I am working on the Spring4.1.6 release. I have deployed my Webapplication named SpringMVCTest on Tomcat 7.0. I am getting the below exception on the tomcat startup. Below are the spring configuration file details.

But I don't understand one thing why I am still getting the below exception? As per the logs why it is still trying to look for the applicationContext.xml in the WEB-INF directory? Please help me on this issue and do let me know if any other information is required to resolve the issue.

I am completely new to Spring (MVC) and Hibernate and I am trying to learn it.
I made up the following authentication scenario to practice but I am not having much luck getting it to work.
Scenario:
I have an HTML form (homepageForm.jsp) that sends username and password to HomeController.
The HomeController gets the form parameters (username/password) and compares the form params to username & password retrieved from a database.
If there's a match, the user will be presented with the dashboard.jsp. If there's a mismatch, the error.jsp will be loaded instead.
The information from the db is retrieved by the "UserRetrievalService".
I am getting the following error:
:::: ERROR
type Exception report
message Request processing failed; nested exception is java.lang.NullPointerException
description The server encountered an internal error that prevented it from fulfilling this request.

I suspect it's related to the way the servlet.xml is referenced.
The line 91 in the HomeController is this one:
User user = userRetrievalService.getUser();
or perhaps I am using the #Autowired incorrectly.
Could anyone please give me some tips how to resolve this?
Thank you!

Your UserRetrievalService not properly injected.
You can use #Autowired or Constructor/Setter injection. In your case you used setter injection but not in a proper way
It should be like
private UserRetrievalService userRetrievalService;
#Autowired
public UserRetrievalService setUserRetrievalService(UserRetrievalService userRetrievalService) {
this.userRetrievalService = userRetrievalService;
}
Suggestion regarding hibernate configuraion.
You need keep hibernate.cfg.xml under classpath
As yours is maven project, the ideal place would be /src/main/resources/
Please refer to https://stackoverflow.com/a/29352557/7063373 for more clarity.
According to the Javadoc for Autowired, the annotation can be used on "a constructor, field, setter method or config method". In HomeController put Autowired annotation in service field.
#Autowired
private UserRetrievalService userRetrievalService;

Finally i found the solution is that , after adding .action to the action value.
it is working fine.
<s:form action="invoke.action">
<s:textfield name="name" label="UserName"></s:textfield><br>
<s:password name="password" label="Password"></s:password><br>
<s:submit value="GO"></s:submit>

In the above program, Whenever I go to http://localhost:8080/SpringRegister/index.htm, I always gets this error
Error:
neither bindingresult nor plain target object for bean 'userForm' available as request attribute
What is wrong with the code?
When you hit the http://localhost:8080/SpringRegister/index.htm from browser, Your request is handled by ParameterizableViewController which does not set the model attribute (userForm) and forwards to index.jsp, the index.jsp's form tag expects the model attribute userForm <form:form action="${pageContext.request.contextPath}/register" method="POST" modelAttribute="userForm"> , which is not available. that why the error. To resolve this you can create your own conrtoller which handles your http://localhost:8080/SpringRegister/index.htm URL,
ModelAndView modelAndView = new ModelAndView("your view name");
model.addAttribute("userForm", new User());
configure that controller instead of class="org.springframework.web.servlet.mvc.ParameterizableViewController" in your servlet xml. Hope this helps.
You need to Change in Controller To bind userForm with Bean ----
Jsp Form --
<form:form action="userAction" modelAttribute="userForm " class="form-search" role="form">
Controller --
#RequestMapping (value = "/userAction")
public ModelAndView checkFeasibility(#ModelAttribute("userForm ")User userForm)
{
// Any Action
model.addObject("userForm",userForm);
return model;
}
In order to Bind userForm modelAttribute of form with User Bean.
I am working with Spring and I have a problem with a bean, here is my code:

}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
}
in this page collaborateur.xhtml i Can't display data from my DATABASE collaborateur.xhtml:
<h:dataTable value="#{CollaborateurBean.getLis()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
When I test the collaborateurBo i display data from my DATABASE. This is the code that gives data from database:
<h:dataTable value="#{collaborateurBo.getAllCollaborateur()}" var="item">
<h:column>
<h:outputText value="#{item.nom}" />
</h:column>
<h:column>
<h:outputText value="#{item.prenom}" />
</h:column>
</h:dataTable>
This means that the problem is in the Collaborateur bean not in collaborateurBo or CollaborateurDao.
Here my configurations :

My Code is working well but it does not displays error messages in <form:errors />.
please help me.
The third parameter to ValidationUtils.rejectIfEmpty is an error code. It should be a key to the actual message in your resource bundle. I don't know how it behaves if it can't find a value. You should change it to use a key, and optionally set a default message. See the api.
You need to register your validator with the controller in which you want to use it. See: http://static.springsource.org/spring/docs/3.0.0.RC3/reference/html/ch05s07.html#validation.mvc
