configuration properties are configured in the frevvo-config.properties file in the <frevvo-home>\tomcat\conf directory. The frevvo-config.properties is a standard java properties file. Any valid context parameter can be configured as a property in this file. This file contains properties that define global customizations that apply to the <frevvo home>\tomcat\webapps\frevvo directory and the frevvo connector warfiles (Database Connector, Filesystem, SharePoint). For example, you can provide the client secret information for the Google Connector with a property in this file. 

The properties that can be added to the frevvo-config.properties file are discussed below. The configuration properties in the frevvo-config.properties file will override the properties configured in <frevvo-home>\tomcat\conf\server.xml file. Parameters, previously configured in the web.xml file included in the frevvo.war must be added to the frevvo-config.properties file as well.

Info

frevvo only supports/certifies  running in the tomcat container. Refer to our Supported Platforms for the list of Application Servers supported/certified by frevvo.

Converting Context Parameters to Properties  

The configuration properties follow a simple property name=value syntax. Let's say you had context parameters to default the tenant login and customize the placeholder on the login screen in the frevvo.xml file of your previous installation.

 The context parameters in frevvo.xml would look like this:

Code Block
titlefrevvo.xml from your previous Live Forms installation
<Parameter name="frevvo.default.login.tenant.id" value="your_tenant_id" override="false"/>
<Parameter name="frevvo.login.username.placeholder" value="user@<your_tenant_name>" override="false"/>

The configuration properties follow a simple property name=value syntax. Follow these steps to convert configuration parameters from previous releases to properties in the frevvo-config.properties file.

  1. Navigate to <frevvo-home>/tomcat/conf directory.

  2. Edit the frevvo-config.properties file.

  3. The Parameter name becomes the property name.
  4. Add an equal sign
  5. Add the value after the equal sign
  6. Repeat this for all custom parameters
  7. Save the file
Code Block
titlefrevvo-config.properties file in the v7.4.x installation
#Custom Tenant Id and Placeholder
frevvo.default.login.tenant.id=<your_tenant_id>
frevvo.login.username.placeholder=<@<your tenant name>

Here is an example of a frevvo-config.properties file that provides the client id and secret for the Box connector, the URL for the Filesystem connector, a property to turn on/off the Insight Server and a property to turn on DEBUG level logging for the frevvo.log and any frevvo connector logfiles.

Code Block
frevvo.box.connector.client.id=bttkldgy9r5td0kdu57v0h6h2gotjf03
frevvo.box.connector.client.secret=EM08T1IjiMFuyCP5OJWm5QPyTz0qcL4A 
frevvo.filesystem.connector.url=http(s)://<your server>:port/filesystem 
insight.enabled=true insight.service.url=http(s)://<your server>:port/insight 
frevvo.sharepoint.connector.url=http(s)://<your server>:port/sharepoint 
logging.level.root=DEBUG

Updating the frevvo-config.properties requires server re-start. You do not have to restart the Insight server.

frevvo tomcat bundle

In the frevvo tomcat bundle, the frevvo-config.properties file is located in the <frevvo-home>\tomcat\conf directory. The path to the frevvo-config.properties file is specified in the <frevvo-home>\tomcat\bin\sentenv.bat.sh files

Code Block
set CATALINA_OPTS=%CATALINA_OPTS% -Dspring.config.location="file:///%CATALINA_HOME%/conf/,file:///%CATALINA_HOME%/conf/frevvo-config.properties"

 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 the  server login if you default the @<tenantname> so the user only needs to enter their username to login. Customers who default the tenant login normally would also customize the placeholder on the login screen. Please read that topic for details.

  1. Stop Live Forms if it is running.
  2. Navigate to the <frevvo-home>\tomcat\conf directory
  3. Open the frevvo-config.properties file with a text editor.

  4. Add the frevvo.default.login.tenant.id property to the <frevvo-home>\tomcat\conf\frevvo-config.properties file and set the param-value to the name of your one tenant.

    Code Block
    titlefrevvo-config.properties
    frevvo.default.login.tenant.id=<your_tenant_id>


  5. Save the file
  6. Restart .

Note
  • There will be three additional logfiles when running Tomcat as a Windows service:
    • frevvoforms - stderr.YYYYMMDD and frevvoforms - stdout.YYYYMMDD for standard error messages and standard output stream, respectively. This is the default Tomcat behavior.
    • commons-daemon.YYYY-MM-DD.log for Windows Service errors
  • The Insight server no longer creates a log since the insight.war is integrated into frevvo.war. The messages formerly in the insight logs are now found in the in the <frevvo-home>/tomcat/frevvo_YYYY-MM-DD.log

When a person is using a form/flow then pauses for longer than the configured <session-timeout>, they will see the login screen.

