I understand the benefits of having the runtime engine waiting on a data 
queue vs instantiating a JVM for each request.

The BIRT API is HUGE.  And much of it deals with interpreting the XML 
file.  So what sort of interface do you expose to the RPG developer?

I went to your Web site and looked at your RPG wrapper for JFreeChart, 
which looks great.  But the BIRT runtime engine is designed to get most 
of it's input from the XML file, and by running SQL queries for data. 
So I envision a very lightweight RPG interface.  Maybe just passing the 
name of the XML file, and maybe the name of the stream file to output 
the report to, and perhaps a few parameters.  Is that what you see?
