You were on the right track before, you just want the following in your
class -
-snippet
private UserService userService;
public void setUserService(UserService userService) {
this.userService = userService;
}
- end snippet
I am curious if it's 'userService' that is null... This would mean
that your action isn't being wired with the service from Spring. I
snipped all the previous messages from this email, so i can't look
through it for you, but I will say that this sort of thing is
generally a simple property misspelling or some other detail (decimal
point? I always mess up some mundane detail). If it's username that is
null, you might want to check that your form is properly setup in your
JSP.

MY dao is not using hibernate template but sessuin factory I have changed it
to this:
bean id=userDao class=dao.UserDaoImpl
property name=HibernateTemplate
ref bean=HibernateTemplate/ref
/property
/bean
Regarding the case consistency I have the table field userName, and the
variable username, did you see any typing mistake.
I have run the example and seems that the problem is that hibernate template
is not define how can i define it please I dont know the syntax?
Here is the error:
SEVERE: Exception sending context initialized event to listener instance of

the UserDaoImpl class refers to hibernateTemplate in multiple statements most
notably
public User getuser(String password) {
return (User)getHibernateTemplate().find(from User as u where
u.password = ?, password).get(0);
you'll need to define the hibernateTemplate bean which ref bean can refer to
later on
bean id=hibernateTemplate
class=org.springframework.orm.hibernate.HibernateTemplate
property name=sessionFactory
ref bean=sessionFactory/
/property
/bean

This is the definition of my session factory, hibernate properties and data
source :
bean id=dataSource
class=org.springframework.jdbc.datasource.DriverManagerDataSource
property name=driverClassName value=com.mysql.jdbc.Driver/
property name=url value=jdbc:mysql://localhost:3306/sshdemo/
property name=username value=root/
property name=password value=/
/bean
bean id=sessionFactory
class=org.springframework.orm.hibernate3.LocalSessionFactoryBean
property name=dataSource ref=dataSource/
property name=mappingResources
list
valuepo/user.hbm.xml/value
/list
/property
property name=hibernateProperties
valuehibernate.dialect=org.hibernate.dialect.MySQLDialect/value
/property
/bean
MY dao is not using hibernate template but sessuin factory I have changed it
to this:
bean id=userDao class=dao.UserDaoImpl
property name=HibernateTemplate
ref bean=HibernateTemplate/ref
/property
/bean
Regarding the case consistency I have the table field userName, and the
variable username, did you see any typing mistake.
I have run the example and seems that the problem is that hibernate template
is not define how can i define it please I don’t know the syntax?
Here is the error:
SEVERE: Exception sending context initialized event to listener instance of
class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'userDao' defined in ServletContext resource
[/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean
'HibernateTemplate' while setting bean property 'HibernateTemplate'; nested
exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean
named 'HibernateTemplate' is defined
Thanks for your help

Might be true, but it also demonstrates why method chaining can be
troublesome, we don't know if the NPE is coming from there or from the

line into multiple lines. It will give you an indication whether you

cannot do a get(0) on a null result
public User getUser(String userName) {
return (User)getHibernateTemplate().find(from User as u where
u.name = ?, userName).get(0);
}public interface UserService cannot be referenced directly so best to use
your impl class
change User usr= userService.getUser(username);
to User usr=userServiceImp.getUser(username);
traditionally implementation classes are named ClassNameImpl instead of
ClassNameImp
avoid static references such as userService.getUser(username);
better to
getUserService().getUser(username);
//which means the *Action will need accessor method getUserService defined
e.g.
public UserServiceImp getUserService() {
return userService;
}

userService is a UserServiceImp instance-- UserServiceimp userService.
You were on the right track before, you just want the following in your class -
-snippet
private UserService userService;
public void setUserService(UserService userService) {
this.userService = userService;
}
- end snippet
I am curious if it's 'userService' that is null... This would mean
that your action isn't being wired with the service from Spring. I
snipped all the previous messages from this email, so i can't look
through it for you, but I will say that this sort of thing is
generally a simple property misspelling or some other detail (decimal
point? I always mess up some mundane detail). If it's username that is
null, you might want to check that your form is properly setup in your
JSP.

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 :)

Looks like you have a NPE at line 31 in LoginAction. What line is
that? Which references could have been null?

RE: Hibernate3+Spring2.5+Struts2
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.

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

Your UserServiceImp userService was instantiated but never initialized in your

In many programming languages, all variables (fields) have to be initialized
before use with exception of primitive types (byte, short, etc - NOTE: String
is null by default- they will have a default value). Your custom class
UserServiceImp was instantiated with userService but never initialized. So
when you try to do userService.getUser() in the execute() method of your
LoginAction, you'll get the NPE as seen. I suggest you spend some time and go
through this http://java.sun.com/docs/books/tutorial/ . Your current problem
