Problem registering Callback applet in weblogic 8.1 RMI

Posted on 2004-11-22

I am using a signed applet which is loaded from the web application. This applet is used to communicate to the weblogic RMI Sever. (both the web application and RMI are in same server and removed the applet and tried with normal java client, it fails in both the cases and giving the same exception)

This is my code to export and register the applet.

String serverName = "WLRMISERVER";
mRmiServer = (WLRMIServer) ctx.lookup(serverName);
CTIAppletCallback callback = new CTICommunicationApplet();//Just for Testing
System.out.println("Exporting Object");
RemoteStub stub = UnicastRemoteObject.exportObject(callback); <b> (Fails here, if stubs are not there)</b>
System.out.println("Object Exported ::"+stub);
mRmiServer.registerCallback((CTIAppletCallback)stub); <b>(Fails here, if i generate the stubs using JRMP)</b>
System.out.println("Call back registered");

I can able to call the remote functions of the RMI Server, but while registering the applet for callback, I am getting the following exception.

<b>//If stubs are generated by JRMP otherwise StubNotFoundException
Exporting Object
Object Exported ::com.ehsn.cti.applet.CTICommunicationApplet_Stub[RemoteStub [ref: endpoint:[](local),objID:[0]]]]

Hi Vikram,

To execute the client application, it needs the weblogic.jar.

Weblogic.jar is 30 MB in size, wlclient.jar is not having all the files for RMI.

Is there any client jar file provided by weblogic for RMI Clients?.

Thanks and Regards,
