Re: OSUser and Hibernate: couple of questions

Thanks!

I tried setting up a test with your directions, but I'm getting the
following error:

java.lang.NullPointerException
	at com.opensymphony.module.propertyset.hibernate.HibernatePropertySetDAOImpl.setImpl(HibernatePropertySetDAOImpl.java:42)
	at com.opensymphony.module.propertyset.hibernate.HibernatePropertySet.setImpl(HibernatePropertySet.java:156)
	at com.opensymphony.module.propertyset.AbstractPropertySet.set(AbstractPropertySet.java:565)
	at com.opensymphony.module.propertyset.AbstractPropertySet.setString(AbstractPropertySet.java:363)
	at com.opensymphony.user.User.setEmail(User.java:61)
	at org.mathesis.test.OSUserTest.doGet(OSUserTest.java:37)

This is my code:

/*
 * Created on 29-sep-2003
 *
 * To change the template for this generated file go to
 * Window - Preferences - Java - Code Generation - Code and Comments
 */
package org.mathesis.test;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.opensymphony.module.propertyset.PropertySet;
import com.opensymphony.user.User;
import com.opensymphony.user.UserManager;

/**
 * @author ilja
 *
 * To change the template for this generated type comment go to
 * Window - Preferences - Java - Code Generation - Code and Comments
 */
public class OSUserTest extends HttpServlet
{
	public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
	{
		UserManager um = UserManager.getInstance();
		PrintWriter out = response.getWriter();
		
		try
		{
			User u = um.getUser("ilja");
			u.setEmail("[email protected]");
			u.setPassword("arnomarie");
			
			PropertySet userProperties = u.getPropertySet();
			
			userProperties.setString("first-name", "Ilja");
			userProperties.setString("last-name", "My-lastname");
		}
		catch (Exception e)
		{	
			e.printStackTrace(out);
		}
	}
}

The error occurs on the line u.setEmail("[email protected]");
The user does exist, I tested it with out.println(u.getUsername());

This is the original cause of the error in HibernatePropertySetDAOImpl:

    public void setImpl(PropertySetItem item) {
        Session session = null;

        try {
---->            session = this.sessionFactory.openSession();
