Thanks for your reply, well this is the link to the code I am trying to run it is in two parts in the same blog that will be easier for you to locate the problem.
http://blogs.sun.com/LiYuanxin/entry/integrating_struts2_0_spring2_5 The problem is in this line in my LoginAction : User usr = userService.getUser(username); I am sorry if I am not clear but it's because I didn't get the code. -----Original Message----- From: Dave Newton [mailto:newton.d...@yahoo.com] Sent: 19 August 2009 15:18 To: Struts Users Mailing List Subject: Re: Hibernate3+Spring2.5+Struts2 Is there a user service injected into your action? If so, does the service return a user? (Are you typing your program in via SMS? It seems like everything is named reasonable except for "usr" :( It's really difficult for us to help when we don't know the line that's causing the error: *you* know that, and should either tell us, or provide a means for us to figure it out. The more relevant information you can provide the easier it is for us to help :) Dave Zied Bejaoui wrote: > Well the problem is that this is my first example with spring and hibernate > I have downloaded the example which should create a login application, now > as I said the table have an id a user name and a password. > Here is the line of the exception: > > User usr = userService.getUser(username); > > Here is the user service interface and class: > > package service; > import dao.UserDaoImpl; > import po.User; > /** > * > * @author ABIS1 > */ > public interface UserService { > void addUser(String userName, String password, int admin) throws > Exception; > > User getUser(long userId); > > User getUser(String userName); > > void setUserDao(UserDaoImpl userDao); > > } > > --------------------- > > package service; > import po.User; > > /** > * > * @author ABIS1 > */ > public class UserServiceImp implements UserService { > > private dao.UserDao userDao; > > public void addUser(String userName, String password, int admin) throws > Exception{ > po.User user = new User(); > > > user.setName(userName); > user.setPassword(password); > try > { > userDao.save(user); > } > catch(Exception err) > { > throw err; > } > } > public User getUser(long userId) > { > return userDao.getUser(userId); > } > > public void setUserDao(dao.UserDaoImpl userDao) { > this.userDao = userDao; > } > > public User getUser(String userName) { > return this.userDao.getUser(userName); > } > > } > > ----------------------- > > And the user dao interface and implementation: > > package dao; > import po.User; > > > /** > * > * @author ABIS1 > */ > public interface UserDao { > > void save(User user) throws Exception; > User getUser(long userId); > User getUser(String userName); > > } > > ------------- > > /* > * To change this template, choose Tools | Templates > * and open the template in the editor. > */ > > package dao; > > import po.*; > import dao.UserDao; > import org.springframework.orm.hibernate3.support.HibernateDaoSupport; > > /** > * > * @author ABIS1 > */ > public class UserDaoImpl extends HibernateDaoSupport implements UserDao { > > public void save(User user) throws Exception > { > try > { > getHibernateTemplate().save(user); > } > catch(Exception err) > { > throw err; > } > > } > > public User getUser(long userId) > { > return (User)getHibernateTemplate().get(User.class, userId); > } > > public User getUser(String userName) { > return (User)getHibernateTemplate().find("from User as u where > u.name = ?", userName).get(0); > } > > } > > > > > > -----Original Message----- > From: Nils-Helge Garli Hegvik [mailto:nil...@gmail.com] > Sent: 19 August 2009 13:05 > To: Struts Users Mailing List > Subject: Re: Hibernate3+Spring2.5+Struts2 > > java.lang.NullPointerException > at action.LoginAction.execute(LoginAction.java:31) > > Looks like you have a NPE at line 31 in LoginAction.
