I changed all the commit options in the standardjboss.xml file to C, results
stayed the same for JBOSS

Subject: Re: [JBoss-user] Differences in ejb methods called for BMP
beans
I'd expect that output from JBoss if you are using commit option A (the
default) and those beans had been accessed recently - since option A
caches the bean's state aggressively, they need to ejbActivate to
transition from the 'pooled' state to the 'ready' state, and need to
ejbLoad prior to a business method call (option A means JBoss is the
only thing touching that database, and can therefore assume that what it
has from the last transaction is what's in the database)
The Orion sequence is correct also. If my assumption that those beans
had been accessed prior to the trace below is true (and if it isn't
you'll see that you're getting the wrong (no) data), both servers are
behaving according to the spec (with Orion using commit option C) and
'more correct' is not meaningful.
Try setting JBoss to commit option C and see how that changes the
calling sequence. Then try option B, just for fun 8^})
