can any one help me out by sending any example code?
thanks in advance.

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>
                              </li>
                         </ul>
                    </li>
                    <li>
                         <input type="checkbox">Check 2</input>
                         <ul>
                              <li>
                                   <input type="checkbox">Check 2A</input>
                              </li>
                         </ul>

Hello Everyone,
I've a list that allows users to make multiple selections.
<select name=location multiple="multiple">

         All
    </option>
    <option>
         Hyd

</select>I want to get the selections made by user in jsp page from my servlet, selections can be multiple too.
ArrayList locList = new ArrayList();
locList = request.getParameter("location");when I do so, I get compilation error as the request returns string type. How do I then get multiple selections made by the user.
Please let me know.

For those kind of basic questions it would help a lot if you just gently consult the javadocs and tutorials.

How to get ep authority in jsp page

Hi all:
I want to create a j2ee project and some jsp pages to deploy to EP server.
My question is how to get user name or user authority in jsp page.
Is there any APIs to use or something else.
Thanks in advance.
Allen

Hai ,
I Think This will help ful for u check it ,
File=new FileLog("f:/WebServiceTrace/trace2.%g.log", 800000, 10,                                        new TraceFormatter());
The above code specifies the path for your log file.
Then add this file as a log location and then log the traces. For this you can use the following code like:
Location location=Location.getLocation(className);
          location.addLog(file);
          location.setEffectiveSeverity(Severity.ALL);
          location.entering(methodName);
To Create j2ee apllication
In path new-j2ee-jsp to create JSP's can only be used for J2EE applications.
So as you are using this in Portal Application, this does not work.
You can test this bahavior by creating a new Web Application (New-Project-J2EE-Web Module Project)
In this Web Module Project, try creating JSP, this will work.
So dont use new-j2ee-jsp to create JSP in Portal Application instead use New-File and name the file as jsp.

please help me if u can?

This should work but it needs testing out around midnight ( not sure if it is 00:00 or 24:00):
<%@ page import="java.util.*" %>
<html>
<head><title>Time Page</title>
</head>
<body>
<% Calendar c = Calendar.getInstance();
   c.add(Calendar.HOUR_OF_DAY, 4);
   int h = c.get(Calendar.HOUR_OF_DAY); %>
The current hour is <%= h %><br>
<% for (int i=0; i < 24; i++) { %>
   <input type=radio name=time <%= (i < h) ? "disabled" : ""%><%= (i == h) ? "checked" : ""%>><%= (i < 10) ? "0" : ""%><%= i %>:00<br>

How to get Parameters in a jsp page called by VB program via xmlHttp

I have a VB programm sending a request using xmlHttp.
xmlHttp.Open "POST", varTarget, True 'True means asynchronous
xmlHttp.Send xmlSendStr
This worked fine with ASP
the crucial ASP code was:
     set xml = server.createObject("MSXML2.DOMDocument")
     xml.load(request)
     VBData = cstr(xml.getElementsByTagName("value").item(0).firstChild.nodeValue)
now I have a webserver (tomcat) and try to have a simular functionality
but
request.getParameter()
seems not to do the job.
what do I have to do
I am thankfully looking forward to you reply
peter

Hi,
thanks for your reply!
If I have the parameters in the URL and use the method GET it works all right.
but I need the method to be POST. I suppose, I have the wrong way identifying the parameter name
This is from VB
varTarget = "http://localhost:9090/gm/getData" ' getData is my servlet
xmlSendStr = "SQLStmt=SELECT TCPD_Cars.* From TCPD_Cars WHERE (((TCPD_Cars.CarIdent)=45));"
    xmlHttp.Open "POST", varTarget, True   'True means asynchronous
    xmlHttp.Send xmlSendStrthis is part of my Servlet
     protected void doPost(HttpServletRequest request, HttpServletResponse response)
               throws ServletException, IOException {
          response.setContentType("text/html");
          PrintWriter writer = response.getWriter();
          String SQLStmt = request.getParameter("SQLStmt") ;
        //make the database query and get the returns
        writer.println(GetSQLData(SQLStmt));
        //close the write
        writer.close();
     }I would appreciate any suggestions

How to get the view tree from a jsp page

Hi,
I would like to get the view tree of a jsp page. The idea is to dynamically include the content of one or more jsf pages into a UIPanel during a "value changed" event.
So, i could get from an arbitrary page like ...
<%@ taglib uri="http://java.sun.com/jsf/core"   prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html"   prefix="h" %>
<h:panelGrid columns="3" width="100%" rowClasses="gridTop">
    <h:outputText value="#{someBean.someValue}"/>
</h:panelGrid>... the corresponding List of components...
Any idea?

Thanks for your answer Jayashri,
The view tree can be retrieved by this way during the page is parsed, for example with scriptlets <%%>, or once the page has been parsed (the view has been builded and attached to the FacesContext).
My problem is to get the view tree of a page from another Context.
The idea is to build a dynamic layout of some pages that represents "views". I can imagine this like the concept of perspectives and views of Eclipse IDE.
Because of the difficulty to build it with pure JSP (cannot use dynamic ID nor JSTL ForEach), I try to build it into my backing bean and to bind it with a <h:panelGrid/>. By this way, I'm not able to use the <jsp:include/> tag as I usually did to include some content into the view tree.
Sorry for my english ;)

Tree Structure in JSP

Hi,
I have an xml file , my requirement needs me to display the xml file as a tree structure in jsp. The user should be able to make changes to tree. he can drag and drop the nodes and save the changes.

Can anyone provide me with any useful tips or code. I can use javascript css java(not swing).Please reply ASAP as I have to complete it soon.
Thanks,

How to Hightlight the Data in Jsp Page

How to Hightlight the Data in Jsp Page,
I am doing doing search page,based on values given search page those are sent to servlet,in servlet based on some conditions if particuler id i am getting then i am redirecting to Respective jsp page with highlight the data from database..
Thanks in advance...

"Highlighting data in JSP sounds strange".
Without looking at your search specific algorithms I feel you are finally going to display a page (HTML content) to user which contains highlighted text. Highlighting is not directly related to server side language you use (JSP, ASP, PHP etc.). This is purely HTML and CSS. However, server side script (such as JSP) should generate HTML content for getting highlight effect.
Following HTML shows highlighted text using background-color property on span element.
<html>
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<body>
      <p style="font-size:1.1em">This is a long paragraph which contains <span style="background-color: yellow;">highlighted text</span> and non highlighted text.</p>
</body>
</html>Thanks,
