Administration of reCAPTCHA Keys
provides frevvo provides a default reCAPTCHA key. No other configuration steps are required for on-premise customers that choose to use the default key. This default reCAPTCHA key is:
- NOT configured to a particular host/domain server
- NOT configured for Google to perform any host/domain name checking on the challenge step. However, will frevvo will perform a host/domain verification on the verification step so that any attempts at site key spoofing are blocked.
- Considered secure.
...
The frevvo.recaptcha.hostcheck property controls the domain/host verification on the verification step that is done by frevvo. The values for this property can be set to true or false. If you use a custom key with Domain Name Validation configured, add this property to the frevvo-config.properties file with a value of false. Otherwise, add it to frevvo-config.properties with a value of true.

External URLs
The External URL should always be set up when frevvo tomcat is running behind a proxy. Setting the correct external URL is necessary when frevvo either redirects to an external system that is sensitive to the originating address e.g. SAML Identity Provider, OAuth server, etc. or generates a URL for external use e.g. a share URL.
Tomcat is already configured to accept the standard x-forwarded headers. If the proxy is providing these in the request then nothing needs to be done. If the headers are custom, then frevvo can be configured to do the translation. If these headers are not being provided, then you need to configure the tomcat connector proxy attributes.
Proxy with X-Forwarded headers configured
This is the most flexible setup. You do not need to make any changes in frevvo to use this as tomcat is already configured to handle the standard x-forwarded headers which are as follows:
- X-Forwarded-Proto: the protocol of the incoming request (http or https).
- X-Forwarded-Host: the host name of the incoming request
- X-Forwarded-Port: the port of the incoming request
In the event you use non-standard header names, you will have to configure the the frevvo's <frevvohome>\tomcat\conf\frevvo-config.properties file to handle the translation.
Expand | |||||
---|---|---|---|---|---|
| |||||
For example, if you prefer to use a parameter called X-Fwd-Scheme instead of X-Forwarded-Proto, simply add the appropriate context parameter and make sure that your proxy is setting a header with the new name. The defaults are shown below. Replace the values on the right side of the '=' with your corresponding custom header name.
|
Configure a Tomcat Proxy
Proxy attributes are set up on the tomcat connector that the proxy is forwarding requests to, which could be the HTTPS or the HTTP connector of the <frevvo-home>\tomcat\conf\server.xml file. For example, if SSL is being terminated in the proxy then it forwards to the HTTP connector (as shown below). Add the properties proxyName, proxyPort, scheme and secure.
Code Block | ||
---|---|---|
| ||
<Connector port="8082" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="40000" maxHttpHeaderSize="32768" useBodyEncodingForURI="true" proxyName="<myexternalhost>" proxyPort="<myexternalport>" scheme="https" secure="true" /> <!-- makes sure that uri parameter are decoded as utf-8 --> |
will frevvo will always redirect to this server. Captcha requests will use the same protocol (HTTP or HTTPS) as the external URL.
Default Internal Port
uses frevvo uses a connector on port 8081 for internal requests. As indicated in the server.xml, changing the frevvo internal connector 8081 settings in the server.xml file can cause unexpected changes, and is not advised.
The connector with port 8081 is configured in the server.xml file. Please ensure this port is available for to for frevvo to use.
Code Block |
---|
<!-- A "Connector" used for internal frevvo calls: DO NOT MODIFY IT! --> <Connector address="127.0.0.1" port="8081" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="40000" maxHttpHeaderSize="32768" useBodyEncodingForURI="true" /> <!-- makes sure that uri parameter are decoded as utf-8 --> |
If you need to change the internal port, follow these instructions. The only case where frevvo.internal.port may need to be changed is if port 8081 is already in use by another application.
In the server.xml, replace port 8081 in all locations with the port number of your choice. Make sure the new port is open and available for for frevvo's use.
Code Block <Connector address="127.0.0.1" port="<port>" protocol="org.apache.coyote.http11.Http11NioProtocol" connectionTimeout="40000" maxHttpHeaderSize="32768" useBodyEncodingForURI="true" />
In the frevvo-config.properties file, add the frevvo.internal.port property and set it to the same port number used in step 1.
Code Block frevvo.internal.port=<port>
Default External Port
uses frevvo uses a connector on port 8082 for external requests. By default the tomcat frevvo tomcat bundle is configured to bind to port 8082. Please ensure this port is available for to for frevvo to use. You can change the port by:
- Editing the <frevvo-home>/tomcat/conf/server.xml file.
Search for this line in the file:
Code Block <Connector port="8082" protocol="org.apache.coyote.http11.Http11NioProtocol"
- Change the Connector port.
You can also change the default https connector port.

