Hi All,
Write some html page to call action for tree - home.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<META HTTP-EQUIV="Refresh" CONTENT="0;URL=treesupport.action">
</head>
<body>
<h3>One moment please.</h3>
</body>
</html>
Include Struts and Extended dojo tag libraries in your web-inf/lib folder
Below is the JSP page that will execute upon success of
treesupport.action, Named that as tree2.jsp
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<title>Tree</title>
<sx:head parseContent="false"/>
<script type="text/javascript" src="../dojo/dojo/dojo.js"
djConfig="isDebug: false, parseOnLoad: true"></script>
<script type="text/javascript">
dojo.event.topic.subscribe("nodeSelected", function(source) {
var selectedNode = source.node;
alert("You selected node " + selectedNode.title);
});
</script>
</head>
<body>
<sx:tree rootNode="rootNode"
childCollectionProperty="children"
nodeTitleProperty="title"
nodeIdProperty="id"
selectedNotifyTopics="nodeSelected" >
</sx:tree>
</body>
</html>
In Struts.xm, call the treesupport action on success return tree2.jsp
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd";>
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false"
/>
<constant name="struts.devMode" value="false" />
<package name="default" namespace="/" extends="struts-default">
<action name="treesupport"
class="org.kp.sample.TreeSupport">
<result>/paytools2/tree2.jsp</result>
</action>
</package>
<!-- Add packages here -->
</struts>
Write a Class with TreeSupport.java and Node.java - In Node.java. include
your business logic what values you want to populate in the tree. To make
this work, you have to create a project as Web2.0 and add struts2 and
dojo-tags to the library as well as dojo tool kit.
Hope this solves in creating a dynamic tree.
Thanks & Regards
