I am trying to build a Spring based web application and I would like to start with configuring a simple authentication system based on username & password tuples stored in a database table.
It is my understanding that this can be easily achieved using Spring security, but I cannot get it to work.
The following is my web.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<web-app
version="2.5"

</servlet>
<servlet-mapping>

</servlet-mapping>
Follows the servlet-context.xml file. The bob and sam users are there for testing purposes. After I get this right I will switch to a JDBC based user service.

This is my Home controller.
#Controller
public class HomeController
{
#RequestMapping(value = "/home.html")
public String home() {
return "home";
}
#RequestMapping(value = "/login-error.html")
public String loginError(Model model) {
model.addAttribute("loginError", true);
return "home";
}
}
And this is my thymeleaf based view.

When I deploy the WAR file to my local Tomcat installation and visit the http://localhost:8080/test/home.html URL, the home page opens fine. When I fill in the form, though, which gets submitted to http://localhost:8080/test/j_spring_security_check, I get a 404 - The requested resource () is not available. error.
What am I doing wrong? Please bear with me as I'm a newcomer to both Spring MVC/Security and Thymeleaf.
You need to configure Spring Security filter in web.xml
You cannot configure Spring Security in servlet-context.xml, because servlet-context.xml belongs to specific DispatcherServlet, but Spring Security filter works before request reaches any servlet.
You need to create a root application context using ContextLoaderListener and put Spring Security configuration there.
Actually, as long as you don't need separate servlet-context.xml and applicationContext.xml, I'd suggest you to move everything from servlet-context.xml to applicationContext.xml and leave servlet-context.xml effectively empty (that is, leave its <beans> element empty).

1.The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." I am completely new to SpringMVC and not able to solve this 404 please help me so that i can move forward to learn the subject . I tried everything that i got on internet

I am learning Spring MVC and I build the first "hello world" example. But I can not reach the page. It says "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." I am using Tocat 9.0 (I also tried Tomcat 8 still not working). So here is my code below
Controller:
package com.emin.springdemo.mvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/")
public String showPage() {
return "main-menu";
}

I know there is a duplicate subjects in the site. I tried them also didn't reach the solution.
The problem might be the dash since it's not a valid a Java identifier Try renaming jsp and return fileName.
The page you're requesting from browser is not found, so you need to add URL in below pattern:
localhost:(Port number) /project name/(request mapping at controller) /(request mapping at method)
Try mapping URL and restart server.
I have a jsp page called menu.jsp and I have given link to another page called ClsEdit.jsp by <a href="jsp/cls/ClsEdit.jsp?action=create">
When I give this line in menu.jsp, it loads without any problem. But when I give the same line in ClsEdit.jsp, I get the following exception. Please tell me what is the problem with the usage of links.

I'm developing in eclipse, and using Tomcat. the server log has no errors. Just the standard start-up log.
Please help me to point out where I am going wrong.
You haven't specified which URL you are hitting and what errors or output you are seeing so I will go by the files you have posted. There seem to be at least a few problems with what you have posted. I am assuming you are trying to access either http://[server]:[port]/index.jsp or http://[server]:[port]/.
Problem 1: When using an MVC framework you usually do not request web templates such as JSP files directly. Therefore, your welcome file list in web.xml should not contain index.jsp. It is more common to omit this section altogether. Instead, you should add a request mapping to the controller class for the application root, such as:
#RequestMapping("/")
public String home() { return "index"; }
Once you do this, you should be able to hit http://[server]:[port]/ and get a response.
Problem 2: The file index.jsp redirects to the URL proceed.do but there is no mapping for this URL in your controller. Instead, the controller has a mapping for the URL proceed. May be there was some confusion with Struts when you were trying to configure the URL mappings.
Problem 3: The file login.jsp submits to login.do but there is no mapping for this URL. Instead there is a mapping for login. The form action should therefore be changed from login.do to login.
Problem 4: The form in login.jsp is bound to a model attribute called Login but the controller does not add any model object with that name.
Problem 5: The form in login.jsp is submitted using an HTTP POST but the controller does not specify this for the login method. The default for controller methods annotated with #RequestMapping is HTTP GET so the login method will not be called when you submit the form.
Problem 6: The file index.jsp seems to be redundant as its sole purpose is to redirect to a different URL on the same server. You will be better off with the following simplified controller code:
#Controller
public class CommonController {
#RequestMapping("/")
public String loadLoginPage(Model model) {
model.addAttribute("Login", new Login()); // Or something like this, which represents the actual model object that should collect the login information.
return "login";
}
#RequestMapping(method = RequestMethod.POST, value="/login")
public String login(Login login) {
// Use the login object to authenticate the user.
return "abc";
}
}
I would also recommend that you keep the lines
<context:component-scan base-package="com.booksworld.controllers" />
<context:annotation-config />
<mvc:annotation-driven />
in the file dispatcher-servlet.xml as these lines are specific to your presentation layer.
