Category: JBossTX Group: v3.2 >Status: Closed >Resolution: Invalid Priority: 5 Submitted By: Colin Sampaleanu (colins) Assigned to: Nobody/Anonymous (nobody) Summary: deadlock on nested transactions Initial Comment: I am able to reproduce a deadlock situation (when it shouldn't be happening) in both JBoss 3.2 beta 2 and 3.0.4, using a certain combination of EJB calls, and using either the regular (non-XA) or XA oracle datasource. The sequence of calls is: - client calls Stateless Session Bean (transaction required) - SLSB tried to create CMP 2.0 Entity bean. - ejbCreate method of entity bean needs an ID, so it calls a method on a sequence generator Stateless Session Bean (transaction required) - sequence session bean tries to load and call a method on a sequence entity bean, using CMP 1.1, (NEW transaction required) At this point, there is a hang/deadlock. JBoss gives up after about 4-5 minutes, saying there was a probable deadlock. I have a complete standalone ant project which builds and ear file, that demonstrates the problem. The EAR is small enough that I could attache it here, but the source is about 3-4MB with all the libs needed to compile (e.g. oracle jdbc drivers, etc.), so I would rather just email the stuff to the appropriate person. I have attached a copy of the server.log file, as well as a complete thread stack dump (supplied by somebody else running the deadlock test) during the deadlock. ---------------------------------------------------------------------- >Comment By: Colin Sampaleanu (colins) Date: 2002-12-12 03:26 Message: Logged In: YES user_id=71283 I have tracked down the problem to part of the J2EE spec relating to transactions, which is left as containter-specific. In this case, WebLogic and JBoss do not behave the same, and the problem code relied on the WebLogic behaviour. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=649143&group_id=22866 ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
