How to do it in JSP

Hi all
Just calling only one method I get the data as follows.
E004010001E1B520 E004010001E1B520 E004010001E1B520 E004010001E1B643 E004010001E1B678 E004010001E1B678
What I wanna do it that this value(E004010001E1B520) appears three times, I wanna print it only once and count the number of appearance and same thing with other values(E004010001E1B643) and(E004010001E1B678).
I mean I wanna print in a table it as follows
Sl. No TAGID COUNT
1 E004010001E1B520 3
2 E004010001E1B643 1
3 E004010001E1B678 2
Thanx

well you have evrything with now, you did find how many occurances where there too.... in order to display the result using JSP use the following class as a bean & in order to find the total number all you can do is to sum everything up.
place SampleRfInputDemo.class at <Your_web_appln/web-inf/classes/com/RfDetect path and to the above code add an extra line right at the top pckage com.RfDetect;
i.e
package com.RfDetect;
import java.util.Collections;
import java.util.List;
import java.util.ArrayList;
import java.util.Map;
import java.util.TreeMap;
import java.util.StringTokenizer;
* Author : rahul.a
class SampleRfInputDemo{
//Sample input
static String in = "E004010001E1B520 E004010001E1B520 E004010001E1B520 E004010001E1B643 E004010001E1B678 E004010001E1B678 E004010001E1B521 E004010001E1B520 E004010001E1B678";
/* The following method resolves the input and converts it into a Sorted List */
public List<String> saveRfConsoleIp(String InputString) {
ArrayList<String> SampleList = new ArrayList<String>();
StringTokenizer st = new StringTokenizer (InputString," ");
while(st.hasMoreTokens()){
String value = st.nextToken();
SampleList.add(value.trim());
Collections.sort(SampleList);
return(SampleList);
/* Final Map Which arranges data in format
*E004010001E1B520 = <Number_of_occurances>
public Map<String,Integer> getRfIpMap(List<String> list){
TreeMap<String,Integer> map = new TreeMap<String,Integer>();
int count = 1;
if(list.size() > 0 && list != null){
map.put(list.get(0),count);
for(int i=0;i<list.size() - 1;i++){
   if(list.get(i).equals(list.get(i+1)) == true)
     count = count + 1;
   else
     count = 1;
   map.put(list.get(i+1),count);
return(map);
}and compile the file to genarate a new SampleRfInputDemo.class file there and then try the code mentioned below...
<%@page language="java" import="java.util.Map,java.util.Set"%>
<jsp:usebean id="sample" class="com.RfDetect.SampleRfInputDemo" />
<%
Map<String,Integer> OutPut = sample.getRfIpMap(sample.saveRfConsoleIp("E004010001E1B520 E004010001E1B520 E004010001E1B520 E004010001E1B643 E004010001E1B678 E004010001E1B678 E004010001E1B521 E004010001E1B520 E004010001E1B678"));
int SIZE = OutPut.size();
%>
<html>
<head>
<title>Rf Indication</title>
</head>
<body>
<table border="1">
<tr>
<th>SNO</th>
<th>RFID</th>
<th>COUNT</th>
</tr>
<%
int totcount = 0;
Set key = OutPut.keySet();
Object keys[] = key.toArray();
for(int i = 0; i < SIZE ; i++){
out.println("<tr><td>"+(i+1)+"</td>");
out.println("<td>"+keys[i]+"</td>");
out.println("<td>"+OutPut.get(keys)+"</td>");
out.println("</tr>");
Integer inc = (Integer) OutPut.get(keys[i]);
totcount = totcount + inc.intValue();
%>
</table>
<%
out.println("The total count is "+totcount);
%>
</body>
</html>
However,it would be lot better if we can use JSTL instead of scriptlets for better readablity.
Hope this helps

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.

We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript

Hi, I don't know if it may be the cuase of your problems, but you should narrow the Object obtained doing the lookup, like this:
FirstHome home = (FirstHome) PortableRemoteObject.narrow(ctx.lookup("FirstEJB"), FirstHome.class);

How to display PDF in JSP using Iframe

Hi All,
I am using Struts 2. I am building my file in ActionClass with seperate Method like getGeneratedPDF() in which, I am setting header of response and writing into PDF.
This method will be called from JSP by this way
s:property value="getGeneratedPDF()" />
But It displayed Junk Characters , and this PDF is not static (already Generated). It is generated and build on Fly.
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?
questions 2 -- How to display it in Iframe?
Please help me , If you know the solution.
Thanks in Advance,
Jimmy

It is generated and build on Fly.A PDF file is a binary file, not a text file, and you're trying to display it as String. Of course you would get "junk characters". Have you ever tried opening a binary file (pdf, doc, jpg, xls, etc) using a text editor like Notepad?
I have 2 questions 1 -- How to display PDF in JSP in proper way without Junk Character in it?Display it as binary stream, not as text stream. You can display it standalone, just let the link/form/addressbar URL point to some Servlet which writes the InputStream of the PDF file to the OutputStream of the response, along with a correct set of response headers (at least content-type, content-disposition and content-length), so that the browser can open it in the correct application (which is usually Acrobat Reader). If you want to embed the PDF file in a JSP, then one of the ways is indeed using the HTML <iframe> tag.
questions 2 -- How to display it in Iframe? Just let the iframe URL point to the aforementioned Servlet.
You can find here an example of a generic file servlet, you may find it useful to get the idea how to do it: [http://balusc.blogspot.com/2007/07/fileservlet.html].

How to do validation in jsp using javascript

how to do validation in jsp using javascript

The same way you do with any HTML page.
Catch the onclick/onsubmit event, do your validation in javascript and then allow/cancel the action as required.
However this is javascript validation only - javascript can never call JSP code.

Read a cookie in jsp
HttpSession session = request.getSession();
Cookie cookie_session = getCookie(request, "COOKIENAME");
          if (cookie_session == null) {
               sesID = session.getId();
          } else {
               sesID = cookie_session.getValue();
          }or
get all cookie in the browser
This gets all the cookies and according to the cookie name given u can get the cookie value
Cookie[] cookies = request.getCookies();
          if (cookies != null) {
               for (int i = 0; i < cookies.length; i++) {
                    if (cookies.getName().equals(cookieName))
                         return cookies[i];
               }but i am not sure if this works for ur requirement try and see

How to use threads in JSP???

hello
i want to use threads with JSP.
i want to write a jsp page which will
start 2 different threads. the 1st thread should just display a message and the second page should redirect this page to another jsp page.
till the redirection is goin on, the message should be displayed in the browser from the 1st thread.
i dont know actually how to use threads in JSP by implementing the Runnable insterface, if not m then how do i do it ??
thanx
Kamal Jai

Why do you want to use threads to do this ??
If you write a message and do a redirection, the message will be displayed until the other page will be loaded into the browser...
I already launched a thread from a JSP but it was for a four hour process where the user can close his browser windows.
