizes all form submission data to UTC. In other words no matter which timezone you are in when you submit a form with a date, date/time, or time control, the form server will convert and store those values in UTC. If your form submission data is not correctly converted and stored in UTC then you likely have to update the timezones in your installed JRE/JDK. Oracle provides a timezone update tool. Run the TZUpdater tool with the following command: java -jar tzupdate.jar -u

See Oracle's Timezone Updater Tool for full details. 

Using Live Forms with reverse-proxies/SSL-accelerators

If your goal is to use   behind a reverse-proxy/load-balancer/SSL-accelerator you need to add a few configuration settings to /Tomcat to make sure  generate correct external urls.

When using a reverse-proxy, the external host, IP and/or port visible to browsers may be different than the host, IP and/or port seen by Tomcat. This causes a problem since  will generate urls in pages and forms that are either completely invalid, which is an easy case to spot since forms will not render at all, or valid by bypassing the reverse-proxy altogether, which are harder to identify except for side effects such as forms not resizing properly, or blocked by browser security restrictions.

For cases where you have only a web-server fronting  as a reverse-proxy (e.g. Apache or IIS), you can setup the web-server to communicate with Tomcat using AJP. This works since AJP provides additional metadata when communicating with Tomcat to indicate the actual remote host/ip/port instead of the web-server's host/ip/port.

However, using the AJP connector will not work for all cases. For instance, if you have a reverse-proxy/load-balancer/SSL-accelerator in front of your web-server, which is fronting /Tomcat, AJP would then report to Tomcat the host/ip/port of the reverse-proxy and not of the actual client. In these cases you have to leverage a feature provided by most reverse-proxies where they generate additional HTTP headers, like X-Forwarded-For, which contains the original client IP.  can then make use of these headers to override the host, IP and/or port of the external urls it generates. This is done using the following web.xml context parameters:

• frevvo.xforwarded.protocol.header - Identifies the name of the HTTP header containing the original request's protocol (SSL accelerators, for instance, will expose https to external clients by forward to internal services using http)
• frevvo.xforwarded.host.header - Identifies the name of the HTTP header containing the original request's host
• frevvo.xforwarded.port.header - Identifies the name of the HTTP header containing the original request's port

By default, 's web.xml will contain the following values for these context parameters:

<context-param>
 <param-name>frevvo.xforwarded.protocol.header</param-name>
 <param-value>X-Forwarded-Protocol</param-value>
</context-param>
<context-param>
 <param-name>frevvo.xforwarded.host.header</param-name>
 <param-value>X-Forwarded-Host</param-value>
</context-param>
<context-param>
 <param-name>frevvo.xforwarded.port.header</param-name>
 <param-value>X-Forwarded-Port</param-value>
</context-param>

You can change these parameter values to match the header names set by your reverse-proxy or change the reverse-proxy configuration to match these defaults. You can also leave any of these parameter values blank and  will then use the current request's protocol, host or port, if that makes sense in your case.

As a final note, if you plan to override these context parameter values and if you are using the  Tomcat bundle, we suggest doing so in frevvo/tomcat/conf/Catalina/localhost/frevvo.xml, since that would keep all your configurations in one place and makes it easy to upgrade  to newer releases. You can do that by adding the following to your frevvo.xml file:

<Parameter name="frevvo.xforwarded.protocol.header" value="X-Forwarded-Protocol" override="false"/>
<Parameter name="frevvo.xforwarded.host.header" value="X-Forwarded-Host" override="false"/>
<Parameter name="frevvo.xforwarded.port.header" value="X-Forwarded-Port" override="false"/>

Moving users to a different tenant

This section describes how to move a user to a different tenant. In the steps below, we will move the user john from a source tenant (will use tenant d) to a target tenant (will use mytenant as the target name).

