[EJB 3.0] - EJB3 Timers: OutOfMemory error when handling large number of

by abollaert

Hi, I have an MDB that needs to start a timer in some cases when it receives a message. This is implemented in terms of an EJB3 timeout method. However, it seems that JBoss is creating a thread per timer. This is causing OutOfMemory errors because the VM cannot allocate new threads for the timers, eventually resulting in a crash of the server when handling large loads (20000 timers). It is necessary to create the timers, so changing the code to not use timers is not an option. I've googled around a bit for a a solution to this problem, and came across https://jira.jboss.org/jira/browse/EJBTHREE-1330. This issue does mention a workaround (using StrictMaxPool instead of the standard evergrowing ThreadlocalPool. But my MDBs are already using the StrictMaxPool (15 instances strictMaximum), and this does not seem to help. I would assume that there is a way to configure the TimerService itself to use a thread pool, but the Jira issue does not specify how this could be done, nor does the documentation. I would really appreciate it someone could shed some light on this... If there is no way of limiting the threads created by the TimerService, I'll have to change the implementation. But if there is some way of changing this, I would like to know how to do this because it would be the most elegant solution...

[JBoss jBPM] - Re: required fields for transitions?

by jbarrez

Take a look at the taskController. You can define process variables as 'required' in this controller (in the process xml). The TaskController is an interface, so it is easy to change the functionality if needed (eg transition specific variables?)

[Security & JAAS/JBoss] - Re: Security context null when logging out from Jboss

by anil.saldhana＠jboss.com

The idea is that when you log out, you need to restore the identity of the user that was on the thread path before the ClientLM got involved. Something like: userA----now_I_invoke_ejb_with_userB --- ejb_op ----- userB_logout Now ClientLM with the option will be set the thread to have userA as the identity.

[JBoss AOP] - Standalone after-throwing sample works fine, but not work on

by ienvyou

Hello, Thank you for JBoss AOP effort first. I'm using JBoss AOP and trying to use after-throwing for exception handling. As like subject, the after-throwing sample in jboss-aop-2.0.1.GA works fine but same sample on AS5.0.1GA doesn't work. These are my environment : JDK : JDK1.6.0 Platform : Microsoft Windows XP JBoss AS : JBoss AS 5.0.1 GA I also included javaagent switch and loadtime config to true in conf/bootstrap/aop.xml -javaagent:deployers/jboss-aop-jboss5.deployer/pluggable-instrumentor.jar Exception : 14:14:50,188 INFO [STDOUT] Catching Exception org.jboss.aop.advice.NoMatchingAdviceException: No matching around advice called 'afterThrowing' could be found in Aspect for joinpoint Method[method=public void jboss.POJO.throwPOJOExceptionMethod(java.lang.String) throws POJOException] Is there any missing point here? Thanks in advance!
