using simple url handler mapping

[pradeep talekar]

Hello,
I want to use simple url handler mapping for the following example :

index.jsp contains :-

<form name="loginForm" action="/upload.form" method="post">

web.xml [deployment descriptor] contains :-

 <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    
  </welcome-file-list>
  
  <servlet>
  	<servlet-name>rmc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet
</servlet-class>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>rmc</servlet-name>
  	<url-pattern>/*</url-pattern>
  </servlet-mapping>

rmc-servlet.xml contains :

<bean id="simpleUrlMapping" 
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
	<property name="mappings">
		<props>
			<prop key="/upload.form">LoginController</prop>
		</props>
	</property>
</bean>

<bean id="viewResolver"
    	class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
        <property name="prefix">
            <value>/WEB-INF/pages/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

<bean id="LoginController" class="com.sahyadri.controller.LoginController">
</bean>

LoginController.class contains :-

public class LoginController extends AbstractController{

	@Override
	protected ModelAndView handleRequestInternal(
HttpServletRequest arg0,HttpServletResponse arg1) 
throws Exception {
		ModelAndView model = new ModelAndView("HelloWorldPage");
		model.addObject("msg","hello World");
		return model;
	}
}

HelloWorldPage.jsp contains : -${msg}


But every time I get /upload.form resource not available.
I suspect there is some problem with the mapping.

Thanks a lot.

Is there a specific reason why you are not using the preferred @Controller model with the RequestMappingHandlerAdapter? This adapter is much more powerful and flexible than the others. Typically you should not need to implement any Spring interfaces or extend any Spring classes (like AbstractController) with the newer model. This decreases coupling to the framework.

See a sample application here:

The simple URL mapping requires explicit configuration for each controller and does not auto detect mappings. Using this approach will lead to very large config files if you have a large number of controllers.
