Thank you very much - indeed that fixed my POJO problem. Now, I'm down to one last hurdle. Hopefully after this I'll be off and running. I did buy the Rough Cuts book by the way but I haven't seen this in there yet.
Question is - What is the proper way to inject the GreeterBean into my Stateless LoginAction class. I'll list the code here:
| package com.clooster.web.ejb.session;
|
| import java.util.List;
|
| import javax.ejb.Stateless;
| import javax.faces.application.FacesMessage;
| import javax.faces.context.FacesContext;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
|
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.contexts.Context;
| import org.jboss.seam.core.FacesMessages;
| import org.jboss.seam.log.Log;
|
| import com.clooster.web.ejb.entity.ClUsers;
|
| @Stateless
| @Name("login")
| public class LoginAction implements Login
| {
|
| @Logger
| private Log log;
|
| @In
| FacesMessages facesMessages;
|
| @In
| GreeterBean greeter;
|
| @PersistenceContext
| private EntityManager em;
|
| @In
| private transient Context sessionContext;
|
| @In
| private transient FacesContext facesContext;
|
| // seam-gen method
| public String login()
| {
| log.info("Entered LoginAction login");
| log.info("Greeter is " + greeter);
|
| List<ClUsers> results = em.createQuery(
| "from ClUsers where cloosterid=:cloosterid and password=:password")
| .setParameter("cloosterid", greeter.getName())
| .setParameter("password",
| greeter.getPassword().getBytes())
| .getResultList();
|
| if (results.size() == 0)
| {
| facesContext.addMessage(null, new FacesMessage(
| "Invalid login"));
|
| return "login";
| }
| else
| {
| ClUsers user = results.get(0);
| sessionContext.set("loggedIn", true);
| sessionContext.set("User", user);
|
| log.info("Logged In");
| return "main";
| }
| }
| }
|
When I remove the @In annotation on the GreeterBean, it is null after submitting the form. When I include the @In annotation I get the following error.
