[b] Changes for session time out are not taking place.... Ur

[sumit.malik]

Hi Everyone,

I m running the sample's which are provided for Jboss EJB3Trail Demo application..

I have these configuration

Linux Fedora Core 4

Jboss 4.0.4 CA

Well, whenever i have deployed Session bean then try to get stub locally i get this exception after

00:32:05,174 ERROR [[/test]] Session attribute event listener threw exception
java.lang.RuntimeException: Could not resolve beanClass method from proxy call: public abstract void javax.ejb.EJBLocalObject.remove() throws javax.ejb.RemoveException,javax.ejb.EJBException

Here my session bean is working fine and i think ejb session time out is not working in smooth way. I have googled this problem and find few solution but none of them helped me out yet like i have changed and increased session bean passivate time but no result

<max-bean-life>300<max-bean-life> to <max-bean-life>300<max-bean-life>

and even i have changed

<domain name="Stateful Bean" extends="Base Stateful Bean" inheritBindings="true">
...
 <annotation expr="!class(@org.jboss.annotation.ejb.cache.simple.CacheConfig) AND !class(@org.jboss.annotation.ejb.Clus
tered)">
 @org.jboss.annotation.ejb.cache.simple.CacheConfig (maxSize=100000, idleTimeoutSeconds=3600
)
 </annotation>
...
 </domain>
[/code ]
but not yet i have gain any result and problem is still there....
So here i m just getting blocked



Looking forward for the help !!!

My Business Interface:

finally

If somebody can help me out..would be a great help...

Thanks
