Yes is the part of my context file:
</bean>
<bean id="userService" class="service.UserServiceImp">
<property name="userDao">
<ref bean="userDao"></ref>
</property>
</bean>
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="messages" />
</bean>
<bean id="loginAction" class="action.LoginAction">
<property name="userService">
<ref bean="userService"></ref>
</property>
<property name="messageSource" ref="messageSource"/>
</bean>
I have tried to figure out the problem for hours no luck...

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 :)
