Java EE (Java Enterprise Edition) General Discussion

Hello!

Some information before: I am working on an enterprise project consisting of an EJB and an application client. Now I want to add an web client, but every time i want to call an EJB, the web application fails with the following message:

object is not an instance of declaring class

The application client & EJB works fine. The EJB is coded as follows:

@Remote
public interface EJBTestRemote {
    // interface stuff [...]
}

@Local
public interface EJBTestLocal {
    // interface stuff [...]
}

@Stateless
public class EJBTestBean implements EJBTestRemote, EJBTestLocal {
    // implementation stuff [...]
}

In the web app I call the EJB as follows (the error occurs here):

public class EJBTestWelcome extends AbstractPageBean {
    @EJB
    private EJBTestRemote ejbTestBean;

    // implementation stuff [...]

What does this error mean and what can be done to solve this issue?

My environment: SJAS 9.1, Netbean 6.0

Thanks in advance!
