# Configuring the function in Rational® Integration Tester

After the function is developed and a plug-in is generated, you should communicate that to Rational® Integration Tester by configuring the function.

## About this task

For details on developing the function and generating the plug-in, see Create the plug-ins in Eclipse and Implementing the function class.

To configure the function for use in Rational® Integration Tester, do the following steps:

## Procedure

- If you did not yet generate the plug-in in the Functions folder of the Rational® Integration Tester project, then copy it there now (for example, if your project is stored under C:\OneTestAPI\Project1, copy the plug-in JAR or plug-ins folder to C:\OneTestAPI\Project1\Functions).
- In Rational® Integration Tester, click to load all functions in the Functions folder and the plug-ins subfolder.
- Optionally, click
to verify that your custom function is loaded.
The Functions dialog displays a list of all the plug-ins that are known to Rational® Integration Tester, sorted alphabetically by function name.

Note: If the new function is not listed, review the steps that were carried out to ensure that nothing was missed.You can now use the custom function like any other function in Rational® Integration Tester.