1. If the target tenant does not exist, create it by following these steps. For the sake of this document, I will assume the target tenant id to be mytenant. 
2. Login to the target tenant as an admin and create a user with the same id as the user in the original tenant. In this example, the user id is john in the tenant mytenant.
3. Transfer the applications to the new user account in the target tenant
   1. Login to the source tenant as a tenant admin. For instance admin@d. 
   2. Navigate to Manage > Manage Users.
   3. Login as the user you want to move. 
   4. Navigate to the user's applications page. 
   5. Download each application for that user and save to a folder in your file system. 
   6. Logout
   7. Login as the user in the new tenant: john@mytenannt.
   8. Upload the applications you've downloaded in the previous steps. 
4. Move the submissions in the submissions repository. You need to run these steps in the database where you persist the  submissions. Please back up your database before moving forward. 
1. Login to your database.
2. Edit the script shown below to:
1. Replace the word johnwith the id of the user you are migrating.
2. Replace the tenant id d with the id of the source tenant. The default tenant in  is called d so if you are moving the user as part of an upgrade from 3.4.x chances are that your source tenant is d. 
3. Replace the word mytenant with the name of your target tenant 
3. Run the script shown below in your  submissions database.

update formsubmission
set tenantid='mytenant'
where id in (
select fs.id from formsubmission fs, formsubmissiontype fst 
where 
fs.formsubmissiontype_formtype_id = fst.id
and fst.ownerid='john'
and fs.tenantid='d'
)update formsubmissiontype
set tenantid='mytenant'
where ownerid='john'
and tenantid='d'

Verification:

1. Login as the user in the new tenant.
2. Verify that the submissions are properly being loaded for all forms. In the submissions repository page make sure to adjust the initial and end dates to a window of time that you know have submissions for that specific form.
3. Update references to the forms. After going trough the steps above, the URL to the forms owned by the user will be different than what they were originally. You need to update all references to the forms in published links and pages where the form should be embedded.

Show/Hide Tenant Login

 is a multi-tenant application. See the administration section on Manage Tenants. However, it is possible that all you need is a single tenant. If this is your case it simplifies  server login if you hide the tenant input on the  login page.

This can be changed by editing <frevvo-home>\tomcat\webapps\frevvo\WEB-INF\web.xml. Uncomment the frevvo.default.login.tenent.id parameter and set the param-value to the name of your one tenant. Next set the param-value of frevvo.login.show.tenant to false.

Here is how the parameters appear after editing:

<context-param>
        <param-name>frevvo.default.login.tenant.id</param-name>
        <param-value>ssotest</param-value>
        <description>Default Tenant</description>
</context-param>
<context-param>
        <param-name>frevvo.login.show.tenant</param-name>
        <param-value>false</param-value>
        <description>Show Tenant Box on Login Page</description>
</context-param>

Restart your  server and the next time you login you will only need to enter your username and password.

<Parameter name="frevvo.default.login.tenant.id" value="mytenant" override="false"/>  

frevvo.log. 

1. Go to <frevvo-home>/tomcat/lib
2. Open the file logback.xml for editing
3. Find <root level="INFO"> and change the word INFO to DEBUG. Save the file.

Loglevels are : TRACE, DEBUG, INFO, WARN, ERROR, OFF. ALL.  They are case -sensitive so be sure to type them in upper case.  The logging level is cummulative as shown below. Refer to this website for a description of the loglevels and some guidelines for using them.

• OFF = turns all logging off
• ERROR = ERROR 
• WARN = WARN + ERROR,  
• INFO = INFO + WARN + ERROR,
• DEBUG = DEBUG + INFO + WARN + ERROR,  
• TRACE = DEBUG + INFO + WARN +  ERROR
• ALL= turns all logging on

Configuring the logging level for catalina.log, localhost.log, host-manager.log, manager.log and local_access.log is done in <frevvo-home>/tomcat/conf/logging.properties Click here for more information. 

If you are having issues running the server in an environment with proxy setups, load balancers etc. the forms.ui.filter logger can help. This logger will output additional information to the frevvo.log file to assist in determining what the frevvo servlet is seeing. To enable this logger uncomment the following line in logback.xml:

<logger name="com.forms.forms.ui.filter" level="DEBUG" />

Logfile Rotation

The  tomcat bundle install will automatically rotate log files daily. The logfile is the only one affected. Let's say the current date is 6 - 19 - 2013. The current days logging is saved to the frevvo.log file located in <frevvo-home>/tomcat/logs.  On the next day, 6 - 20 - 2013,  the log from the previous day is copied to a logfile stamped with the previous day's date. (frevvo_2013-06-19). This date stamped frevvo.log is located in the <frevvo-home>\tomcat\logs\old directory. Logging for 6 - 20 - 2013 is saved in the frevvo.log in <frevvo-home>/tomcat/logs.

