The problem is the result of encoded message can't not restore to the original message by the decoder. Here are my three class's code
SecureMsgMain:
package securemsg.core;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;
import securemsg.database.*;
public class SecureMsgMain {
[Code] .....
So it is the question: This program implements a simple "decoder ring". It will prompt the user for a message to decode and decode the message based on the following substitution rules:
ABCDEFGHIJKLMNOPQRSTUVWXYZ will map to
ZEBRASCDFGHIJKLMNOPQTUVWXY
abcdefghijklmnopqrstuvwxyz will also map to
ZEBRASCDFGHIJKLMNOPQTUVWXY
any other characters (like space, punctuation, will map to themselves)
so if it sees an 'A' (or an 'a'), it will map to 'Z', etc... All i could think of is this but can't figure out the rest.
import java.util.Scanner;
public class DecoderRing
{
public static void main(String[] args)
{
String1[] = 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z';
String2[] = 'Z','E','B','R','A','S','C','D','F','G','H','I','J','K','L','M','N','O','P','Q','T','U','V','W','X','Y';
}
}
Not sure, what things are necessary such as switch statements or if and else or for loops and such...

public class InstantMessageFrame extends JFrame
{
private JList friends;
private JTextField message;
private JButton send;
[code]...
1. Open the source code file of your InstantMessageFrame class from Lab 12.2.
2. Add the following three fields to the InstantMessageFrame class: a JTextField named message, a JList named friends, and a JButton named send.
3. Add a method to your InstantMessageFrame class named getMessagePanel()that returns a JPanel and has no parameters. (This method will create a JPanel that will appear in the south border of your JFrame. It will contain a text field in which a message can be entered and a button that sends an instant message to all the friends in the list.)
4. Within getMessagePanel(), instantiate a new JPanel and give it BorderLayout.Assign a message equal to a new JTextField by using the no-argument constructor of JTextField. Assign send to a new JButton,passing in "Send" to the constructor. (This will be the label on the button.)
5. Within getMessagePanel(), add the message text field to the center of the JPanel and add the send button to the east border of the JPanel. The panel is now ready, so return the JPanel reference.
6. Add a method to your InstantMessageFrame class named get-FriendsPane() that returns a JScrollPane and has no parameters.(This method will create a scrollable list that will contain the names of others that you can chat with.)
7. Within getFriendsPane(), assign friends to a new JList by using theno-argument constructor of JList.
8. Within getFriendsPane(), instantiate a new JScrollPane using the following statement: JScrollPane pane = new JScrollPane(friends);
9. The scroll pane is ready, so return the reference pane at the end of getFriendsPane().
10. Within the constructor of InstantMessageFrame, invoke getMessagePanel(),placing the returned panel in the south border of the content pane of InstantMessageFrame.An Introduction to GUI Programming 399
11. Within the constructor of InstantMessageFrame, invoke get-FriendsPane(), placing the returned scroll pane in the center of the content pane of InstantMessageFrame.
12. Save, compile, and run the InstantMessageFrame class.Your InstantMessageFrame now has three visible components: a JList,a JTextField, and a JButton.
I'm very new to java code I'm currently learning about loops I've tried to write this for a statement in the program I'm making but its not working. I keep getting this message

I'm using Jgrasp for a complier
if i send messages as in the code below, is there a way to read only one message, if the client doesn't know how long it is (or if he only knows the maximum length)?in the documentation it says, that the method read(byte[]) reads until no data ist available or end of file is decteted. What does the latter mean? Can i extend the array that i sent by a byte that signals the end? Here is my Code:
Server
public class Server implements Runnable{
ServerSocket server;
HashMap<Short,Socket> clients;
public Server(){
clients = new HashMap<>();
[code]....
Both are startet in seperate threads. At the moment the first output of the client is "12 bytes read", and then continously "-1 bytes read"(because the server closes).
I am new to the JMS technology. I have written one sample sender and receiver program to pass a string message to the JMS queue and retrieve it back. It is working fine as well. But now, I want to pass a xml file to the JMS queue. Then from there I need to read the XML file and convert it into a Java object Using Jaxb. I know how to convert an XML into java object using Jaxb. But i am unable to send the XML file as a jms message to the listener.

