Problem migration from WF10 to WF12: NPE on EJB injection on Servlet
Hello,
I'm trying to migrate an EAR application working on WF10 to WF12.
I've a servlet that inject a Singleton EJB:
public class Controller extends HttpServlet {
/**
* Generated serial version ID
*/
private static final long serialVersionUID = 8384479283247737172L;
@Inject
private Logger log;
@EJB
private ErrorManager errorManager;
private static final String IS_RESULT_BEAN_PARAMETER = "isResultBean";
public static final String OPC_PDF = "PDF";
public static final String OPC_PDF_DIRECTO = "PDFR";
public static final String OPC_EXCEL = "EXCEL";
public static final String OPC_JASPER = "JASPER";
public static final String OPC_SISTEMA = "OP";
public static final String OPC_XML = "XML";
public static final String OPC_JSON = "JSON";
public static final String OPC_EMAIL = "EMAIL";
@EJB
private ParameterManager param;
This is the header of the EJB:
@Singleton
@Local(value=IParameterManagerLocal.class)
public class ParameterManager implements IParameterManagerLocal {
@Inject
private Logger log;
@PersistenceContext
private EntityManager em;
And I've a NPE on init method:
@Override
public void init() throws ServletException {
super.init();
if (log.isInfoEnabled()) {
log.info("INIT del CONTROLLER");
}
// Carga inicial de los parametros de la aplicacion
param.loadParameters();
When it launchs param.loadParameters(), param is null.
I've this stachtrace:

I need to do something to make it work on WF12?
Lot of thanks,
Marcial
