[jboss-user] [Installation, Configuration & DEPLOYMENT] - Class not found error after start up

I am getting the exception below when my jboss app recieves a remote call from a tomcat application. I posted here because I think something is not starting up right. I should say that this app was starting up and working correctly before we deployed it in a clustered JBoss environment. I am running JBoss 4.2.1.GA with Java 5. We are using Spring and EJB3. I did set up HA-JMS for the servers as well. I am confused as to the problem because the MarshalledValue is part of the same jar as SimpleMetaData. Is ther something else I should be doing at startup? | java.lang.NoClassDefFoundError: org/jboss/aop/util/MarshalledValue | 16:44:42,360 ERROR [STDERR] at org.jboss.aop.metadata.SimpleMetaData.readExternal(SimpleMetaData.java:251) | 16:44:42,360 ERROR [STDERR] at java.io.ObjectInputStream.readExternalData(ObjectInputStream.java:1755) | 16:44:42,360 ERROR [STDERR] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1717) | 16:44:42,360 ERROR [STDERR] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1305) | 16:44:42,360 ERROR [STDERR] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) | 16:44:42,361 ERROR [STDERR] at org.jboss.aop.joinpoint.MethodInvocation.readExternal(MethodInvocation.java:328) | 16:44:42,361 ERROR [STDERR] at java.io.ObjectInputStream.readExternalData(ObjectInputStream.java:1755) | 16:44:42,361 ERROR [STDERR] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1717) | 16:44:42,361 ERROR [STDERR] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1305) | 16:44:42,361 ERROR [STDERR] at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1908) | 16:44:42,362 ERROR [STDERR] at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1832) | 16:44:42,362 ERROR [STDERR] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1719) | 16:44:42,362 ERROR [STDERR] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1305) | 16:44:42,362 ERROR [STDERR] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) | 16:44:42,362 ERROR [STDERR] at org.jboss.remoting.serialization.impl.java.JavaSerializationManager.receiveObjectVersion2_2(JavaSerializationManager.java:239) | 16:44:42,362 ERROR [STDERR] at org.jboss.remoting.serialization.impl.java.JavaSerializationManager.receiveObject(JavaSerializationManager.java:133) | 16:44:42,363 ERROR [STDERR] at org.jboss.remoting.marshal.serializable.SerializableUnMarshaller.read(SerializableUnMarshaller.java:120) | 16:44:42,363 ERROR [STDERR] at org.jboss.remoting.transport.socket.ServerThread.versionedRead(ServerThread.java:650) | 16:44:42,363 ERROR [STDERR] at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:530) | 16:44:42,363 ERROR [STDERR] at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:369) | 16:44:42,363 ERROR [STDERR] at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:165) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4202295#...
