Deploy advanced Java functions on the XI J2EE server

Hello XI - Java Gurus,

I have written some useful Advanced user functions for my XI mappings. At the moment I have import my jar/zip file

as an imported archive for each namespace/SC.

Now my question: What are the steps to deploy my jar file to XI J2EE Engine so that all my mappings can use them.

The best would be to put an import statement in the advanced user function and then just call my objects/methods.

Is that possible? I would really appreciate step-by-step instructions.

Thanks so much

Stefan
