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 configured one way in your dev/test environment and another way in your production environment. 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.

Live Forms makes deployment from dev/test to production easier by enabling you to configure global data variables. For example, rather than hard-coding the URL to your database server you can write the 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.

Setting Global Data in _data properties file

To define your server-wide global data:

  1. Click the Download icon. This will download an empty default file. 
  2. Add your global data to the file. See below for an example of the syntax. Save the file.
  3. Login to the form server as the superuser admin
  4. Click Manage Default _data
  5. Click Browse...
  6. Locate your newly created file.
  7. Click Upload.
  8. For subsequent edits of the file, simply download the file previously uploaded by clicking on the Download icon. Edit the file and upload the modified file as described above.

 Here is an example of the syntax for a file:

You will see the following message when the file has been successfully uploaded to Live Forms:

Parameters defined in the 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.

Setting Global Data in Configuration Files

Properties listed in the 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:
    • - this file is typically created by the System Administrator to override parameters in a container web.xml file.

This approach is helpful when deploying multiple environments. Let's say your organization has a Development, Production and UAT environment for Live Forms.  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 a frevvo._data.dbURL parameter pointing to the correct locations for each environment.

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

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

The same parameter in the file would look like this:

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..
