RE: RE: Exception when reloading my EAR / linked with pool of session bean ?

Hello again 

 

Sorry but I am really stuck with this problem L

I solved some points by removing some @Remote and @Local annotations on my SL session bean.

But when I launch a remote EJB client, I got the same awful error :

 

Caused by: java.lang.IllegalArgumentException: Cannot get element in the pool

        at org.ow2.easybeans.container.session.stateless.StatelessSessionFactory.getBean(StatelessSessionFactory.java:107)

        at org.ow2.easybeans.container.session.stateless.StatelessSessionFactory.localCall(StatelessSessionFactory.java:124)

 

and

        at org.ow2.util.pool.impl.enhanced.EnhancedPool.get(EnhancedPool.java:197)

I cannot see anything on Internet with these errors L

Thanks

Serge

To be more precise, I noticed this when I stop Jonas, there is a kind of warning :

 

"WebappClassLoader.clearReferencesThreads : The web application [/OrangeOpenCloud] appears to have started a thread named [WorkThread-1/61] but has failed to stop it. This is very likely to create a memory leak."

 

Maybe it is the origin of the problem ?

Objet : [jonas] Exception when reloading my EAR / linked with pool of session bean ?

 

Hello there,

 

When I redeploy my EAR on Jonas (5.2 version) I noticed this exception (not every time) : 

 

AbsTransactionInterceptor.handleContextContainerTransaction : Exception (not application exception) in business method

javax.ejb.EJBException: java.lang.IllegalArgumentException: Cannot get element in the pool at org.ow2.easybeans.proxy.client.AbsInvocationHandler.handleThrowable(AbsInvocationHandler.java:176)

 

It seems to be linked with the loading of a Timer session Bean and the associated pool :

Please can you help me ? Is there a setting in Jonas to change to increase session bean pool ?

 

Thanks a lot.
