The RPG portions that I write for my open source projects
usually entail doing a lot of Java wrappering of an existing
API (i.e. JavaMail, JFreeChart). I wrapper them in a way
that makes them more easily called from the RPG environment
through keyed data queues. This route also has a huge
performance/resource benefit because there is only a single JVM
running on the system for all users.
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?
