J2EE, RAS, JRC, and everything to do with Crystal Report XI

Question

Hello,
We are actually trying to make the JAR files provided with Crystal Reports XI Developper Edition.
The goal is to be able to generate a .rpt file based on some RAW data that we will collect from our iSeries Server, therefore giving the .rpt equivalent of the text-only report created with our application on i5/OS.
For the moment we don't care about interfacing the data from the text-only proto-report on the iSeries, we just care about modelling the instance of an .rpt file in Java.
The trouble is that we manage to create the object with ReportClientDocument newDoc = new ReportClientDocument(), but then the newDoc instance of this object is not accessible (the method .isOpen() returns false).
We also tried to open an existing .rpt file with the same methods to no success.
If anyone has any idea, or lead that could allow us to work our way through this wretched APIs, I would be very grateful.

I'm not referring to Servlet threading issues.
I'll clarify.
You have two threads, both entering ReportClientDocument.open(...) method.
Thread 4 is waiting to acquire 'com.crystaldecisions.reports.queryengine.av@15214b9'
Thread 0 is waiting to acquire ''com.crystaldecisions.reports.queryengine.av@12e0415'
So I'm thinking ??? are they the same objects?
My specific question concerning the ReportClientDocument is that both are calling open - i.e., trying to open a new report.  You wouldn't be trying to open different reports using the same ReportClientDocument - so was wondering if you've cached the RCD and trying to open two different reports at the same time on the same instance via different threads.
You'd normally tie a ReportClientDocument instance to a HTTP Session, to ensure each user gets their own copy.
Sincerely,
