I just installed JBoss 4.2.2 GA and was trying to test Beans using a client in Eclipse and getting error messages. On the server: java.io.EOFException at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:530) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:373) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:166) and from LOG: 2008-06-18 13:29:47,935 DEBUG [org.jboss.remoting.transport.socket.ServerThread] WorkerThread#0[127.0.0.1:1550] closing socketWrapper: ServerSocketWrapper[Socket[addr=/127.0.0.1,port=1550,localport=4446].18f7f27] 2008-06-18 13:29:47,935 DEBUG [org.jboss.remoting.transport.socket.ServerSocketWrapper] wrote CLOSING 2008-06-18 13:29:47,935 DEBUG [org.jboss.remoting.transport.socket.SocketWrapper] ServerSocketWrapper[Socket[addr=/127.0.0.1,port=1550,localport=4446].18f7f27] closing 2008-06-18 13:30:20,544 TRACE [org.jboss.remoting.transport.socket.SocketServerInvoker] passed through ServerSocketRefresh.release() 2008-06-18 13:30:20,544 TRACE [org.jboss.remoting.serialization.impl.java.JavaSerializationManager] Creating ObjectOutputStream 2008-06-18 13:30:20,544 TRACE [org.jboss.remoting.serialization.impl.java.JavaSerializationManager] Creating ObjectInputStreamWithClassLoader 2008-06-18 13:30:20,607 DEBUG [org.jboss.remoting.transport.socket.ClientSocketWrapper] reset timeout: 60000 2008-06-18 13:30:20,607 ERROR [org.jboss.remoting.transport.socket.ServerThread] Worker thread initialization failure In the console of Eclipse I when I run the client: (socket.SocketClientInvoker 293 ) Got marshalling exception, exiting java.io.OptionalDataException at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1310) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:339) at org.jboss.remoting.serialization.impl.java.JavaSerializationManager.receiveObject(JavaSerializationManager.java:128) at org.jboss.remoting.marshal.serializable.SerializableUnMarshaller.read(SerializableUnMarshaller.java:66) at org.jboss.invocation.unified.marshall.InvocationUnMarshaller.read(InvocationUnMarshaller.java:51) at org.jboss.remoting.transport.socket.SocketClientInvoker.transport(SocketClientInvoker.java:279) at org.jboss.remoting.RemoteClientInvoker.invoke(RemoteClientInvoker.java:143) at org.jboss.remoting.Client.invoke(Client.java:525) I am pointing to all of the jars on the jboss server in the build path of the project that I running the client in so that I am using the same exact jbossall-client.jar. Snippet from client: ejbHomeInterface = this.getHomeInterface( jndiName, _class ); interfaceImpl = ejbHomeInterface.getClass(); method = interfaceImpl.getMethod( CREATE, null ); Fails here on the invoke method: remoteInterface = method.invoke( ejbHomeInterface, null ); I am using jdk1.5.0_06...don't think that matters, does it? Not using EJB 3, this is part of a conversion from Weblogic 8.1 Any ideas....I've tried everything that I can think of.
