public class XMIMenuTreePortlet
XMIMenuTreePortlet is a convenience implementation of a portlet that exposes a static portlet menu based on the content of an XMI file.
The XMIMenuTreePortlet is a default implementation for the Portlet interface. If a portlet uses a static XMI tree, IBM recommends that it derives from XMIMenuTreePortlet. The tree structure is completely defined in an XML file, e.g., menu-tree.xml. In the deployment descriptor portlet.xml, the configuration parameter XMIFilePath for the concrete portlet specifies the full path of this XML file relative to the directory <Portlet_HOME>/war. The method getMenu(com.ibm.wps.portlet.menu.MenuContext) does not have to be implemented any more.
The following example shows a section of portlet.xml including the configuration parameter for XMIFilePath.
<concrete-portlet href="#Portlet_1">
<portlet-name> ... </portlet-name>
<config-param>
<param-name>XMIFilePath</param-name>
<param-value>menu-tree.xml</param-value>
</config-param>
</concrete-portlet>
The next example shows how menu-tree.xml can be implemented to create a menu tree with two nodes and two subnodes of the first node. Title and description are set in two different locales.
Code of menu-tree.xml:
<!DOCTYPE menu-tree PUBLIC "-//IBM//DTD Portlet Menu 1.0//EN" "menu-tree.dtd">
<!-- root node -->
<menu-tree id="id0">
<!-- root node -->
<menu-node id="rootId">
