[jboss-user] [JBoss Portal] - Re: How to get error messages on Login Failed

I realise this is a late reply, but hopefully someone will find this answer useful.

Step 1) override the getUserStatus method in your custom loginModule
ie.


  |     @Override
  |     protected UserStatus getUserStatus(String inputPassword){
  |         MyUserVO user=getUserService().getUserByName(getUsernameAndPassword()[0]);
  |         if (!myLoginCheck(user)){
  |           return MyUserStatus.MY_ERROR_MESSAGE_1;
  |         }
  |         return super.getUserStatus(inputPassword);
  |     }
  | 

Step 2) pseudo extend UserStatus (the constructor is actually private so you need to reflect it).  note: getUserStatus is called in the Login method if the login is successful - so remember to put any logic for a failure is the Abort method and successful login code in the Commit method
ie.

  | public class MyUserStatus {
  |     public static UserStatus MY_ERROR_MESSAGE_1=naughtyCallOfPrivateConstructor(33945);
  |     private static UserStatus naughtyCallOfPrivateConstructor(int i){
  |         try{
  |             Class<?> c = Class.forName(UserStatus.class.getCanonicalName());
  |             Constructor[] allConstructors = c.getDeclaredConstructors();
  |             for (Constructor ctor : allConstructors) {
  |                 ctor.setAccessible(true);
  |                 UserStatus res=(UserStatus)ctor.newInstance(i);
  |                 ctor.setAccessible(false); //return it just in case this causes an issue elsewhere
  |                 return res;
  |             }
  |         }catch(IllegalAccessException e){
  |             e.printStackTrace();
  |         }catch(Exception e){
  |             e.printStackTrace();
  |         }
  |         return null;
  |     }
  | }
  | 

Step 3) change your portal-server.war/login.jsp to use the new MyUserStatus - ie.

  |  else if (MyUserStatus.MY_ERROR_MESSAGE_1.equals(request.getAttribute("org.jboss.portal.userStatus"))){
  |                    out.println(rb.getString("ACCOUNT_MY_ERROR_MESSAGE_1"));
  |                }
  | 

and don't forget to put the error message text in the resources file (Resource.properties in conf/bundles/)

hope this helps,
