Faire un simple Treeview. Please!
Salut à tous, je souhaiterai faire un treeview simple pour comprendre comment marche struts layout pour faire des arbres, et je m'arrache les cheveux.
Voici ma page jsp treeview.jsp:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-layout.tld" prefix="layout" %>
<layout:html locale="true">
<head>
<title></title>
<link href="style.css" rel="stylesheet" type="text/css">
<html:base/>
</head>
<body>
<layout:treeview>
<layout:menuItem key="treeview.menu1" link="link1.html"/>
<layout:menuItem key="treeview.menu2">
<layout:menuItem key="treeview.menu2.submenu1">
<layout:menuItem key="treeview.menu2.submenu1.item1" link="link2.html"/>
<layout:menuItem key="treeview.menu2.submenu1.item2" link="link3.html"/>
</layout:menuItem>
<layout:menuItem key="treeview.menu2.submenu2" link="link3.html"/>
<layout:menuItem key="treeview.menu2.submenu3" link="link4.html"/>
</layout:menuItem>
</layout:treeview>
<layout:treeview name="java"/>
</body>
</layout:html> |
Voici ce que j'ai rajouté dans le struts-config.xml:
Code:

|
<action path="/treeview" type="...util.layout.MenuTreeviewAction">
<forward name="success" path="/treeview.jsp"/>
</action>
</action-mappings>
<message-resources parameter="ApplicationResources"/> |
Et voici mon action
