  • How to get Tree structure in JSP page?

    Hi,
    I would like get data from the database and display the data in tree structure with the check boxes at each nodes on a jsp page with out using any third party tools. how can i do that? Do i require any new tags to fulfill this requirement?
    can any one help me out by sending any example code?
    thanks in advance.
    Regards,
    Reddy

    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>
                                       <input type="checkbox">Check 1A</input>
                                  </li>
                                  <li>
                                       <input type="checkbox">Check 1B</input>

  • 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.

  • Creating a tree structure like Windows file explorer using Jdev

    Hi All,
    Is it possible to develop a tree structure like windows in JDEV and then same page I want to move to oracle apps.
    This tree I am creating for Showing Employee information. Like Parents & childs under it. i.e. Managers and employee reporting to managers.
    Please let me know if it is possible, if yes how , what is method of doing this.
    Thanks
    Ganesh Mane

    Yes. This possible with ADF Faces RC, which provides an af:tree component. Have a look at the Fusion Order Demo, which uses the tree to implement a similar usecase to the one you describe.

  • 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.

  • Using tag library to create a tree in jsp

    Hi,
    I want to create a tree in a JSP page whose node values are obtained from the database. The number of children of a particular node is known only during the construction of the tree.
    Root
    |---Node I
    |----Node I Level 1 Child 1
    |----Node I Level 1 Child 2
    |----Node I Level 1 Child 2 SubLevel Child 1
    |----Node I Level 1 Child 2 SubLevel Child 2
    |---Node I Level 1 Child 2 SubLevel Child 2 Subsub Level1
    |----Node I Level 1 Child 3
    |---Node I Level 1 Child 3 SubLevel Child 1
    |---Node II
    |---Node n
    These node values are obtained from the database. Any early help is appreciated. Helping in tree construction using JSP & Tag Libraries is requested (not swings). Also help me in deploying the same in Tomcat 4.0 server.
    Regards
    Vimal

    I am not very knowledgable in tag libraries. Bust using pure java, you can do something like this:
    Create Node and NodeRenderer java classes. These classes will have methods to access their siblings, parent and its properties and to render itself using HTML code. When you read the database to retreive the tree structure, you can build a hierarchy of nodes. Each Node can render itself and by doing an appropriate traversal, the tree can be rendered.

  • How to  create Tree Structure for given data?

    Hi,
    I have to create a tree structure of Folders and the contents in the Folder.
    I have a XML, it contains data for the tree structure to display. How can I create a tree structure which would look like below
    Parent
       Child
         Supporting Views
            Raw eInfotree Table Views
            Background Calculations
            QC Data Views
         Calculation Views
         Unit Operation Views
            Cell Culture Views
            Purification Views
            MFR Views
         Personal Views
    All the nodes should have folder Icon.
    Please find the XML as

    Vishal,
    If you structure your data with two columns, the first being the Node name and the second being the Parent node name (see your information below), the iBrowser applet will make a nice data driven tree with all of the SelectionEvent or navigational capabilities you want.

    <Rowset><Columns><Column Description="" MaxRange="1" MinRange="0" Name="NAME" SQLDataType="1" SourceColumn="NAME"/><Column Description="" MaxRange="1" MinRange="0" Name="PARENT" SQLDataType="1" SourceColumn="PARENT"/></Columns>
