How do I set up "nopassivation" caches? I'll give it a go.
BTW out of sheer exasperation I spent the day deploying my application under
Weblogic 5.1, and it works just fine, no deadlocks.
Now I know that doesn't necessarily mean jBoss has a bug, but it sure looks
like it at this stage. I am relatively new to J2EE but I have checked my
design and code pretty thoroughly. I am also following best practices, no
reentrant beans, access entities via session, proper transaction control etc
I still want / need to get my app working under jBoss so would appreciate
any input.
