Porting a struts-based web application module into eXo Portal

First of all, I should thanks Punit Pandey for providing a good comparison among java portals solutions. When I read his article, I could make my decision to choose a portal as a platform for developing tomorrow application! Thank Mr. Benjamin Mestrallet and his staff for providing this wonderful portal.

The following steps should be perform to port a struts-based web application module into eXo Portal:

1. ExoStrutsPortlet should be introduced as the portlet class:
   File: portlet.xml

<portlet-app  ... >

  <portlet>

    ...

    <portlet-class>exo.portal.portlet.struts.ExoStrutsPortlet</portlet-class>

  </portlet>

</portlet-app>



2. welcome file of the application should be introduced as default-page:
   File: portlet.xml

<portlet-app  ... >

  <portlet>

    ...

    <init-param>

      <name>default-page</name>

      <value>/login.jsp</value>

    </init-param>

  </portlet>

</portlet-app>




Of course you should add mandatory parts, such as supported modes



3. PortletApplicationListener and ServletWrapper should be introduced in the web application as follow:
   File: web.xml
   
   

   <web-app>
   
       <listener>
   
           <listener-class>exo.services.portletcontainer.impl.servlet.PortletApplicationListener</listener-class>
   
       </listener>
   
       <servlet>
   
           <servlet-name>PortletWrapper</servlet-name>
   
           <servlet-class>exo.services.portletcontainer.impl.servlet.ServletWrapper</servlet-class>
   
       </servlet>
   
       <servlet-mapping>
   
           <servlet-name>PortletWrapper</servlet-name>
   
           <url-pattern>/PortletWrapper</url-pattern>
   
       </servlet-mapping>
   
   </web-app>

4. ExoActionServlet and /struts-controller should be introduce as action servlet class and its related mapping, as follow:
   File: web.xml

<servlet>

    <servlet-name>action</servlet-name>

    <servlet-class>exo.portal.portlet.struts.ExoActionServlet</servlet-class>

	...

  </servlet>



  <servlet-mapping>

    <servlet-name>action</servlet-name>

    <url-pattern>/struts-controller</url-pattern>

  </servlet-mapping>



5. ExoRequestProcessor should be added as request processor of the application module as follow:
   File: struts-config.xml

<controller processorClass="exo.portal.portlet.struts.ExoRequestProcessor"

              debug="1" contentType="text/html">

    ...

  </controller>
