17.1.1 Programming language for user functions

You can use Java to create user functions.

User functions must be implemented with the EADS-provided Function interface and archived as jar files.

Important note

If you attempt to use a user function that has been implemented with a Function interface whose version is more recent than the EADS server's version, valid operation is not guaranteed. In such a case, you need to edit and recompile the source programs.

A user function created with a Function interface whose version is 03-00 or later can be used with more recent versions of EADS servers.

You can place multiple jar files on a single EADS server. Therefore, if you want to execute multiple user functions on the same EADS server, you can use different jar files according to purpose.
