How can I connect to an SSH server in Java? I don't need/want a shell. I just want to connect to the SSH server and get the content of, say, file.txt. How can I do that? Example : I get host, user,pass in txt and connect it with java code!

Working on a project and am in need of some quick guidance to wrap things up. I have a functioning compression server that will create two files after the user gives it some input and a "magic string" to know when to stop reading input for that specific file.
I now need to connect a UDP web server to that compression server. the web server will read from the HTTP POST Request the data that was uploaded and send it to the compression server to create the two files... i have included both programs below
Web Server:
import java.io.*;
import java.net.*;
import java.util.*;
final class HttpRequest implements Runnable {
//Declare Constants and Variables
final static int BUF_SIZE = 1024000;
final static String CRLF = "
";
[Code]...
Compression Server:
import java.net.*; // for DatagramSocket, DatagramPacket, and InetAddress
import java.io.*; // for IOException
import java.util.zip.*;// for Zip
public class CompressionServer {
private static final int ECHOMAX = 65535; // Maximum size of echo datagram
private static final int BUFFER = 2048; // Buffer size for writing to Zip File

I'm working on an application I made a few years ago. At that time I connected to a local database so my address was 'jdbc:mysql://localhost:3306/'. That database is long gone so I recreated it on one of my hosted servers but I'm a little unsure of how to connect to it. At the moment I'm trying "jdbc:mysql://www.mydomain.com:3306/" but it is giving me an access denied error.
java.sql.SQLException: Access denied for user 'myusername'@'c-[my-ip].hsd1.pa.comcast.net' (using password: YES)Every result on Google seems to use localhost so I'm having a little difficulty figuring out the correct format.

I am developing a web application using JSF-2.0 on weblogic 10.3.6. I am using Facelets as VDL. I have 5 different machine. They are different according to their OS and their geographical location. On my first xhtml page server (machine) is decided. Then on next page file upload and rest of processing takes place. My restriction is that SSO configuration can be done on only one machine.
So I am restricted to using xhtml files from only my primary server where SSO configuration is done. But I have to connect to servlets or managed-bean of different machine as requests are machine specific and file needs to be uploaded to those machines for processing. So I cannot use redirectUrl as I need to be only on one machine. Is it possible that xhtml on one server can talk to managed-bean on other server(different machine)?.
I am working on a chess game. I need to construct a game room where all the player are present and room chat is up. Also some tables where games are being played. Now my question is how to create this game room?
To me this room must need to be like static or global (if I am not mistaken) that is up when server starts and players can join this room and should be down when server is done. How can I implement such room that would stay up for infinite time.
The goal is as follows: Write a UDP 'CompressionServer' that will take input from the user until it sees a "magic string" at which time it will create a compressed and uncompressed version of the file in the file system.
So, I need to integrate the following "Zip" code in to my UDP server code (which already creates the uncompressed file)... That is where I am stuck at now. My first few attempts had the Zip code after I write to "fout" but that failed to create a ZIP file.
I guess the main point here is what are the key pieces of the ZIP code that I should include and what would be the best spot to place them in my server code...
Zip Code:
import java.io.*;
import java.util.zip.*;
public class Zip {
static final int BUFFER = 2048;
public static void main (String argv[]) {
try {
String fileInput = argv[0];
String fileOutput = argv[1];

I have a Javascript COMserver code :
<script language="JScript">
var ComServer;
function CreateSQLAccServer () {
ComServer = new ActiveXObject('SQLAcc.BizApp');
[Code] ....
But, now i would like to move the javascript code into java application base system. I try :
ActiveXComponent Comserver = new ActiveXComponent("SQLAcc.BizApp");
but it having error and continue step how i do the checking see the Comserver is login or not?
I'm working on an assignment right now which involves passing a variable series of numbers to the Server to be sorted into the correct order and returned to the client.
So far I have it connecting to the server and asking for my numbers, and I am entering each number and pressing return, and it is accepting each number individually.
One (smaller I think) problem i'm having is with the client code, specifically the while loop.. I've tried to code it so that when I enter a full stop ('.') the program will stop asking me for more numbers and move on to sending them to the server.. but instead it just crashes giving an error.. heres an example
"Enter a number: 1
Enter a number: 3
Enter a number: 2
Enter a number: 1.
java.lang.NumberFormatException: For input string: "1."
at java.lang.NumberFormatException.forInputString(Num berFormatException.java:65)
[Code] ....
Here's the client code in full
package numberSortprogram;
import java.io.*;
import java.net.ServerSocket;
public class NumSortClient {
public static void main(String[] args) {
InputStreamReader is = new InputStreamReader(System.in);
[Code] ....
The big problem that I have is figuring out how to send the sorted array back to the client..
So, what im trying to get to happen is-
-Client is asked to enter numbers
-Client enters series of numbers into an array
-Array is converted to a string and sent to the server
-String is then split into an array of strings and sorted using compareTo (don't know if this is the best way?)
-Sorted array is sent back to client and displayed.
fyi this is making use of streamsockets..
All of the rest of my code is below:
package numberSortprogram;
import java.io.IOException;
import java.net.*;
import java.util.regex.PatternSyntaxException;
public class NumSortServer {
public static void main(String[] args) {
int serverPort = 4444; // default port
if (args.length == 1 )

Is there any option to access OBIEE server home page through java, without sending username and password through URL.
View Replies View RelatedI am currently writing two java classes (client and server). The client takes an input number form keyboard and sends it to the server. The server then multiplies this number by two and sends it back to the client. The numbers should also be printed to screen along the way, for example if I input the number 3 I should get
"From Client: 3" "From Server: 6"
They should continuously do this unless a negative number is received by the client, say for example the number -3 is sent to the server and it returns -6.
The code I have for the two classes so far is:
import java.io.*;
import java.net.*;
import java.nio.ByteBuffer;
import java.util.Scanner;
class Client {
public static void main(String args[]) throws Exception {
DatagramSocket clientSocket = new DatagramSocket();
[Code] .....
Currently, when I run the program all I get is an output of the number first entered. I am aware it requires a loop but I don't know where and what the condition should be.
Also if I wanted to adapt this so that it would take the integer from client and subtract two at the server and return to client who sends back to server to keep subtracting two unless it reaches a negative number at which point the client will terminate the program - how might I do this.
I do realise there needs to be a while loop in the above code, but I wanted to test it sent the number from client to server and its not doing it. All I get is a print screen of 'enter number' and then the number I enter.
Code structure :
Server : Java Servlet
Client : Simple JSP
Communication : Server Sent Events every 1 second
Here is the problem.
My code needed the server to send updates every one second to the client as stated above. Hence, I added a while loop with a sleep of 1000 milliseconds in the servlet code as shown below. The following strange behavior is observed:
- While the server is sending updates to the client, and the client window closes by mistake, the server does not stop sending updates It continues sending the data.
- When the client is re-opened, it sends data much faster (almost double). For example, the server sends 60 seconds worth of updates (60 updates) in just 25-30 seconds. The server sends faster updates not only for this round of updates, but also for any subsequent updates.
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException {
PrintWriter writer = null;
try{
[Code]......
This server behavior is much unexpected. Am I writing the server side code wrong? I have looked around a lot and only found while loop method for modifying the server update interval. Is there any other method which I am missing?
