Doubt in javacard simple programming

We read that jcwde acts as a simulator to run the program(ie when only we don't have card terminal),
but we are owning a card terminal(gemplus) and card.
Then what's the use of jcwde tool (simulator) in running the application.
whether our card external program communicates with card resident program thru jcwde tools?
Is it takes(jcwde) any active role in storing the applet permanently in the card.
pls clarify our doubts at the earliest
thangs in advance
vinoth and vasan

The use of the JCWDE is to allow simulation of a card without a reader. Also the JCWDE allows you to set debugging features in your code that can't exist in a real applet. Even if you have a card and reader you'd still want to test your code in a simulator. You don't use the JCWDE to communicate with a real card. It doesn't store applets on card either. The role of the JCWDE is a first stage of testing. After that, you'll want to use the C-REF, which is a true JCVM. ( JCWDE runs Java VM ).
By the way, owning a card terminal isn't all that's needed to store applets on a card. You'll need a loader and that is provided by purchasing a kit.

Any ideas for a (fairly) simple program?

Does anybody have any ideas for a fairly simple program that I could try to write (I am a fair programmer, but I'm not to creative)?

You know, Java Game Programming for Dummies is actually a pretty good book (despite the "Dummies" part!) It is written in 1.0, but it has a "ponglet", card games, and several maze games. All the applets I've tried from them actually work (some typos in the book itself, but the CD is ok). Any of these could be "starter" code.
Yahoo has a whole bunch of Java applet games. You could try to reproduce pieces of the games you see. (These are also interesting in the sense that you can immediately see what works in a game and what doesn't.)
It is always fun to write little components. Cool buttons (write a nice little non-rectangular button that lights up or something), text boxes that look like digital displays, funny text labels (maybe with a weird font or with letters that jump all over the place when you mouse over them).. These don't take a whole lot of time to write, but write them well and they are very useful for your future games.
Enjoy!

Please help me with simple program

Can someone please write a simple program for me that opens up a webpage in the center of the screen , with a set size, and then asks the user where they would like to click on the screen. Then once the person clicks it asks how many times they would like to click there, and then once they enter the # the program opens up the webpage (in the center at the same spot as before, with the same set size) and automatically clicks on the predesignated spot , and then closes all open internet windows, and keeps doing it for however many times the person chose. PLEASE HELP ME WITH THIS!!! If you could, please post the source code here. Thank you so much to whoever helps me!!!!!!!

If it's not to learn, then what is the purpose of
this project?well, if it's not HW and its not for learning java, then why the hell would anyone like to have a program that may open a webpage and then repeatedly click on predefined place...
let me see...
now if he had asked for program that fakes IP as well, then i would suggest that he tryes to generate unique clicks, but now... i'm not sure... maybe just voting in some polls or smthing... though, i would not create a program that clicks on the link or form element, but rather just reload url with given parameters for N times...

JMS: simple program (urgent please)

I am quite new with the JMS. I am trying to have a simple program running in order to start from it towards the application I want to build.
I tried to run the sample program below:
package chat;
import javax.jms.*;
import javax.naming.*;
import java.io.*;
import java.io.InputStreamReader;
import java.util.Properties;
public class Chat implements javax.jms.MessageListener {
private TopicSession pubSession;
private TopicSession subSession;
private TopicPublisher publisher;
private TopicConnection connection;
/* Constructor. Establish JMS publisher and subscriber */
public Chat() throws Exception {
// Obtain a JNDI connection
Properties env = new Properties();
// ... specify the JNDI properties specific to the vendor
InitialContext jndi = new InitialContext(env);
// Look up a JMS connection factory
TopicConnectionFactory conFactory =
(TopicConnectionFactory) jndi.lookup("TopicConnectionFactory");
// Create a JMS connection
TopicConnection connection =
conFactory.createTopicConnection();
// Create two JMS session objects
TopicSession pubSession =
connection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
TopicSession subSession =
connection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
// Look up a JMS topic
Topic chatTopic = (Topic) jndi.lookup("anytopic");
// Create a JMS publisher and subscriber
TopicPublisher publisher =
pubSession.createPublisher(chatTopic);
TopicSubscriber subscriber =
subSession.createSubscriber(chatTopic);
// Set a JMS message listener
subscriber.setMessageListener(this);
// Intialize the Chat application
set(connection, pubSession, subSession, publisher);
// Start the JMS connection; allows messages to be delivered
connection.start();
/* Initialize the instance variables */
public void set(TopicConnection con, TopicSession pubSess,
TopicSession subSess, TopicPublisher pub) {
this.connection = con;
this.pubSession = pubSess;
this.subSession = subSess;
this.publisher = pub;
/* Receive message from topic subscriber */
public void onMessage(Message message) {
try {
TextMessage textMessage = (TextMessage) message;
String text = textMessage.getText();
System.out.println(text);
} catch (JMSException jmse) {
jmse.printStackTrace();
/* Create and send message using topic publisher */
protected void writeMessage(String text) throws JMSException {
TextMessage message = pubSession.createTextMessage();
publisher.publish(message);
/* Close the JMS connection */
public void close() throws JMSException {
connection.close();
/* Run the Chat client */
public static void main(String[] args) {
try {
Chat chat = new Chat();
// Read from command line
BufferedReader commandLine = new
java.io.BufferedReader(new
InputStreamReader(System.in));
// Loop until the word "exit" is typed
while (true) {
String s = commandLine.readLine();
if (s.equalsIgnoreCase("exit")) {
chat.close(); // close down connection
System.exit(0); // exit program
} else {
chat.writeMessage(s);
} catch (Exception e) {
e.printStackTrace();
But at the line
�TopicConnectionFactory conFactory =
(TopicConnectionFactory) jndi.lookup("TopicConnectionFactory");�
I got this exception:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

 at chat.Chat.<init>(Chat.java:24)
 at chat.Chat.main(Chat.java:94)
I realize that the problem is in the jndi setup. But, the problem is that I do not know where to go now and what should I do. I do not know how can I get the jndi.properties file and where and how to put it.
Please, kindly advise from your experience. I would appreciate clear steps to have this program running properly. Otherwise, if you do have a sample program that is already running, please provide it to me.

