问题
I try to deploy an application which uses EJB on weblogic 10.3. I use the framework seam 2.2.0
I created an EJB project and en EAR project with workshop.
When I compile the project, I get this error:
weblogic.ejb.container.compliance.ComplianceException: No business interface, component interface or web service endpoint interface found for Session Bean Authenticator
Here is the bean code:
import javax.ejb.Local;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.contexts.SessionContext;
import org.jboss.seam.faces.FacesMessages;
import org.jboss.seam.faces.Redirect;
import org.jboss.seam.log.Log;
import org.jboss.seam.security.Credentials;
import org.jboss.seam.security.Identity;
import org.jboss.seam.security.crypto.BinTools;
import org.jboss.seam.security.management.IdentityManager;
import org.jboss.seam.security.management.JpaIdentityStore;
@Stateless
@Local
@Name("authenticator")
public class Authenticator {
}
And here is the exception:
weblogic.ejb.container.compliance.ComplianceException: No business interface, component interface or web service endpoint interface found for Session Bean Authenticator

I don't understand my error.
Thanks for your help.
回答1:
This happens because Weblogic is looking for an interface that Authenticator implements.
Change to:
@Stateless
@Name("authenticator")
public class Authenticator implements AuthenticatorLocal {
@Override
public void oneMethod()
{
//enter code here
}
}
@Local
public interface AuthenticatorLocal {
void oneMethod();
}
Note: the interface must have at least one overridden method, otherwise you'll get the same error again.
回答2:
Happens because weblogic will search for an interface for EJB Local service:
@Stateless
@Local
@Name("authenticator")
public class Authenticator {
}
if you implement an interface, and provide it to EJB this problem is solved. Like this:
@Stateless
@Local(IAuthenticator.class)
@Name("authenticator")
public class Authenticator implements IAuthenticator{
//your business logic
}
public interface IAuthenticator {
// interface
}
