<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For a while we had 2 instances of 4.0.5 running where instance A was calling EJB services of instance B. 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. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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 </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>java.lang.Exception: Can not make remoting client invocation due to</p><p>not being connected to server.</p><p>       org.jboss.remoting.Client.invoke(Client.java:1729)</p><p>       org.jboss.remoting.Client.invoke(Client.java:629)</p><p>       org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke(InvokeRemoteInterceptor.java:55)</p><p>       org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)</p><p>       org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:61)</p><p>       org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)</p><p>       org.jboss.aspects.security.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:53)</p><p>       org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)</p><p>       org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:77)</p><p>       org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102)</p><p>       org.jboss.ejb3.stateless.StatelessRemoteProxy.invoke(StatelessRemoteProxy.java:102)</p><p>       $Proxy351.searchForExperiments(Unknown Source)</p><p>       gov.nih.nci.caintegrator2.external.caarray.CaArrayUtils.getExperiment(CaArrayUtils.java:168)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>When I googled this I found a seemingly helpful thread speaking about</p><p>the new req in remoting 2.x that connect() be called before invoke()</p><p>and how this did not use to be required in remoting 1.x</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>here is the thread: <a class="jive-link-message-small" href="http://community.jboss.org/message/368917#368917" target="_blank">http://community.jboss.org/message/368917#368917</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>but I actually can't figure out how we are doing this since</p><p>we aren't writing a client and invoking from the container.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>also, fyi, as a test upgrading instance B to 5.1 as well... everything works fine.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Any help would be greatly appreciated.</p></div>
