Hello, I am Working in EJB, and using Java2 Enterprise Edition, using j2sdkee1.2.1 as a deployment tool, I am getting a problem that when I am deploying my application on Windows 9.x platform it is deploying fine, but when I am deploying my application on Winnt Platform then at the last step("Deployment time") it gives me error. which the below....... ("There Was a Deployment Error java.rmi.ServerException: Remote Error Occur in Server thread; Nested Exception is: Java.rmi.RemoteException: Error Saving/Opening") This error is confusing me, why is this, I am developing a stateless Bean, and making an .ear file process is simple, but this error teases... Can you tell me about that, Syed Usman Shaukat Ali
