NotSerializableException

[Tal Tal]

Hello
I'm having problemss moving my project from jdk 1.3 to jdk 1.4.
when i try to run my project using jdk1.4 it throws a NotSerializableException...the weird thing about it is that when i run the project using jdk1.3 it dosent throw the NotSerializableException...
i tried to rebuild it over and over again, but it didnt work,
anyone knows what can cause it?
thanks

Why don't you post the code where the exception is being thrown and the stack trace from the exception and maybe we can figure this out.

ok here is the stack trace

as you can see the problem is in the loginServer Stub, thats the code

public erp.framework.iface.remote.ServiceFactory login(erp.services.authentication.iface.UserCredentials $param_UserCredentials_1)
throws erp.framework.iface.remote.InternalServerException, erp.services.authentication.iface.AuthenticationFailedException, java.rmi.RemoteException
    {
try {
it throws the exception here ---> Object $result = ref.invoke(this, $method_login_0, new java.lang.Object[] {$param_UserCredentials_1}, 8982913166179385719L);

    return ((erp.framework.iface.remote.ServiceFactory) $result);
} catch (java.lang.RuntimeException e) {
    throw e;
} catch (java.rmi.RemoteException e) {
    throw e;
} catch (erp.framework.iface.remote.InternalServerException e) {
    throw e;
} catch (erp.services.authentication.iface.AuthenticationFailedException e) {
    throw e;
} catch (java.lang.Exception e) {
    throw new java.rmi.UnexpectedException("undeclared checked exception", e);
}
    }

and thats the class before the loginserver stub:

result = loginService.login(ucr);
