    Strange exception that only occurs the first time i call a WS operation

    When i call any WS operation from a J2ME client i get this strange exception:
    java.rmi.MarshalException: Unexpected Exception : unexpected end of stream

    The thing is, the WS receives the info i send, but the client doesn't receive the response. And even more wierd is that this only happens the first time, if i run the client again, it's all ok. I tried using J2SE and that works fine.

    I can pass whatever data to whatever WS operation, it's the same story.

    This is my J2ME code:
    Code:
    public void startApp() {
        try {
            pack.WSService_Stub service = new pack.WSService_Stub();
            boolean result = service.anyOperation();
            System.out.println(result);
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

    Unhappy Re: Strange exception that only occurs the first time i call a WS operation

    Hi,

    Did you manage to find a solution for this problem?
    I have the same problem calling a web service. It occurs only invoking one method,
    which returns an array of objects.
    When calling simples methods, it works.


    Cheers,
    Vladdy

    No, but i only get this exception when i run the emulator. On the actual device it works fine.

    I always try the operation twice

    Re: Strange exception that only occurs the first time i call a WS operation

    It looks to be some issue with your emulator or internet/server access, try to run it on some other emulator on some other system or try to check the web services accessibility from your computer via some desktop test tools..
