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
h3One 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
titleTree/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

http://struts.apache.org/dtds/struts-2.0.dtd;
struts

action name=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
