Page redirect not working

[pramod talekar]

Hi,

In the below program, when I submit the login.jsp page, I get the "org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/Bookstore/index] in DispatcherServlet with name 'appServlet' message.The index.jsp page is in WEB-INF/views folder.

package com.apress.prospringmvc;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(value = "/login")
public class LoginController {

	public static final String ACCOUNT_ATTRIBUTE = "account";
	@Autowired
	private AccountService accountService;

	@RequestMapping(method = RequestMethod.GET)
	public String login() {
		return "index";
	}

	@RequestMapping(method = RequestMethod.POST)
	public String handleLogin(HttpServletRequest request, HttpSession session) {
		try {
			String username = request.getParameter("username");
			String password = request.getParameter("password");

			Account account = this.accountService.login(username, password);
			session.setAttribute(ACCOUNT_ATTRIBUTE, account);
			return "redirect:/index";
		} catch (Exception ae) {
			request.setAttribute("exception", ae);
			return "login";
		}
		// return "index";
	}
}

If I write return "index" instead of "redirect:/index" it works fine. Also If I move the index.jsp page out of the WEB-INF/views folder and keep it inside WebContent, it works fine when written as return "index.jsp". So how to redirect to a different page which is inside WEB-INF/views folder.

the WEB-INF/spring/appServlet/servlet-context.xml is as follows :

<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />

	<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
	<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/WEB-INF/views/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<beans:bean id="AccountService" class="com.apress.prospringmvc.AccountService"></beans:bean>
	
	<context:component-scan base-package="com.apress.prospringmvc" />
	

Please advise.

Also If I move the index.jsp page out of the WEB-INF/views folder and keep it inside WebContent, it works fine when written as return "index.jsp".

Here, it works fine when written as return "redirect:/index.jsp".

I found out the answer for this problem.
The dispatcher servlet couldn't locate any mapping for /Bookstore/index. So I modified the LoginController class

@Controller
public class LoginController {

	public static final String ACCOUNT_ATTRIBUTE = "account";
	@Autowired
	private AccountService accountService;

	@RequestMapping(value = "/index")
	public String login() {
		return "index";
	}

	@RequestMapping(value = "/login", method = RequestMethod.POST)
	public String handleLogin(@RequestParam String username,
			@RequestParam String password, HttpServletRequest request,
			HttpSession session) {

		try {
			/*
			 * String username = request.getParameter("username"); String
			 * password = request.getParameter("password");
			 */
			Account account = this.accountService.login(username, password);
			session.setAttribute(ACCOUNT_ATTRIBUTE, account);
			return "redirect:/index";
		} catch (Exception ae) {
			request.setAttribute("exception", ae);
			return "login";
		}
		// return "index";
	}
}

The only problem I see here is that the LoginController class has no more @RequestMapping available.
However, the tutorial I'm following has got the program running without this modification.
