Spring 2.5 with Ajaxtags

[sahiem shaikh]

Hi,

I am getting nullpointerexception in action class while passing a parameter from <ajax:tab> tag.
Please find the below given code for reference:

JSP file which contains tabs.

  
<div id="tabPanelWrapper">
	<ajax:tabPanel id="tabPanel_myTab">
		<ajax:tab caption="Introduction"  baseUrl="${pageContext.request.contextPath}/intro.action?make=intro" defaultTab="true"/>
	</ajax:tabPanel>
</div>

Spring-config.xml

    
<bean name="/intro.action" class="com.tr.ltc.earl.web.IntroductionController"  scope="request" />

Action Class:

    
public class IntroductionController implements Controller {

	public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		ModelAndView modelAndView = null;
		System.out.println("request.getParameter(make)");
		System.out.println("request.getParameter(make)"+request.getParameter("make"));
		if(request.getParameter("make").equalsIgnoreCase("intro")) 
			modelAndView = new ModelAndView("introduction");
		else
			modelAndView = new ModelAndView("myConfiguration");
	
		
		return modelAndView;
	}

}

Technologies which I am using:
Spring 2.5.6
Ajax-tags 1.5

Q1. Can we use Ajax tags with Spring application.
Q2. How to integrate ajax tags with spring.

Please help me to solve this problem. Your help will be highly appreciated.

Thanks in advanced.
