Your bean definition of the Action is not correct. You have to define a controller bean with some valid name like:
<bean name="helloWorldController" class="com.raistudies.action.HelloWorldAction" />
Then you need to add the url mapping definition to your configuration to map requests to the defined controller.
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello.htm">helloWorldController</prop>

Change the <a href> to get the actual url like this
<a href="<c:url value="/emp"/>" />
Also make sure that the Dispatcher servlet is mapped in your web.xml

More about Spring MVC implementation can be found here
I've solved it by adding
<prop key="emp.htm">empController</prop>
and
<bean name="empController"
class="org.springframework.web.servlet.mvc.ParameterizableViewController"
p:viewName="emp" />
#Daniel
Yes, I can see that emp.jsp is a simple message jsp. The thing is this is how MVC pattern works(no thing to do with Spring). MVC is all about having a dispatcher sitting in front of all request and route the request to proper resources(e.g. controller,servlet, etc)
If the message in the jsp is dynamic generated, I reckon the request should go through a controller and forwarded to emp.jsp. If the whole point of emp.jsp is just some kinda of static page, you can put emp.js under webapp/static/emp.jsp and in your spring servlet configuration file indicate that everything under /static should by pass Spring ServletDispatcher.
The configuration file will look like this
<mvc:resources mapping="/static/**" location="/static/" />
By doing so, the request /static/emp.jsp will work and do not go through Spring DispatcherServlet.
I'm new to Spring framework. I just started implementing multiaction controller in netbeans. But. I'm getting the above error. I'm pasting my code below. Plz take a look into it and resolve me the issue.

Try checking your apachelog in the output Window of netbeans and see what's the default mapping of your controller in it, and append that mapping in the index.jsp.
For example in the log you'll find
Mapped URL path [/employee] onto handler '/*.html'
Simply append employee/add.htm in the JSP
Have you considered using #Controller annotated classes? Since spring 2.5 annotations are usually preferred.
Here's an example web.xml:

I'm trying to set up a skeleton Spring 3 MVC project but i'm having difficulties getting the views to render. I have followed the structure as described in the mvc-basic sample project and at http://blog.springsource.com/2009/12/21/mvc-simplifications-in-spring-3-0/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Interface21TeamBlog+%28SpringSource+Team+Blog%29 to set up the web.xml, app-config.xml and mvc-config.xml files. The controller gets called but when it reaches the point of finding the view and rendering it i get a 404 error. The files are as follows:

#Controller
#RequestMapping(value="/helloworld")
public class HelloWorldController {
#RequestMapping(method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("helloworld");
mav.addObject("message", "Hello World!");
return mav;
}
#RequestMapping(value="/Second", method = RequestMethod.GET)
public ModelAndView Second(){
ModelAndView mav = new ModelAndView();
mav.setViewName("Second");
mav.addObject("message", "Hello World!");
return mav;
}
}
and in WebContent/WEB-INF/views i have:
WebContent (folder)
WEB-INF (folder)
views (folder)
helloworld (folder)
helloworld.jsp (.jsp view)
helloworld.jsp (.jsp view)
welcome.jsp (.jsp view)
The views have straighforward html in them. When i request http://localhost:8080/projectname/app i correctly get the the views -> welcome.jsp page. However when i request http://localhost:8080/projectname/app/helloworld or http://localhost:8080/projectname/app/helloworld/ execution hits the correct controller actions but i get HTTP Status 404 - /projectname/WEB-INF/views/helloworld.jsp
Can anyone advise as to what is wrong?
Thanks
There are a few issues. The first one is that you only dispatch /app/* urls to Spring in your web.xml:
<url-pattern>/app/*</url-pattern>
That's fine if the request mapping was /app/helloworld, but means that /helloworld doesn't even get to spring. What you're probably wanting to do is to use a urlrewrite filter to map requests into the /app/* space.
Take a dependency on tuckey and then add this to your web.xml:
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Then add a file called urlrewrite.xml in your WEB-INF directory, containing:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd">
<urlrewrite default-match-type="wildcard">
<rule>
<from>/images/**</from>
<to>/images/$1</to>
</rule>
<rule>
<from>/scripts/**</from>
<to>/scripts/$1</to>
</rule>
<rule>
<from>/styles/**</from>
<to>/styles/$1</to>
</rule>
<rule>
<from>/**</from>
<to>/app/$1</to>
</rule>
<outbound-rule>
<from>/app/**</from>
<to>/$1</to>
</outbound-rule>
</urlrewrite>
After that, a request to /helloworld should go to the correct place. You'll probably want to change the root view controller too:
<mvc:view-controller path="/" view-name="welcome"/>
Looks like it is because you have not specified the viewClass property.
Can you try with
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
It works for welcome page due to this
<mvc:view-controller path="/app" view-name="welcome"/>
I think the view needs to be in views/helloworld.jsp and not in views/helloworld/helloworld.jsp
You should set view Name as
mav.setViewName("/helloWorld/helloWorld");
You should change "mvc-config" to yourname-servlet.xml" yourname should be match with your servlet name in ur web.xml file that in ur case should be myservlet-servlet.xml because the spring dispatcher servlet look for the file with "-servlet" extension file name in WEB-INF folder.
and in your myservlet-servlet.xml file for suffix part you should say in this way : "WEB-INF/yourfoldername(e.g. view)" till your controller look for ur view name that u mentioned in ur controller method (e.g ModelAndView("hello")).
As you have following configuration:
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
and your controller returning clean view name.
Verify your view files exists inside /WEB-INF/views/ while you run application.
