Hi, I am using Jboss-4.0.3sp1 and EJB. My Issue: In my application, i do a search. During this search, it goes for an EJB call. Now, if suppose a user cancels the search operation, immediatly after doing the search then i am getting the error below. Its throwing this error on the console and throwing it to the app screen also. Also, sometimes it doesnt throws this error but takes around 5 seconds to return the application to its normal form (By showing an hour glass) I can understand that its trying to destroy that EJB call and the EJB is already engaged in a transaction means the EJB is still not passivated. But i am not able to find the rootcause of this problem. I am getting an EJBException. Here is the error log: ********************************************** 15:53:39,585 ERROR [LogInterceptor] EJBException in method: public abstract void javax.ejb.EJBObject.remove() throws java.rmi.RemoteException,javax.ejb.RemoveException: javax.ejb.EJBException: Application Error: tried to enter Stateful bean with different tx context, contextTx: TransactionImpl:XidImpl[FormatId=257, GlobalId=dscp12800/119, BranchQual=, localId=119], methodTx: TransactionImpl:XidImpl[FormatId=257, GlobalId=dscp12800/120, BranchQual=, localId=120] at org.jboss.ejb.plugins.StatefulSessionInstanceInterceptor.invoke(StatefulSessionInstanceInterceptor.java:268) at org.jboss.ejb.plugins.CallValidationInterceptor.invoke(CallValidationInterceptor.java:48) at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:106) at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:335) at org.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:166) at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:192) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invoke(ProxyFactoryFinderInterceptor.java:122) at org.jboss.ejb.SessionContainer.internalInvoke(SessionContainer.java:624) at org.jboss.ejb.Container.invoke(Container.java:873) at sun.reflect.GeneratedMethodAccessor71.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:141) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) at org.jboss.mx.server.Invocation.invoke(Invocation.java:72) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:245) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:644) at org.jboss.invocation.jrmp.server.JRMPInvoker$MBeanServerAction.invoke(JRMPInvoker.java:805) at org.jboss.invocation.jrmp.server.JRMPInvoker.invoke(JRMPInvoker.java:406) at sun.reflect.GeneratedMethodAccessor70.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at sun.rmi.server.UnicastServerRef.dispatch(Unknown Source) at sun.rmi.transport.Transport$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.handleMessages(Unknown Source) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(Unknown Source) at java.lang.Thread.run(Unknown Source) ********************************************** I tried to search in the forums about this exception but didnt got much help besides synchronizing the EJB call. I dont want to show this error to the user and also, i dont want this error to come on Jboss console. Is it possible to find a solution without touching the EJB code? For the GUI part i am using Swings. I am strucked in this problem for long. It would be really great if someone suggests some solution.
