Spring MVC Restful App: how to redirect a form result to another page

I'm new to Spring MVC Restful. Suppose I have index.jsp which forwards user to a form page where user could submit a term to search. I catch the term with a POST handler method, and then do some calculation and hope to redirect the result to be used at another page (/WEB-INF/jsp), for example, we say build a graph based on the result. The problem is how to gather the results and redirect the URL at the same time. The Controllers like below:

Code:

---

@RequestMapping(value="/termForm", method = RequestMethod.GET)
public ModelAndView  setupForm() {
Term termClass = new Term();
return new ModelAndView("term", "command", termClass);
}
@RequestMapping(value="/getTerm", method=RequestMethod.POST)
public String getTerms(@ModelAttribute("term") Term term, BindingResult result)
{
    String label = term.getTerm();

    //doing some calculation to term here
    result = ....
    return "redirect:"+ "graphPage.jsp";
}

---

By searching, I found that Spring View Resolver only could process the redirected jsp under root directory (as same with index.jsp). In this case, the "result" seems not accepted by "graphPage". I also included UrlBasedViewResolver in XXX-servlet.xml as following:

Code:

---

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

Sorry for the long question, please give any hint to do this. Thanks a lot.