Session Timeout

's default web browser session timeout is 480 minutes. If a user is logged into the  server to design forms, or to view their task list, or is using a  form and filling in values but has not yet submitted the form, the session will expire after 480 minutes of inactivity. When the session expires the designer will have to re-login to  to continue designing forms and form users will have to get a new instance of the form and re-enter the values.

If the maximum number of concurrent users are logged in simultaneously, and any of them are idle for more than 480 minutes, the next person who tries to log in will be able to do so successfully.

The session timeout can be changed by editing <frevvo-home>\frevvo\tomcat\webapps\frevvo\WEB-INF\web.xml. The session timeout setting unit is minutes. For example, to change from an 480 minutes (8 hr) session timeout to a 1 hour timeout change 480 to 60.

<session-config>
    <session-timeout>480</session-timeout>

Editing Submissions

Designer users can view/edit submissions by clicking the edit link on the submissions panel. Non designer users can view/edit submissions by clicking on the Shared Items tab if they have been granted permission to do so by the designer via the Access Control feature. The frevvo.submission.edit .link parameter must be set to the default value of true, for the edit link to be visible to any  user. To disable the edit link on the submission panel, change the default value of true to false for the frevvo.submissions.edit.link configuration parameter in <frevvo-home>/WEB-INF/web.xml file. The web.xml file must be unzipped from the frevvo.war before it can be edited. Follow the instructions above to unzip, modify and rezip the war file.  

<context-param>  
    <param-name>frevvo.submission.edit.link</param-name> 
    <param-value>false</param-value> 
    <description>Show a link to edit the submission.</description> 
</context-param>

You can add the frevvo.submission.edit.link configuration property to the <frevvo-home>\tomcat\conf\catalina\localhost\frevvo.xml file instead of the web.xml file as discussed above. Here is an example that will disable submission editing when added to the frevvo war settings section of frevvo.xml:  

<Parameter name="frevvo.submission.edit.link" value="false" override="false"/>

 When the frevvo.submission.edit.link parameter has a value of false, the edit link is not visible on on form submission panels.

TIFF Image Generator

Several  connector wizards, such as the Email and the PaperVision/ImageSilo wizards, allow you to select the form image attached to submission emails and stored into PaperVision/ImageSilo to be in TIFF image format. If the TIFF option doesn't appear in the wizard's Send Snapshot dropdown, then you have not yet installed the necessary TIFF image generator software.

1. Download the JavaTM Advanced Imaging Image I/O Tools installer for your machine platform here. Your machine must be running have the Java Runtime Environment installed. For example on a windows platform:
   1. Download and run jai_imageio-1_1-lib-windows-i586-jre.exe
      
      
2. Execute the installer on your machine. This automatically copies the libraries necessary to create TIFF images into your java installation directory.
3. Restart the  server.

You will now see the TIFF option in Send Snapshot dropdown. Form additional installation details and for various hardware platforms, please refer to the Java Image I/O Installation Guide.

Signature Date/Time

Digital Signatures require no configuration. However you can control the format of the date stamp that appears when forms are signed. These two parameters in <frevvo-home>\tomcat\webapps\frevvo\WEB-INF\web.xml are for signature configuration. The first you should never need to change.

<context-param>
  <param-name>frevvo.signature.class</param-name>
  <param-value>com.frevvo.signature.DefaultSignature</param-value>
  <description>Digital signature class name</description>
</context-param>
<context-param>
  <param-name>frevvo.signature.date.format</param-name>
  <param-value>d MMM yyyy, z</param-value>
  <description>Default date format for display</description>
</context-param>

Timezones

 concanocolizes all form submission data to UTC. In other words no matter which timezone you are in when you submit a form with a date, date/time, or time control, the form server will convert and store those values in UTC. If your form submission data is not correctly converted and stored in UTC then you likely have to update the timezones in your installed JRE/JDK. Oracle provides a timezone update tool. Run the TZUpdater tool with the following command: java -jar tzupdate.jar -u

See Oracle's Timezone Updater Tool for full details. 

