portlet:renderURL to MVC Controller

[Coffeejoy]

I'm abit confuse how to direct an anchor tag to a Spring MVC controller
Do I handle the request in the handleRenderRequestInternal method? and how do I redirect to another different controller from a current controller?

Greatly appreciate for any inputs.

LoginController.java

public class LoginController extends SimpleFormController
{
	
	@Override
	protected ModelAndView handleRenderRequestInternal(RenderRequest request,
			RenderResponse response) throws Exception {
		if ("logout".equals(request.getParameter("action")))
		{
			// how to redirect to LogoutController from here
		}
		
		return super.handleRenderRequestInternal(request, response);
	}
}

login.jsp

<portlet:renderURL var="renderAction">
	<portlet:param name="action" value="logout" />
</portlet:renderURL>
<a href="${renderAction}"><spring:message code="logout.button"/></a>

login-portlet.xml

<!-- Parameter Handler Mappings -->
<bean id="logoutController" class="com.portlets.login.controller.LogoutController"/>
<bean id="loginController" class="com.portlets.login.controller.LoginController">
	<property name="commandName" value="webUser"/>
	<property name="commandClass" value="com.portlets.login.model.WebUser"/>
	<property name="formView" value="login.view"/>
	<property name="successView" value="login.view"/>
</bean>
<bean id="parameterHandlerMapping" class="org.springframework.web.portlet.handler.ParameterHandlerMapping">
	<property name="parameterMap">
		<map>
			<entry key="login" value-ref="loginController" />
			<entry key="logout" value-ref="logoutController" />
		</map>
	</property>
</bean>

The method you use to override to handle the request depends on the type of Spring controller you are using. The handleRenderRequestInternal method shouldn't generally be overriden (except AbstractController I think), there will usually be more specific method(s) that you override to hook into the particular controller's workflow. The javadoc for each controller shows the workflow and hooks for the controller.

There is a recent discussion on redirecting between portlet controllers in http://forum.springframework.org/showthread.php?t=58357. Note you can only redirect between controllers when moving between the action and render phases of the portlet processing. Redirects to EXTERNAL urls are also only possible from the action phase using the portlet api.

Hope this helps,
