Spring MVC InternalResourceViewResolver and static resources - spring-mvc

Question

When I'm using InternalResourceViewResolver alone my views will be resolved correctly. When I add annotation-driven to my configuration file, my views are resolved but my resources are not. This is driving me crazy...
src
main
java
resources
css
js
ajaxHandler.js
webapp
WEB-INF
spring
appServlet
servlet-context.xml
views
index.jsp
internalview.jsp
web.xml
Here's my web.xml:
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>spring.introduction</display-name>
<servlet>
<servlet-name>ApplicationServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>ApplicationServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>WEB-INF/views/index.jsp</welcome-file>
</welcome-file-list>
</web-app>
The servlet-context.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.tsystems.sample" />
<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>
<mvc:resources location="/js/**" mapping="/resources/js/" />
<!--mvc:default-servlet-handler/-->
<mvc:annotation-driven/>
</beans:beans>
The basic flow:
Index.jsp has a form that passes "sender:index" as POST to the indexController. this should fall down to the following method:
#RequestMapping(value = "/Forward", method = RequestMethod.POST)
public ModelAndView forward(#RequestParam(value = "sender", required = true) String sender, Model model) {
m_logger.info(String.format("Captured sender attribute: " + sender));
ModelAndView mav = new ModelAndView("internalview");
mav.addObject("sender", sender);
return mav;
}
This works so far, the info message appears in the server log and the internalview show up. In my internalview.jsp I try to load the js as follows:
<script type="text/javascript" src="<c:url value="/js/ajaxHandler.js"/>"></script>
ending up with a nice 404 error and the message below in the server.log:
[org.springframework.web.servlet.PageNotFound] (default task-20) No mapping found for HTTP request with URI [/spring.introduction/js/ajaxHandler.js] in DispatcherServlet with name 'ApplicationServlet'
If I remove annotation-driven from the config file even my view becomes 404 NOT FOUND. If I remove annotation-driven AND mvc:resources it works but of course the .js is not loaded.
How can I resolve this issue? (There are similar questions as this but after trying out the answers for those, none of them worked so while I accept that the question may be duplicate to others, I'm still opening because none of their answers solves the problem)

Answer 1

Web resources such as JavaScript and CSS should typically be placed under src/main/webapp directory. So in your case (based on your mvc:resources mapping), you should create resources directory in src/main/webapp and move the js and css directories from src/main/resources there.
src/main/webapp/resources/js
src/main/webapp/resources/css