In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it
Java Code:
JOptionPane.showMessageDialog(null, "message", "title", 1); mh_sh_highlight_all('java');
But when put in a loop, it does two things:
1) It hangs the program
2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).
I have a servlet that adds entries to a table and when there is a duplicate it redirects to an error page and I'd like to make it display the duplicate entry id.The problem is when I try to get the parameter and show the error (the duplicate entry id) on my jsp error page it shows null instead of the appropriate number.this is my servlet:

As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.

I've just recently started playing around with network programming in Java, and I've come up with a simplistic server than can handle multiple clients and return the IP and port each one is connected to (or I'm under the impression that is so). What I've been requested to do as an exercise by one of the programming teachers at my high school (I'm not in a class, this is my own time) is send a message from one client to the other through the ServerSocket so that it may "watch" everything going on. I'm not sure how to go about this at all.
EDIT : now it never seems to go the the else or else if statements...
That is now the main problem. It never, ever, goes past the first if statement, no matter what it is.
EDIT : Okay, I haven't changed a line of code but suddenly not a single if statement is working. They just stopped. The client simply hangs and I can't type anything.
Server
public class Server implements Runnable {
Socket clientSocket;
Server(Socket clientSocket) {
this.clientSocket = clientSocket;
}
public static void main(String args[]) throws Exception {
ServerSocket ssock = new ServerSocket(3480);
System.out.println("Listening on port 3480");

I have a problem on how to make my client to send the object to a server.
So I have one interface called "RMIInterface" and client "RMIClient" and server "RMIServer":
RMIInterface
interface RMIInterface {
public String getMessage(String text) throws RemoteException;
}
RMIClient
public class RMIClient {
[code]....
With this program I can connect to a Server with a Client, and print in Client console a message.But, how can I send message from a client to a server, and print that message in server console output?
make the simpliest example with sending a message to a server, edit inteface header code to public interface RMIInterface extends Remote, I forgot to add.
I am wondering why , when I click on the "Add Student" button on the GUI,the message dialog is not popping up.

I am implementing a SSO using NTLM. The steps are:
Step1: Cliente ask for resource
Step2: Server ask for NTLM negotiation
Step 3: Client sends to the server NTLM type 1 message
Step4: Server sends back to the client NTLM type 2 message
Step5: Client sends type 3 message.
The problem I have is in Step 5, when the browser receives the type 2 message, it just stops displaying "IE cannot display the webpage" and sends nothing to the server.
I have checked that I am sending a correctly the type 2 message, using a sniffer I can see the NTLM type 2 message (challenge) and it is well formed (I have test also different flags configuration). I have test also with Firefox and the same behaviour. Server and client are in the same Domain.
I am creating a JSF 2.0 project, and I am facing a problem when using the rich:pickList (richfaces 4) component with a custom converter.

I have an assignment, similar to ones of seen in the past. The assignment is to take a users text input and to encrypt it using 3 different types of encryptions: Caesar, Transpose, and Reverser. The professor gave us the bulk of the code, and more specifically how to tokenize and shift the letters using Caeser shift. The problem im coming across is that it is not showing anything past the users input. After running it, it just stays there running without showing anything.
Cipher:
package cipher;
import java.util.Scanner;
import java.util.StringTokenizer;
import javax.swing.JOptionPane;
public abstract class Cipher {
public String message;
StringBuilder encrypted_message, decrypted_message;
[Code] ....
The constants have their own separate class, and they appear to work fine. I know that the Transpose and Reverser are incomplete, hence them commented out. But if i cant finish with Caeser first, it wont work at all.
