Liferay Portlet development with Spring: No handler found for request error

[Christian Esocidae]

Hello,

first of all I am pretty new to portlet development and spring and I am kind a guessing that this is quite a simple problem. But I already spent two days trying to fix it and have still no clue. So I hope you can help me out.

Tools and technology in use:
Netbeans Portal Pack 3
Glassfish 2.1
Liferay Portal Standard Edition 5.2.3
Spring 2.5 Portlet MVC Framework

The Problem:
I am able to build the portlet and deploy it in liferay with the following message "Portlet is temporarily unavailable".

Here is the snippets of the Netbeans console output:

  [AutoDeploy] Successfully autodeployed : C:\Programme\glassfish\domains\domain1\autodeploy\MontyBrogan.war.
16:55:59,640 INFO  [PluginPackageUtil:1153] Reloading repositories
16:57:22,609 ERROR [DispatcherPortlet:501] Could not complete request

        at org.springframework.web.portlet.DispatcherPortlet.noHandlerFound(DispatcherPortlet.java:951)

       ...
  

In addition my config files:

Thanks in advance.

Hi Christian,

I hope you have found a solution to your problem by now. But I'll post my hypothesis.

I think your probleme is in your applicationContext.xml. You're missing your controller initialization.

Here's an example:

<context:annotation-config/>
  
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="cache" value="true"/>
	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	<property name="prefix" value="/jsp/CalendarEventManager/"/>
	<property name="suffix" value=".jsp"/>
</bean>
  
<bean class="org.springframework.web.portlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
<context:component-scan base-package="com.lacitecollegiale.controller" />

Also you could take a look at these examples :

http://books.dzone.com/articles/spring-30-portlet-mvc-part-2

Hope this helps,

Matthieu