Thank you for your prompt reply.
I tried another example.

It is mentioned in SUN JMS tutorial that "When you use the J2EE SDK 1.3.1, your JMS provider is the SDK. " So I am using that and I did the follwoing:
--start the J2EE server as follows:
j2ee -verbose
Then I created the adminstrated object:
j2eeadmin -addJmsDestination MyTopic topic
But still getting this error:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
So now where is the error?
Thank you in advance

Even a simple program is not working ?

Hi there,
I typed a simple program to display the customer details. The program goes like this :
import java.lang.*;
public class Customer
     String custname;
     String custID;
public Customer()
     custname = "Bob";
     custID = "S20010";
public void displaydetails()
     System.out.println("Customer name is " + custname);
     System.out.println("Customer ID is " + custID);
public static void main(String a[])
     Customer cust = new Customer();
     cust.displaydetails();
The compilation went right. But, when I executed the program the following error message is displayed :
c:\>java Customer.java
Exception in thread "main" java.lang.NoClassDefFoundError: Customer/java.
Please help !!

Write a program that inputs a Java source code file and outputs a copy of that file with Java keywords surrounded with HTML tags for bold type. For example this input:
public class JavaSource
public static void main ( String[] args )
if ( args.length == 3 )
new BigObject();
else
System.out.println("Too few arguments.");
will be transformed into:

System.out.println("Too few arguments.");
In a browser the code will look like this:
public class JavaSource
public static void main ( String[] args )
if ( args.length == 3 )
new BigObject();
else
System.out.println("Too few arguments.");

Here is something that may get you started...
import java.io.*;
import java.util.*;
public class HtmlJava{
 public static void main(String arg[]){
 if(arg.length!=1){
 System.out.println("Usage java HtmlJava sourceFile");
 else
 new HtmlJava(arg[0]);
 HtmlJava(String source){
 try{
 BufferedReader sourceReader=new BufferedReader(new InputStreamReader(new FileInputStream(source)));
 BufferedWriter writer=new BufferedWriter(new OutputStreamWriter(new FileOutputStream(source+"Html.txt")));
 Vector keywords=new Vector();
 addKeywords(keywords);
 String line;
 StringTokenizer tokenizer=null;
 String word;
 while((line=sourceReader.readLine () )!=null){
 tokenizer=new StringTokenizer(line);
 while(tokenizer.hasMoreTokens()){
 word=tokenizer.nextToken();
 if(keywords.contains(word)){
 writer.write(""+word+" ");
 else{
 writer.write(word+" ");
 writer.write("\r\n");
 writer.close();
 sourceReader.close();
 System.out.println("Output File written to "+source+"Html.txt");

How to create a simple program

I downloaded JBuilder Foundation and it looks very complicated. I thought I could start a new project like you can in C++ Builder and choose "console application" and it would bring you to the code window with nothing in it or perhaps just a header file or two. But when I create a new project it brings me to a code window with a whole bunch of complicated code already there. And I don't understand any of it. Really what I want to be able to do is start a new project and just type this into the code window:
public class Welcome1 {
public static void main(String args[ ])
System.out.println("Welcome to Java!");
And then click Run and it outputs:
Welcome to Java!
But I don't know how to do that in this JBuilder. I may need to switch to another IDE or maybe just download a text editor and the Java SDK. If you can tell me what I should do that would be good. Thanks

download a text editor and the Java SDK.I'd recommend that. It's easy to learn an IDE afterwards, but many people are incapable of writing and compiling code without an IDE because they don't know how javac works etc.
For simple programs a text editor is more than enough, then once you get your head around the classpath, you're home free!

Any simple program available for testing instant client for Windows

Any simple program available for testing installation of instant client for Windows.
Thankx in advance

Having a program means you need a dev environment to compile, link and then test it with your instant client env.
I would suggest you download sqlplus ZIP and connect to a DB server.

I need a simple program to convert flac files to mp3 with album art

Is there a fairly simple program that will convert files and imbed album art by track? All of my music files are flac with album art included in the album folder.

Not sure of any software that will do the conversion and automatically embed album art, but LameDropXPD is a free, super-simple drag and drop conversion tool that will accept flac input: http://www.rarewares.org/mp3-lamedrop.php#lamedrop-current and MP3Tag (also free) has an option to do batch embedding of album art.

How can i make simple program to match colors ?(photos taken by camera)

how can i make simple program to match colors ?(photos taken by camera)

Hi khaledyr,
use a "random number" and compare for ">0.5" to get a (1 or 0) signal
What exactly are you searching for?
- Hints for choosing hardware?
- How to output voltage or relais signals?
- Help on using DAQ(mx)?
- Help on generating (boolean) waveforms?

Does anyone have a simple program that will return the size of a file

Does anyone have a simple program that will return the size of a file?

I quite hate it when I receive the incorrect amount of yoctocandela per metre squared. Swarthy people
can't properly convert poundal feet to barleycorn; throws off the whole conversion! Aaah, you get what
you paid for.I recognize those figures; you've got your outsourced file sizes from Zanzibar; admit it! I always apply
the scientific approach when I've got file sizes back from Zanzibar: I simply divide those numbers by
pi (very scientific) and drop the eleven (ueber scientific, because 11 is prime even when looked upon
as a binary number) least significant bits. And remember: never compare two floating point numbers
for equality. (<--- that's a free tip)
