I tried your configuration and I did not get your error. But I had to change something.

ViewResolver adds .jsp to your view. Therefore IMHO you have to change

  return new ModelAndView("/student.jsp", "SpringWeb", new Student());

to

  return new ModelAndView("student", "SpringWeb", new Student());

So, remove jsp and "/" in front of the student.

Then it worked for me. But, as I said, I did not get your mistake

Edit:

It seems to me that your exceptions specify a "bean name " command . I think you have a paperwork problem because the code you posted here does not match the exception.

Remove the commandName attribute from the form tag, the modelAttribute attribute modelAttribute enough:

 <form:form modelAttribute="SpringWeb" method="POST" action="/HelloWeb/addStudent" >

After reading this article, this suggests that this is not a solution to your problem, but in any case you do not need to specify them twice.

The jsp location accessed by the /student call is

 /WEB-INF/JSP//student.jsp.jsp

Change the configuration to match the corresponding URL.
