The superuser admin can configure server-wide global data. One common use is for forms deployed from a development/test form server to a production form server. You often need information such as Urls URLs configured one way in your dev/test environment and another way in your production envirionmentenvironment. For example, a database in the dev/test environment might be located at http://mytest:1024/database/listManagers and in your production environment at http://myprod:1044/database/listManagers.

 makes deployment from dev/test to production easier by enabling you to configure global data variables. For example, rather than hard-coding the Url URL to your database server you can write the Url URL using a template such as {dbUrl}/database/listManagers. Then define variable dbUrl one way in dev/test and another way in production.

To see all the places where templates can be used, refer to the chapter Templatized Strings.

Parameters defined in the _data.properties file can be retrieved using _data.getParameter in rules. Dynamic Labels, Help or Hints is an example showing how you can set the value of control labels, help and hints dynamically in a rule.

in Configuration Files

Properties listed in the  _data.properties can be overridden with properties prefixed by frevvo._data.<property name> in the following configuration files:. Note the syntax for the properties has a dot before and after the _data.

  • If you are using the frevvo tomcat bundle, you can add the frevvo._data properties in the:
    • <frevvo-home>/tomcat/conf/catalina/localhost/frevvo.xml - this is the easier and recommended location as this file is located outside the frevvo.war.
    • the web.xml file in the frevvo.war - this file is located in the frevvo.war file - the frevvo.war must be unzipped, the changes made and then rezipped. The modified frevvo.war must then be dropped into the <frevvo-home>\tomcat\webapps directory.
    • frevvo-config.properties - this file is typically created by the System Administrator to override parameters in a container web.xml file. This is most often used when the container is not file can be used for any container including tomcat.

This approach is helpful when deploying multiple environments. Let's say your organization has a Development, Production and UAT environment for .  All three have the frevvo DB Connector configured for that environment. If you make a copy of Production environment and database to create your UAT environment, you would have to download the _data properties file, make the changes to point to the DB Connector in the UAT environment, then upload the file again.

It is easier to create property files with the a frevvo._data.servername property dbURL parameter pointing to the correct locations outside of the databases. for each environment.

This parameter in the frevvo.xml file would look like this:

Code Block
<Parameter name="frevvo._data.dbURL" value="http://<server>:<port>/database/listManagers" override="false" />

The same parameter in the web.xml file would look like this:

Code Block
<context-param>  
    <param-name>frevvo._data.dbURL</param-name> 
    <param-value>http://<server>:<port>/database/listManagers</param-value> 
</context-param>

The same parameter in the frevvo-config.properties file would look like this:

Code Block
frevvo._data.dbURL=http://<server>:<port>

As mentioned above, you can write the URL using a template such as {dbURLl}/database/listManagers. Then define the variable dbURL for the development, UAT and Production environments in the properties file you are using..
