Creating custom function types

Top Previous Next

The extensibility of JSCAPE MFT Server Triggers is not limited to the creation of custom action types, MFT Server's extensible API also enables you to create your own custom functions.

For a custom function class to work, it must:

•	Extend the abstract class com.jscape.inet.mft.Function;

•	Implement the abstract methods: getName(), getTemplates(), and evaluate(Object[] value)

Other requirements

Before you compile your custom function, make sure you include all Java libraries found in the libs directory relative to your JSCAPE MFT Server installation in your IDE project CLASSPATH.

To make your custom functions accessible from JSCAPE MFT Server, you must create a JAR archive that contains your custom functions, place it in the libs/ext directory relative to your JSCAPE MFT Server installation, and restart your JSCAPE MFT Server instance.

In addition, any third party libraries that your functions depend on should be placed in libs directory of your JSCAPE MFT Server installation.

You must also include a MANIFEST.MF file in your JAR archive that identifies those classes that are functions.

Lastly, to verify that your function has been successfully installed, login to the JSCAPE MFT Server administrative interface, navigate to the Triggers module of your domain, and click the Functions tab. Your custom function should be found there.
