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

[Infernal01]

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:

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();
    }
}

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,

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

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..
