Subject: Re: variable number of parameters in forms known at runtime From: Jose Quinteiro <[EMAIL PROTECTED]> === If I understand you correctly, you need to generate Java interfaces at run time. I believe this is possible. This article makes it sound like it's possible: http://java.sun.com/products/jfc/tsc/articles/generic-listener/index.html (Look at the end, where he talks about John Rose.)
You could then use the Dynamic Proxy API to implement these interfaces. This article introduces the API: http://java.sun.com/products/jfc/tsc/articles/generic-listener2/ I've used the Dynamic Proxy API - it's cool, but can be confusing. I've never tried to generate Java classes or interfaces at run-time, but it sounds like a cool project.
