We are getting a Null Pointer Exception in an MDB that is listening for emails.
It appears that the Seam components are not being properly injected. We get errors when we attempt to use @Logger. We have changed these for the time being to System.out.printlns. Our service EJB components are not getting injected either. Our environment is Seam 1.1.7RC1, JBoss 4.0.5. The mail-ra.rar file has been placed in the server\default\deploy folder. The following is our MDB that is throwing the NPEs: | package us.crimnet.iss.listeners; | | import javax.ejb.ActivationConfigProperty; | import javax.ejb.MessageDriven; | import javax.ejb.Stateless; | import javax.mail.Message; | | import org.jboss.annotation.ejb.ResourceAdapter; | import org.jboss.mail.MailException; | | import org.jboss.resource.adapter.mail.inflow.MailListener; | import org.jboss.seam.Component; | import org.jboss.seam.annotations.In; | import org.jboss.seam.annotations.Name; | import org.jboss.seam.annotations.Scope; | import org.jboss.seam.ScopeType; | | import us.crimnet.iss.services.HistoryManagement; | import us.crimnet.iss.services.impl.HistoryManagementImpl; | | @MessageDriven(activationConfig={ | @ActivationConfigProperty(propertyName="mailServer", propertyValue="domain.com"), | @ActivationConfigProperty(propertyName="mailFolder", propertyValue="INBOX"), | @ActivationConfigProperty(propertyName="storeProtocol", propertyValue="pop3"), | @ActivationConfigProperty(propertyName="userName", propertyValue="uid"), | @ActivationConfigProperty(propertyName="password", propertyValue="pwd") | }) | | @ResourceAdapter("mail-ra.rar") | @Name("requestEmailListener") | | public class RequestEmailListener implements MailListener { | | @In(create=true) | private HistoryManagement historyManagement; | | public void onMessage(Message message) { | System.out.println("Can we inject the @Logger here???"); | System.out.println("RequestEmailListener.onMessage()"); | try { | Long id = Long.parseLong(message.getSubject()); | System.out.println("History id [" + id + "]"); | //TODO : dj : The following line threw an NPE | // was it not properly injected by Seam? | historyManagement.sendRequest(id); | | System.out.println("back from HistoryManagement"); | } catch (Exception e) { | e.printStackTrace(); | } | } | } | Any suggestions as to what the causing the Seam Components not to be injected or initialized? Thanks!
