How to Implement Dynamic Tree structure in jsp

Hi,
Does any body help me to solve out my requirement??
I want to display all my folder contents (parent & childs) in windows explorer format, the root folder path will come from database.
Thanks in advance

There are many ways to achieve this. The simplest would be to use some existing tag library that renders a tree structure and feed it with the required data.

How compile an entire tree structure packages in JDev

Hello there
When i use jdev i have the src folder (source files) and the classes folder (compiled files) as Jdev makes them, but the compiled files are not updated correctly.
For eg. i created a batch file that runs the application with this content
echo on
C:
set path=C:\Program Files\Java\jdk1.6.0_11\bin;%path%
set classpath=
cd C:\jdevstudio10133\jdev\mywork\Supreme\ProjectServer\classes
java project.main.Main
And the application started is an older version of the application that i have now, if i put the first line System.out.println("Message") even if i make and rebuild the project, the message will not appear and i dont know how to get the compiled files.
Also i tried to find out how to compile a tree structure of packages from command line but it seems very difficult. If anyone can give a reference.
Thank you.

User,
you left out vital information. Read this post before posting.
what happens if you delete the whole classes folder and rebuild the application? JDev will recreate the folder and you should see all changes then. If not you are not running the right classes.

Once you have the data in a list or something, can't you just use <c:forEach> and then output standard nested <ul> and <li> tags to give the tree structure.
<html>
     <style>
          li
               list-style-type:none;
     </style>
     <body>
          <form>
               <ul>
                    <li>
                         <input type="checkbox">Check 1</input>
                         <ul>
                              <li>

Dynamic menu in tree structure in JSP

Hi,
1) I need to display a dynamic menu in JSP. The menu depends on the values received from database. I need to show the items in the structure of tree (like parents, child relation). The tree can have multiple levels (the parent can have children & these children too can have children). This tree structure would be on left side of the screen.
I would like to use some custom tags rather than javascript. Can somebody post the custom tags or some samples?
2) Also, once the user selects different items from menu, different action classes should be called. And accordingly, the right side of the screen will show different data.
So, there should be any way to set different action classes for the menu items. Please post any samples or helpful links.

How to create dynamic tree based on BAPI

Hi
I am able to create dynamic tree based on flat file structure example given in SDN . But how to create the tree from BAPI directly.Also when I will be clicking on any leaf node of the tree some data related to the node will be passed to another view.
Regards
Ananda

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?

We have 3 regions over 50 plants and probably around 500 corporations.

How to create dynamic tree component

I am using netbeans 5.5 and visual web pack to develop my jsf application.
I want to add a tree component that will be tied to a table with following columns:
id,parent_id,name
Actually the table stores data in tree structure with parent_id storing the parent of the row.
So a row with parent_id = 0 will be the root nodes of the tree.
When ever any root node is selected i want to fetch its children from the database and populate then as children of that parent node.
The tree can go to any depth so i want to make my tree component dynamic enough to handle this requirement.
How can i accomplish this.
I just want to add listerner for the plus sign of every node so that when the plus sign of that node is clicked i just want to get the id of the corresponding node.

How to store a Tree Structure in Memory

hi all!
I wanted to show a Org Chart on web page. Recursion is used for constructing.Based on B/S architecture,(get Org from DataBase)this is not a effective way!! How can I store a tree structure(Org object are stored as TreeNodes) in memory for recursion??? Thanks!

My English is too poor! So I posted the interfaces blow.
I used these interface to construct a org tree(which will displyed in browser ),but it's
efficiency is low. (recursion)Because the org infor. are stored in database(thounds of
orgs are stored).(I think this is the bottleneck)
Now I want to store the tree structure in memeory! Then jsp page only needs to build the tree
from memory!Needn't make a DbConnection every time. A timer will updated tree org(in memory)
automatic
So I want to use a N dimensions array to store the data (N is the number of orgs)
but I don't konw how to make a compositor for sorting!
after sorting .look at the matrix I poster blow(eg.)
Matrix:(a,b,c,d are orgs 1 mean's is parents 0 means not, this is a Sparse Set huh? ^_^ )
* a b c d
a 0 0 0 0
b 1 0 0 0
c 1 0 0 0
d 0 1 0 0
Org tree:
a
b c
d
so O(n(n-1)/2)
question:
1)How to sort orgs?
2)Any good suggestion is wanted!
Thanks!
interfaces
public interface IOrg { //entity class
public String getName(); //get Org Name
public String getId(); //get Org Id
public String getLevel(); //get Org Level (as String)
public String getParentId(); //get parent org Id
