JSF Tree construction - My Faces Tree2 Component development

Question

Hi
I am planning to recommend JSF and MyFaces for the development of the application.
like Navigation Tree on the left side, header, footer and body ..
1) Can any one share a piece of code to develop Dynamic Navigation Tree(like ServerSideToggling ..I will get the data from backend based on the I will build the Tree with leafs, when we click on leafs we need to call action to redirect to other jsps ) we can achieve this using MyFaces Tree2 Component,Just wondering if anybody know some information, any info is appreciated.
Parent1
|
--Child1__
|--sub child 1
--Child2
--Child3
Parent2
|
--Child1__
|--sub child 1
--Child2
--Child3
Conditions:
1) Need to construct the Tree based on backend data.
2) All the Parents and Children should be links, like when I click on any link, I need to call an action and forward it some other page.
For testing I hardcoded and built one tree, which look similar...but the dynamic tree needs server side toggling..which requires...handling of backend data...constructing a tree...If you could share a sample, I will be appreciated...mean while I will try to do this...
thanks

HI jish,
A couple suggestions.
While the MyFaces (tomahawk) components may be very useful, I would encourage you to make sure you're using JSF from the Mojarra project. It is more stable and better supported: https://javaserverfaces.dev.java.net
Also, I would encourage you NOT to use JSPs. JSF 2.0 will favor a facelets-style syntax, so you should consider using Facelets or JSFTemplating instead. JSP is also slower and more cumbersome to work with. Try: https://jsftemplating.dev.java.net or https://facelets.dev.java.net . Either one of these projects replace JSP and provide "templating" support (which doesn't exist when using JSP) as well as many other features to help you (like JSFTemplating's factories for creating dynamic trees).
I don't use MyFaces Tree2 component (I use Woodstock's Tree component), however, I think the concepts should be the same. Here's some a link to a very complicated example (GlassFish Admin Console Tree code which is generated from several backend sources + updated via Ajax):
https://glassfish.dev.java.net/source/browse/glassfish/admin-gui/src/docroot/peTree.jsf?rev=1.12&view=markup
A more simple example:
<sun:tree text="Tree Example" clientSide="false" url="http://www.google.com">
    <sun:treeNode text="Static Tree Node" actionExpression="#{some.thing}">
        <dynamicTreeNode treeAdaptorClass="com.sun.enterprise.tools.admingui.tree.MBeanTreeAdaptor"
            objectName="com.sun.appserv:type=applications,category=config"
            methodName="getAllDeployedJ2EEApplications"
            text="Dynamic Tree Node"
            url="/applications/enterpriseApplications.jsf"
            attributeName="name"
            childURL="applications/enterpriseApplicationsEdit.jsf?appName=#{$this{valueBinding}.text}" />
    </sun:treeNode>
</sun:tree>Another place to look is the scales project. The lead developer on that project is actively developing a Tree component that will have a very clean interface to interacting with dynamic trees.
Good luck!