Browser Support
does frevvo does not support BETA versions of browsers and there is often a delay so that we can test newly released browser versions before they are supported. In previous releases, was frevvo was configured to use a list of supported browsers. An error message and a link to override the error would display if the system was accessed using an unsupported browser. If you want to warn users if they access using access frevvo using an uncertified browser, configure a list of allowed browsers using the the frevvo.supported.browsers parameter in the <frevvo-home>\tomcat\conf\frevvo-config.properties file
- Stop frevvo if it is running.
- Navigate to <frevvo-home>\tomcat\conf
- Open the frevvo-config.properties file with a text editor.
Add the properties with your modified values then save the file.
- Restart Restart frevvo
Add the user agent for the browsers you want to support '''in lower case only'''. For example, to allow all versions of Firefox, add the string 'firefox' (without the quotes) to the property value. It will match all versions of the Firefox browser. Internet Explorer 11 requires the use of the agent identifier, trident/7. Separate the values with a comma.
...
The tomcat manager is accessible in the bundle at http://<server-name>:8082/manager/html. The default Tomcat Manager user name/password are preset to frevvo/frevvo. If you wish to change the password, you may do so by editing the file <frevvo-home>\tomcat\conf\tomcat-users.xml.
Tomcat SSL
can frevvo can be configured to handle HTTPS connections from users. The tomcat frevvo tomcat bundle you downloaded from www.frevvo.com is pre-configured with a self-signed certificate for development and testing. This self-signed certificate enables to enables frevvo to handle HTTPS connections out of the box. However before deploying your forms to production you may want to replace this with your own certificate.
...
Code Block | ||

recommends frevvo recommends reviewing your Certificate Authority's documentation for detailed steps to configure your certificate in Apache Tomcat. Additional info on how to use SSL on tomcat can be found on the Apache/Tomcat website.
There are multiple ways of configuring certificates depending on their format. For example, a PKCS#12 (pfx or p12) certificate doesn't have to be imported into the keystore. It can be configured directly as:
Code Block |
---|
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" sslEnabledProtocols="TLSv1+TLSv1.1+TLSv1.2" keystoreFile=C:\CERTDIRECTORY\CERT.pfx" keystorePass="YourPassword" keystoreType="PKCS12" connectionTimeout="40000" maxHttpHeaderSize="32768" useBodyEncodingForURI="true"/> |
However, PKCS#7 or P7B formats require importing the certificate chain into the keystore. The Certificate Authority needs to provide all the intermediate certificates to be imported.
Currently you must not disable disable frevvo's http port. In a future release this will be allowed. Disabling Disabling frevvo's http port will cause your form server to malfunction as requires as frevvo 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 deploy frevvo behind an Apache or IIS server. Close the http port on Apache or IIS but leave tomcat's http port open so that can that frevvo can POST back to itself when needed over http but no one outside can access it.
...
Tomcat Logfiles
By default, the server the frevvo server writes useful logging information to a daily logging file located here: <frevvo-home>/tomcat/logs. You will see the logfiles listed below in <frevvo-home>/tomcat/logs. The current date appends to the logfile names.
- catalina.YYYY-MM-DD.log - this log captures the stderr and stdout of the tomcat process including startup/shutdown messages. This is usually a small file.
- frevvo_YYYY-MM-DD.log - all messages frevvo messages are logged to this file. A new log with the current date appended to it is created daily.
- localhost.YYYY.MM.DD.log - this tomcat logfile should be empty.
localhost_access_log.YYYY - MM - DD.txt - is used to log all HTTP accesses to Tomcat. It is enabled by the following entry in <frevvo-home>/tomcat/conf/server.xml. Comment out the statement below to turn off logging to this file if it is not needed.
Code Block <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %{begin:dd/MM/yy:H:m:s.S}t "%r" %s %b "%{Referer}r" "%{User-Agent}r" [%I %{JSESSIONID}c %{X-Correlation-Id}o %{Location}o]" />
- host-manager.MM-DD-YYYY.log - this logfile is part of the tomcat distribution and is empty by default. It is a log file for the host-manager web application that is used to manage virtual hosts in tomcat. The host manager web-app is typically not needed because is frevvo is preconfigured. Messages are written to this log only if the host-manager web application is being used.
- manager.MM-DD.YYYY.log - this logfile is part of the tomcat distribution and is empty by default - this is the log file for the tomcat manager web application which is used to check the status of web apps, memory usage etc. Messages are written to this log only if the manager web app is being used.

Session Timeout
frevvo's default web browser session timeout is 30 minutes. If a user is logged into the server frevvo server to design forms, or to view their task list, or is using a form frevvo form and filling in values but has not yet submitted the form, the session will expire after 30 minutes of inactivity. When the session expires the designer will have to re-login to to frevvo 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 30 minutes, the next person who tries to log in will be able to do so successfully.
The default server frevvo server session timeout can be overridden for each tenant. The tenant admin can edit the tenant and make the changes there.
When a person is using a form/flow then pauses for longer than the configured <session-timeout>, they will see the login frevvo login screen.
When a person is using a form/flow 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 or try to submit a form from a timed out session.

Timezones
concanocolizes frevvo standardizes 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 JDK. Oracle provides a timezone update tool. Run the TZUpdater tool with the following command: java -jar tzupdate.jar -u

Uploading a CSV file to add or edit users normally runs quickly. However, if uploading a file in which the notifyIfNewUser property is TRUE for a large number of rows, this process may slow down on some email servers. Tenant Admins can configure to configure frevvo to run CSV-file user uploads in batches to improve upload time if needed. To adjust batch load size, configure the following property in <frevvo-home>\tomcat\conf\frevvo-config.properties.