Using Live Forms with reverse-proxies/SSL-accelerators

If your goal is to use   behind a reverse-proxy/load-balancer/SSL-accelerator you need to add a few configuration settings to /Tomcat to make sure  generate correct external urls.

When using a reverse-proxy, the external host, IP and/or port visible to browsers may be different than the host, IP and/or port seen by Tomcat. This causes a problem since  will generate urls in pages and forms that are either completely invalid, which is an easy case to spot since forms will not render at all, or valid by bypassing the reverse-proxy altogether, which are harder to identify except for side effects such as forms not resizing properly, or blocked by browser security restrictions.

For cases where you have only a web-server fronting  as a reverse-proxy (e.g. Apache or IIS), you can setup the web-server to communicate with Tomcat using AJP. This works since AJP provides additional metadata when communicating with Tomcat to indicate the actual remote host/ip/port instead of the web-server's host/ip/port.

However, using the AJP connector will not work for all cases. For instance, if you have a reverse-proxy/load-balancer/SSL-accelerator in front of your web-server, which is fronting /Tomcat, AJP would then report to Tomcat the host/ip/port of the reverse-proxy and not of the actual client. In these cases you have to leverage a feature provided by most reverse-proxies where they generate additional HTTP headers, like X-Forwarded-For, which contains the original client IP.  can then make use of these headers to override the host, IP and/or port of the external urls it generates. This is done using the following web.xml context parameters:

• frevvo.xforwarded.protocol.header - Identifies the name of the HTTP header containing the original request's protocol (SSL accelerators, for instance, will expose https to external clients by forward to internal services using http)
• frevvo.xforwarded.host.header - Identifies the name of the HTTP header containing the original request's host
• frevvo.xforwarded.port.header - Identifies the name of the HTTP header containing the original request's port

By default, 's web.xml will contain the following values for these context parameters:

<context-param>
 <param-name>frevvo.xforwarded.protocol.header</param-name>
 <param-value>X-Forwarded-Protocol</param-value>
</context-param>
<context-param>
 <param-name>frevvo.xforwarded.host.header</param-name>
 <param-value>X-Forwarded-Host</param-value>
</context-param>
<context-param>
 <param-name>frevvo.xforwarded.port.header</param-name>
 <param-value>X-Forwarded-Port</param-value>
</context-param>

You can change these parameter values to match the header names set by your reverse-proxy or change the reverse-proxy configuration to match these defaults. You can also leave any of these parameter values blank and  will then use the current request's protocol, host or port, if that makes sense in your case.

As a final note, if you plan to override these context parameter values and if you are using the  Tomcat bundle, we suggest doing so in frevvo/tomcat/conf/Catalina/localhost/frevvo.xml, since that would keep all your configurations in one place and makes it easy to upgrade  to newer releases. You can do that by adding the following to your frevvo.xml file:

<Parameter name="frevvo.xforwarded.protocol.header" value="X-Forwarded-Protocol" override="false"/>
<Parameter name="frevvo.xforwarded.host.header" value="X-Forwarded-Host" override="false"/>
<Parameter name="frevvo.xforwarded.port.header" value="X-Forwarded-Port" override="false"/>

Moving users to a different tenant

This section describes how to move a user to a different tenant. In the steps below, we will move the user john from a source tenant (will use tenant d) to a target tenant (will use mytenant as the target name).

1. If the target tenant does not exist, create it by following these steps. For the sake of this document, I will assume the target tenant id to be mytenant. 
2. Login to the target tenant as an admin and create a user with the same id as the user in the original tenant. In this example, the user id is john in the tenant mytenant.
3. Transfer the applications to the new user account in the target tenant
   1. Login to the source tenant as a tenant admin. For instance admin@d. 
   2. Navigate to Manage > Manage Users.
   3. Login as the user you want to move. 
   4. Navigate to the user's applications page. 
   5. Download each application for that user and save to a folder in your file system. 
   6. Logout
   7. Login as the user in the new tenant: john@mytenannt.
   8. Upload the applications you've downloaded in the previous steps. 
4. Move the submissions in the submissions repository. You need to run these steps in the database where you persist the  submissions. Please back up your database before moving forward. 
1. Login to your database.
2. Edit the script shown below to:
1. Replace the word johnwith the id of the user you are migrating.
2. Replace the tenant id d with the id of the source tenant. The default tenant in  is called d so if you are moving the user as part of an upgrade from 3.4.x chances are that your source tenant is d. 
3. Replace the word mytenant with the name of your target tenant 
3. Run the script shown below in your  submissions database.

