We upgraded instance A to 5.1 and at that point started getting the InvokationException with the serial number mismatch between classes in the 2 different versions of jbossas-client.jar. After doing a little research I started bringing up instance A with the property -Djboss.remoting.pre_2_0_compatible=true and the error I started seeing was java.lang.Exception: Can not make remoting client invocation due to not being connected to server.        org.jboss.remoting.Client.invoke(Client.java:1729)        org.jboss.remoting.Client.invoke(Client.java:629)        org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke(InvokeRemoteInterceptor.java:55)        org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)        org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:61)        org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)        org.jboss.aspects.security.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:53)        org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)        org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:77)        org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)        org.jboss.ejb3.stateless.StatelessRemoteProxy.invoke(StatelessRemoteProxy.java:102)        $Proxy351.searchForExperiments(Unknown Source)        gov.nih.nci.caintegrator2.external.caarray.CaArrayUtils.getExperiment(CaArrayUtils.java:168) When I googled this I found a seemingly helpful thread speaking about the new req in remoting 2.x that connect() be called before invoke() and how this did not use to be required in remoting 1.x here is the thread: http://community.jboss.org/message/368917#368917 http://community.jboss.org/message/368917#368917 but I actually can't figure out how we are doing this since we aren't writing a client and invoking from the container. also, fyi, as a test upgrading instance B to 5.1 as well... everything works fine. Any help would be greatly appreciated. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/645472#645472] Start a new discussion in JBoss Remoting at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