Using frevvo with reverse-proxies/SSL-accelerators
If your goal is to use behind frevvo behind a reverse-proxy/load-balancer/SSL-accelerator you need to modify configuration settings to frevvo/tomcat to make sure generate frevvo 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 frevvo 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.
no frevvo 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 frevvo tomcat bundle.

The frevvo API uses an http connection pool which implies that connections are reused for a given route. In some cases, an API call (such as a rule or doc action) may fail intermittently due to a connection reset or a socket read timeout. Setting the property http.connection.maxidletime in the frevvo-config.properties file may resolve this issue. This property sets the idle time in milliseconds beyond which the connection will be closed by the monitor. By default, it is not set and hence there is no monitor running. Once it is configured with a positive value e.g. 30000, the monitor runs every 1 second looking for expired idle connections and closes them.

If you are using MySQL, and you upload a large image or you are using a workflow that contains a large pdf, frevvo, you may see this error: 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: |

Skew error when logging into an Azure SAML tenant
Users logging into a Azure frevvo 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 frevvo request and the response from Azure to a value greater than the default value of 60 seocnds.
Follow these steps:
- Stop frevvo if it is running.
- Navigate to <frevvo-home>\tomcat\conf
- Open the frevvo-config.properties file with a text editor.
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
Save the file.
- Restart frevvo.
- Retry the login.
Configure the max size for Images in your form/flow
In-house customers can change the maximum size for images uploaded to forms/flows using the Image control in the designers frevvo 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.
...
- Stop frevvo if it is running.
- Navigate to <frevvo-home>\tomcat\conf
- Open the frevvo-config.properties file with a text editor.
Add the frevvo-asset-maxsize property. Change the value to the maximum allowable image size in bytes.
Code Block frevvo.asset.maxsize=2097152
Save the file.
- Restart frevvo.
Changing the Default Task Notification Email Message
If you want to change the default subject and body of the task notification email for your serveryour frevvo 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 in frevvo 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.
Non-default Database Schema
If you use a custom schema (anything other than 'dbo'), you must add the following property to the <frevvo home>/tomcat/conf/frevvo-config.properties file. This property's default value is 'dbo'.

Secure Passwords in Tomcat
Security audits may point out that some secrets are stored in clear text in tomcat configuration files. Here is a list of (known) secrets that are currently stored in clear text by default:
Tomcat JDBC and SMTP configurations in Tomcat’s <frevvo-home>\tomcat\conf\server.xml
Database password in <frevvo-home>\tomcat\conf\dbconnector.properties
Google Connector’s Client Secret in <frevvo-home>\tomcat\conf\frevvo-config.properties
frevvo’s SAML keystore password in <frevvo-home>\tomcat\bin\setenv.bat and the service.bat files for the Windows OS or setenv.sh for UNIX/Linux OS
Tomcat, and thereby thereby frevvo, does not support encryption out of the box. There are two main options for securing this information.
Limit access to Tomcat files
The first option is limiting access to the file so that it can only be read by the user that Tomcat process runs as and root (or the administrator on Windows). Here are two relevant articles about Tomcat passwords that provide suggestions for limiting access and masking sensitive information:
- https://cwiki.apache.org/confluence/display/TOMCAT/Password.
- https://wiki.owasp.org/index.php/Securing_tomcat#Cleartext_Passwords_in_CATALINA_HOME.2Fconf.2Fserver.xml
For the Database Connector, you can define the data source at the container (tomcat) level for some added security. Please see this documentation which explains how.
OS Environment Variables
Starting in Tomcat v9.0.34 ( v9frevvo v9.0.15+) Tomcat introduced support for environment variables in server.xml. (See Apache Tomcat 9 (9.0.54) - Changelog for details.) This new capability is disabled by default in Tomcat but can be enabled by adding the following property to conf/catalina.properties.
...
The same OS environment variable approach can also be used in the Database the frevvo Database Connector out of the box since it is a SpringBoot application. Consider the following dbconnector.properties snippet concerning the BIRT JDBC connection info:
...
SAML Keystore Password
SAML support in also in frevvo also requires a keystore, which is encrypted by default, and a keystore password used by frevvo to access the keystone. The SAML keystore password is currently set in clear text as a frevvo property, but can also be set using an OS environment variable (frevvo is a SpringBoot app like the DBC). So, instead of setting the com.frevvo.security.saml.password property in frevvo.properties, you can, instead, define an OS environment variable named COM_FREVVO_SECURITY_SAML_PASSWORD=mypassword. This will make sure the frevvo.properties file is free of this secret.

- Stop frevvo if it is running.
- Navigate to <frevvo-home>\tomcat\conf
- Open the frevvo-config.properties file with a text editor.
Add the frevvo-certificate.signature property with a value of true.
Code Block frevvo.certificate.signature=true
Save the file.
- Restart Restart frevvo.
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.
On Mac OS, you can access the my.cnf file by typing
The location of the my.ini/my.cnf file varies by configuration.
