how to pass parameters from jsp to java class using RESTFUL - rest

Question

i hav created a jsp page from which i m taking some values and on submit it should pass the parameters to the java class using rest.
< form id="payment" method="post" action="addtogroup">
< ol style="padding: 0;">
< li>< label for="groupId">Group id:< /label>
< input type="text" id="groupId" name="groupId"/>
< br />
< li>< label for="vendorId">Profile Id :< /label>
< input type="text" id="vendorId" name="vendorId"/>
< li>
< input type="submit" value="Submit"/>
< br />
< /ol>
< /form>
and the java code is:
#RequestMapping(value = "/addtogroup/{groupId}/{vendorId}",method = RequestMethod.POST)
public String addtoGroup(#ModelAttribute("groupId") String groupId,#ModelAttribute("vendorId") String profileId){
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String username = auth.getName();
System.out.println("group id is="+groupId);
System.out.println("profileId is="+profileId);
System.out.println("username is="+username);
grpDao.addToGroup(groupId,profileId,username);
return "addtogroup";
}
when i type [http://localhost:8080/biznex/rest/addtogroup/2/13] in the address bar directly the code is executed.
but when i click submit button in the jsp i get page not found error.
plz help me out.

Answer 1

< form id="payment" method="post" action="addtogroup"> This statement means submit the FORM data using POST method to the url "currentpath"/"addtogroup"
However, your RESTFUL Server side component expects the url in the form of /addtogoup/{groupid}/{vendorid} in a GET method
I would suggest you to have a JavaScript method which converts your form fields to the URI path- using jQuery or plain JavaScript

Answer 2

As thewhiterabbit wrote, you have to pass the complete REST url with the groupid and vendorid.
In order to build it you don't need to use JS, it's enough the spring tag library. Here, how it works:
<spring:url value="/addtogoup/${form.groupid}/${form.vendorid}" var="actionURL"/>
<form:form method="POST" action="${actionURL}" modelAttribute="form">
