That's my question, In the case I have different PC among locally caller and called SFSB. But the propagation requires the same PC, right? In other words, If a stateful session bean with an extended persistence context calls a stateful session bean with a different extended persistence context in the same transaction, an IllegalStateException would be thrown.
Am I missing something here, as then I will not be able to use a different PC of an EMF configured for different data source.
Take a look at

I had a look at your explanation in the blog, I must say it is very informative, my question is related somewhat to rule#5. I guess, your example uses the same datasource in the transaction of ReportServlet where it calls the UCM Bean.
