Hello,

I am running Hibernate 2.1.1, Struts, and MySQL 1.4 database for my web application.

Here is a little piece of the Struts-config.xml file:
<action
path="/login"
type="com.tjgrp.guava.timesheet.LoginAction"
scope="request"
name="loginForm"
input="/login.jsp">
<forward name="success" path="/Welcome.jsp" redirect="true" />
<forward name="failure" path="/login.jsp" redirect="true" />
</action>

The problem I am having is that somehow 'success' never happens. (I deployed the application and checked). It also seems that in the Action class (loginAction) , something is not working as it should. Could you tell me what I am doing wrong?


public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
ActionForward forward = null;
LoginForm loginform = (LoginForm) form;

String password = loginform.getPassword();
String identifier = loginform.getIdentifier();

try {
Context ctx = new InitialContext();
SessionFactory sf = (SessionFactory) ctx.lookup(
"guava:/hibernate/SessionFactory");
Session session = sessionFactory.openSession();

String query =
"select guavauser from com.tjgrp.guava.data.GuavaUser guavauser " +
"where guavauser.password = :password and " +
"guavauser.identifier = :identifier";

Query q = session.createQuery(query);
q.setParameter("identifier", identifier, Hibernate.STRING);
q.setParameter("password", password, Hibernate.STRING);

GuavaUser gUser = (GuavaUser) q.uniqueResult();

request.setAttribute("objId", gUser);
forward = mapping.findForward("success");
loginform.clear();
session.close();

} catch (NamingException e) {
System.err.println("Naming Exception" + e.getMessage());
throw new RuntimeException(e);

} catch (HibernateException e) {
System.err.println("Hibernate Exception" + e.getMessage());
throw new RuntimeException(e);

} finally {
return forward;
}
}

Here is the stack trace:

Could the warning I am getting at the end be the problem?

Some feedback is really appreciated..

try to comment some lines or debug (the best way) if you're using eclipse or jbuilder.


pretty sure forward = mapping.findForward("success"); is not reached

"pretty sure forward = mapping.findForward("success"); is not reached"


Yes I know it is not reached.... I debugged the code but I don't know why it is never reached..... Bottom line: I want to know whether I am writing the LoginAction class in the correct way to handle Hibernate. There is something not functioning inside the try-catch block..
Could it be something in the HibernatePlugIn.java file perhaps? Here it is for reference. Thank again.

Please disregard my question... I figured out where I was going wrong ;-)

Thanks for your help

tell where was the error, it could be usefull for other users

Well.. its too embarrasing to say :D


Instead of writing
SessionFactory sessionFactory = (SessionFactory) ctx.lookup(
"blah:/hibernate/SessionFactory");
Session session = sessionFactory.openSession();


I did:
SessionFactory sf = (SessionFactory) ctx.lookup(
"blah:/hibernate/SessionFactory");
Session session = sessionFactory.openSession();

hmm... so you see... its a no brainer ...

:)

Where is the solution?

Except You are using undeclared variable (how that works?) i can not see how this could solve Your problem?

sf!=sessionFactory
