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'm facing some problem connecting to a IBM 4690 OS Server with the FTPClient class from the commons-net-1.4.1 library. It seems it can't read the folder on the server. The problem is that using the FTP client from Internet Explorer is works perfectly.
Here is my code (kind of hardcoded but it's only to test).
Here is the ParserInitializationException that it throws:
org.apache.commons.net.ftp.parser.ParserInitializationException: Unknown parser type: OS 4690 operating system at org.apache.commons.net.ftp.parser.DefaultFTPFileEntryParserFactory.createFileEntryParser(DefaultFTPFileEntryParserFactory.java:118) at org.apache.commons.net.ftp.FTPClient.initiateListParsing(FTPClient.java:2358) at org.apache.commons.net.ftp.FTPClient.listFiles(FTPClient.java:2141) ...
I've tried to use many of the FTPFileListParser available but without success. How could I handle the problem? Where could I find a Parser that would works?
I want to develop a dynamic webpage (using JSP & tomcat hosted on windows server) which will connect to unix server and on button "Show Files" click on dynamic webpage it should display all the files present in the unix server.
The button click should display the files which i can see when i run "ls -ltr" in unix server home directory.
I've been provided a code skeleton for what must be done, but despite my best efforts to make things work, I'm coming up dry (obviously, due to a lack of knowledge.) One thing that might work is if I knew how to debug this type of application, line-by-line, to see exactly what is going on. Obviously, it's easy enough to debug the client part, but moving over to the server part, I haven't been able to figure that out (I'm using Eclipse.)
I took an example from here on client server sockets: Complete Java Networking Explained with Simple Examples - Go4Expert and placed it in separate classes and had a single main to run it both a server then the client.It seems ok but I cannot have the console outputs sharing the same console.
I start the server first and this takes precedence and the client will not output to console unless I stop the restart the app after commenting out the server startup as its already running, then eclipse gives me 2 consoles I can move between Is it possible to have both client and server share output console?
I am trying to learn how to connect to web sites using java. Someone suggested that I learn to "consume an API with java". They also suggested that I practice through a weather website called weather underground and sent me a link [URL] .... I would like to know how to connect to this site to get weather information.

If yes what extra knowledge i should know ? How can i connect it ? and what books are good for it ?

I'm programming a game in Eclipse using Java for Android. I was wondering if any good example of a Health bar using Images. All I can find is people using the progress bar, but i feel that's unprofessional looking.
My goal is to layer 2 images. 1 being the frame of the health bar, 1 being the value of the health bar. I figured it would be something like moving the value health bar image few pixels over depending on the variable of health.
I am following a tutorial to write a 2d game from scratch in java but when I compile and run my code the application (JFrame) doesn't come up on my screen, it just runs for a second and terminates itself for some reason.
package com.thecherno.rain; import java.awt.Canvas; import java.awt.Dimension; import javax.swing.JFrame; public class Game extends Canvas implements Runnable{ private static final long serialVersionUID = 1L;
im wanting to create a console gui that opens with my program game and people can type stuff in it to run commands as well as a debug option to show when errors happen and have a command to list all availble command.
try to make a game in this code i am trying to make the basics i have made a mouse it should move the game code is
