Modifying Activator to implement javax.xml.ws.Provider

Change the Activator to extend org.eclipse.persistence.internal.dbws.ProviderHelper (NB - will show errors):

In order to correct the errors, the SimpleTable project needs to update its list of required bundles. Open the MANIFEST.MF file in the 'Plug-in Manifest Editor' and select the 'Dependencies' tab and add the following bundles:

The Activator needs to be annotated to support a (dynamic) Web services Endpoint:

public class Constants {
    //DBWS Properties
    public static final String TEST_PROJECT = 
    	"simpletable";
 
    //JAX-WS properties
    public static final String TEST_NAMESPACE = 
    	"urn:" + TEST_PROJECT;
    public static final String TEST_SERVICE = 
    	TEST_PROJECT + "Service";
    public static final String TEST_SERVICE_NAMESPACE = 
    	"urn:" + TEST_SERVICE;
    public static final String TEST_PORT = 
    	TEST_SERVICE + "Port";
    public static final String ENDPOINT_ADDRESS = 
    	"http://localhost:9999/" + TEST_PROJECT;
}