  1. Stop
  2. Download the jai-imageio-core-1.3.1.jar here.
  3. Add it to frevvo classpath i.e. tomcat/lib folder
  4. Deploy pve.war (PVE Connector) in tomcat/webapps folder. Download the latest version of the PVE Connector from our frevvo Software Downloads Directory.
  5. Restart the  server. You will now see the TIFF option in the connector wizards Send Snapshot dropdown. The image shows the TIFF format option for the PaperVision or ImageSilo Connector wizard.

no longer supports the web.xml parameters for frevvo.xforwarded.protocol.header, frevvo.xforwarded.host.header, and frevvo.xforwarded.port.headers. The general recommendation is to rely on the Servlet Container for handling dynamic proxies. A better approach is to use tomcat's RemoteIp Valve instead.  Please see this documentation on the Apache Tomcat website for information about the RemoteIp valve functionality. This tomcat valve has been incorporated into our tomcat bundle.

Code Block

The show/hide pagebreaks icon  Image Removed Image Added on the Form Designer toolbar is a toggle to make PageBreak controls in your form on visible/invisible. When you create or edit a form, PageBreak controls will be visible. When you drag a PageBreak control from the palette onto the canvas it will be visible in the designer. If you save the formr/flow then edit it the PageBreak controls remain visible.  If you want to change the default behavior, i.e. make them invisible by default, add the frevvo.designer.showPageBreaks property to the frevvo-config.properties file. This property defaults to true. Setting it to false will hide the PageBreak control by default in the designer. Clicking the icon will make them visible.

...

The prompt and save of the form prior to additional pdf mapping can be controlled by the frevvo.form.save.on.mapping property. The property defaults to true. If set to false, the designer will not be prompted to save the existing pdf form before continuing pdf mapping and the editing instance will not be saved. This parameter applies only to forms, not flows.

The default value of the max_allowed_packet parameter in your MySQL server may not be large enough. Refer to this website for detailed information about the MySql configuration parameter. Increasing the max_allowed_packet variable setting in your MySQL Server from the default (1M) to something like 16M (16777125) fixes the issue. To fix the issue temporarily, run the following commands:

  • mysql -u root

  • set global max_allowed_packet=16777216

To permanently set it, choose one of the two methods listed below:

  • You can add the parameter  - max_allowed_packet=16M to the mysqld command line or (mysqld_safe command line) as shown: 

 mysqld --max_allowed_packet=16M 

  • Edit the MySql configuration file (my.ini on Windows/ my.cnf on Mac OS) and add max_allowed_packet=16777216 to the [mysqld] section. 

Code Block
[mysqld]
max_allowed_packet = 16M
  • Restart MySQL.
  • Restart frevvo. 
  • The setting will permanently take effect.

On Mac OS, you can access the my.cnf file by typing

  • sudo vi /etc/my.cnf

 The location of the my.ini/my.cnf file varies by configuration.

Skew error when logging into an Azure SAML tenant

Users logging into a Azure SAML tenant may encounter the error "Access Denied.  Authorization Required". Examination of the frevvo.log shows the following entry:

Code Block
Response issue time is either too old or with date in the future, skew 60, time 2016-06-01T05:49:25.330Z

This error is typically caused by a clock synchronization issue between the Service Provider (frevvo) and the Identity Provider (Azure) or a genuine delay in the connection. If you get this error, adding the com.frevvo.security.saml.response.skew property can be used to specify the time in seconds allowed between the request and the response from Azure to a value greater than the default value of 60 seocnds.

Follow these steps:

  1. Stop Live Forms if it is running.
  2. Navigate to <frevvo-home>\tomcat\conf
  3. Open the frevvo-config.properties file with a text editor.

  4. Add the parameter shown below with a value greater than the default value of 60 seconds. The example shown increases the timer to 120 seconds.

    Code Block
    com.frevvo.security.saml.response.skew=120


  5. Save the file.

  6. Restart .
  7. Retry the login.

In-house customers can change the maximum size for images uploaded to forms/flows using the Image control in the designers by adding the frevvo.asset.maxsize property to the frevvo-config.properties file. The default value is set to 2097152 bytes. Any uploaded file that exceeds the value in this parameter displays an error message to the designer so they can take corrective action.

Changing the Default Task Notification Email Message

If you want to change the default subject and body of the task notification email for your  server, add these properties to the frevvo-config.properties file.

Code Block
frevvo.task.notification.email.subject=New task
frevvo.task.notification.email.message=You can access your task list by clicking <a href="{task.perform.url}">this link</a>

Change the value in this parameter to anything you want. The task.perform.url template {task.perform.url} is a built-in template in  and it will always point to the specific task. Refer to the Task Notification Email Link topic for some other options. If you wrap the templates in an HTML <a> tag, it will generate a clickable link in the email.

If you do not want the link in your task notification emails to go there, you can remove it. The default message can include form control templates.
