[jboss-dev-forums] [Design of the JBoss EJB Container] - Application Error: tried to enter Stateful bean with differe

Hi, I have a problem. Often when i invoke some EJB StateFul methods in my web application, this throws the following exception(at the end of my post). The problem occurs on JBOSS 4.0.5.GA while it works correctly on Weblogic 7.0. Throughs several searches on the web i found the problem is due to concurrent calls to the EJB methods from more clients that not allowed in EJB Stateful, but i didn't find any solutions. Is there someone that could help me ? Thanks in advance. 2008-02-27 20:19:54,457 ERROR [org.jboss.ejb.plugins.LogInterceptor] EJBException in method: public abstract java.lang.String
