Class WpsStrutsTilesPlugin

java.lang.Object
  org.apache.struts.tiles.TilesPlugin
      com.ibm.wps.portlets.struts.plugins.WpsStrutsTilesPlugin

All Implemented Interfaces:

org.apache.struts.action.PlugIn

public class WpsStrutsTilesPlugin

extends org.apache.struts.tiles.TilesPlugin

The WPS Tiles Plugin is used to initialize Tiles in WebSphere Portal on top of the Struts Portlet Framework. This plugin is to be used with Struts 1.1 in association with WpsStrutsTilesRequestProcessor. It should be declared in all "struts-config.xml" files.

This plugin ensures a common definition factory for all modules. The definition factory configuration is read first from "web.xml" (for backward compatibility), then it is overloaded by values found in plugin property values.

The plugin changes the Struts configuration by specifying the WpsStrutsTilesRequestProcessor as the request processor. If the user has specified another request processor, this plugin should subclass the WpsStrutsTilesRequestProcessor class.

In case of several modules, the definition factory configuration is read by the first Tiles plugin to be initialized. The order is determined by the order of modules declaration in web.xml. The first module is always the default if it exists. The plugin should be declared in each struts-config.xml file in order to properly intialize the request processor.

Since:

4.2
