I am working on an interface between our existing application and another
vendors application. They have provided a 'JavaTM 2 Platform, Standard
Edition, v 1.4.2 API Specification' which I have been able to use to call
functions in their API.

Now I want to do the reverse, put together an API that will consist of Java
methods, etc. that they can call from there side, that will be implemented
using PowerBuilder 10.x and whatever other tools I need (ejb or whatever).
I just need to know that it can be done and where to start looking.

Thanks in Advance,

Scott Ewine
