spring - jstl - Error 404 - The requested resource is not available

Question

When I want to access on my website, I've the following error :

The requested resource is not available.

I noticed that the problem is in the mvc-dispatcher-servlet.xml file on the line <mvc:resources mapping="/resources/**" location="../../resources/normalMode/"/> but I don't know why ?

Do you have any solutions ?

- src
  - main
    - java
      - com
        - myblog
          - controller
             -//all java files as controller
    - resources
       - normalMode
          - css
             - header.css

Answer 1

First of all you need to load the .xml files if you do not have them on class path

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   classpath:spring/application-config.xml,
   /WEB-INF/conf/mvc-config.xml 
  </param-value>
 </context-param>

now you need to do the following to enable the spring mvc using annotations

 <context:component-scan base-package="com.ekiras" />
 <mvc:annotation-driven />
 <tx:annotation-driven />

you need to enable the annotations and component scan to scan for all the annotations in the project.

See a demo project setup with SpringMVC + Maven + Hibernate + Sitemesh

Answer 2

You need to add

<mvc:annotation-driven/>

to your mvc-dispatcher-servlet.xml. With this configuration (and the component scan), Spring will scan and register your @Controller methods annotated with @RequestMapping.

With your current configuration, no such handlers were being registered and there was therefore nothing to handle your request to /.
