Hi All, I am using the JDK1.2 on my RedHat Development system with very good results. The Server RMI application works very nicely on RedHat. But when taking the jar over to an NT system the server receives the following Exception: ----------------------------------------------------- cfs Exception: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshallng arguments; nested exception is: java.lang.ClassNotFoundException: irsw.cf.server.cfs_Stub ----------------------------------------------------- I have verified that the class "irsw.cf.server.cfs_Stub" is in the jar. I have extracted the class files out of the jar with the same Exception. This class file is one of the last classes loaded; in other words, the application is finding all the other classes just fine. Does anyone have any idea why this is happening??? Is rmic a native thang??? Thanks in advance, howeeeee ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