update formsubmission
set tenantid='mytenant'
where id in (
select fs.id from formsubmission fs, formsubmissiontype fst 
where 
fs.formsubmissiontype_formtype_id = fst.id
and fst.ownerid='john'
and fs.tenantid='d'
)update formsubmissiontype
set tenantid='mytenant'
where ownerid='john'
and tenantid='d'

Verification:

1. Login as the user in the new tenant.
2. Verify that the submissions are properly being loaded for all forms. In the submissions repository page make sure to adjust the initial and end dates to a window of time that you know have submissions for that specific form.
3. Update references to the forms. After going trough the steps above, the URL to the forms owned by the user will be different than what they were originally. You need to update all references to the forms in published links and pages where the form should be embedded.

Modifying Content Types for the Upload Control

The content types supported by  are configured through web.xml using the context parameter: frevvo.upload.file.types. A mime type that is not working for a certain content type can be added to the web.xml file for on-premise customers. Follow the steps above to unzip/rezip the <frevvo-home>/tomcat/webapps/frevvo.war file after the edits to the web.xml file are complete.

The context parameter, frevvo.upload.file.types is located in the <!-- Upload Control File Types and Corresponding Mime Types --> section of the web.xml file.

<context-param> <param-name>frevvo.upload.file.types</param-name> <param-value>pdf,MS Word,MS Excel,MS PowerPoint,MS Access,gif,jpeg,png,tiff,rtf,tar,zip,gzip,xml,bmp</param-value> <description>Upload Control File Types for restricting upload by type</description> </context-param>

In addition, there are context parameters for each supported mime type that corresponds to each context type. For example, the context param that has the mime types corresponding to MS Word is: frevvo.upload.file.type.ms_word.mimes. Note the naming convention for the context type part of the parameter - lower case and spaces replaced with _ 

<context-param>   <param-name>frevvo.upload.file.type.ms_word.mimes</param-name>   <param-value>application/msword</param-value>   <description>Allowed mimes for this type (comma separated).  Type names is lower cased and spaces replaced with _.</description>  </context-param>

Edits to the <!-- Upload Control File Types and Corresponding Mime Types --> section of the web.xml file should be reported to  customer support to ensure future releases include the added mime type in the web.xml file of future releases.

As a preferable alternative, the additional mime type can be typed into the Other Mime/Ex field on the Upload control property pane. Refer to Upload  control for more information.   

Rule Validation Timeout 

Rule validation is executed in a thread pool with a timeout. You can change the rule validation timeout value with the context param in web.xml - "frevvo.rule.validation.timeout". The default value is 2000 milliseconds. If validation javascript execution exceeds this timeout value, the Rule Validator will show : 

Form or Rule Level Validation Issue: Validation Failed Rule validation timed out, possibly due to unparseable rule JavaScript.

Max Size Attachment

You can set an upper bound limit server wide for the maximum size of an attachment that can be uploaded via the Upload Control by adding the frevvo.attachment.maxsize context parameter in the  web.xml file. See Modifying the web.xml file above for the details. The same result can be accomplished by overriding the property in the container level by modifying the frevvo.xml.file. This is the recommended approach as frevvo.xml is directly editable while the web.xml file is included in the frevvo.war zipfile that has to be extracted, modified and rezipped after the changes are made. To do that:

1. Stop .
2. Locate the frevvo.xml file under the frevvo installation. If you are using the tomcat bundle, it will be in <frevvo-home>\tomcat\conf\catalina\localhost.
3. Add the line:

<Parameter name="frevvo.attachment.maxsize" value="10485760" override="false"/>

      3. Replace the value,102400 in this example, with the maximum size of the attachment that you want. The value must be entered in bytes. The default value is 10485760 bytes.
