ModelAndView not returning model to the JSP in spring mvc
Question
I am trying to display the object in a jsp page that are returned via a controller, but I am not seeing the object in the jsp. Below is my controller:
@RequestMapping(value = "/search/{groupName}", menthod = {RequestMethod.Get, RequestMethod.POST})
public ModelAndView groupAlphaHandler(@PathVariable("groupName") String groupName, HttpServletRequest request) {
ArryList<GroupAlphaInfoVO> groupAlphaInfoVO = groupAlphaService.loadGroupAlphaSearchResult(groupName);
//view name "group-alpha"
ModelAndView mav = new ModelAndView("group-alpha");
mav.addObject("groupAlphaInfoVO", groupAlphaInfoVO);
mav.addObject("pageTitle", "Group Alpha");
//added debug point here and made sure groupAlphaInfoVO is not null (it has around 1000 records)
return mav;
}
Here is my jsp page group-alpha.jsp :
<html> <head> <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Group Alpha</title> </head> <body> ${pageTitle}<!-- this is getting displayed on jsp--> ${groupAlphaInfoVO} </body> </html>

Seems you are making a silly mistake in the controller
@RequestMapping(value = "/search/{groupName}", menthod = {RequestMethod.Get, RequestMethod.POST})
There is a spelling mistake. It's not **menthod** it's **method** And I think there is no need for using RequestMethod.POST
Another mistake is mav.addObject("groupAlphaInfoVO", groupAlphaInfoVO); with this code you are putting list of object. And in the JSP page you didn't do any operation on the list. To print that list you should write <c:forEach>....</c:forEach> code. For example
<c:forEach var="results" items="${groupAlphaInfoVO}">
<c:out value="${results.userid}"></c:out>
<c:out value="${results.password}"></c:out>
<c:out value="${results.role}"></c:out>
<c:out value="${results.contact}"></c:out>
<c:out value="${results.mentor}"></c:out>
<c:out value="${results.group}"></c:out>
</c:forEach>
For using you need to add JSTL dependency in your pom.xml
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
And add <%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %> at the top of your jsp page.

You need this isELIgnored="false"
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" isELIgnored="false"%> //here
