Free jars software for linux

Jar::Signer Perl module ease the process of creating a signed Jar file.

SYNOPSIS

# using FindBin is just a suggestion.
use FindBin qw( $RealBin );
use Jar::Signer;
my $signer = Jar::Signer->new;
# location of the keystore, created if needed.
$signer->keystore("$RealBin/MyKeyStore");
# dname properties of the certificate.
$signer->dname("CN=Mark Southern, O=My Corporation, L=My State, C=USA");
# name for .fingerprint and ..cert files, created if needed.
$signer->alias("$RealBin/MyCert");
# the Jar file that we want to sign.
$signer->jar(shift);
# if signed_jar is undefined then the default is basename.signed.jar where basename is the basename of the Jar file.
$signer->signed_jar(shift);
# create the signed Jar.
$signer->process;

This module, and the script that uses it make it a lot simpler to generate signed Jar files for use in Java applets etc. It steps through all the needed jar, jarsigner and keytool command lines.

Java Tetris project is a simple Tetris game.
Java Tetris is a game written with Eclipse and the VE Plugin. It is a nice starting point if you want to learn Java and Eclipse.
The game can be started as Java applet or Java application.
Enhancements:
- The dependency on jdom was removed.
- The jar is now only 30kb.
- A bug was fixed in the score list.

jAscom is a Wrapper around the JACOB (JAva-COM Bridge) libraries for an easy access to the ASCOM Platform 3.0 out of Java. The project provides the whole functionality (methods, properties) of the ASCOM Telescope API Version 2.

Minor bugfix release. Alpha2 now includes the Focuser-, and Dome API, too.

This means easy and fast coding of java-applications for all sorts of telescope-controlling problems you can imagine, using a widely accepted standard.

Installation instructions:

1. Download and install ASCOM Platform 3.0 Full Setup.

2. Download jacob.dll from http://danadler.com/jacob/ found in the JACOB binary distribution 1.7.

There is a newer version located in the FILE-Section at http://groups.yahoo.com/group/jacob-project/ (jacob_jre142fix_bin.zip).

This version could also be found in http://home.textdesign.com/jeamy/jascom/jacob_dll.jar (use java -xf jacob_dll.jar jacob.dll to extract it).

Add jacob.dll to your Path.

3. Download the jAscom Distribution. Exctract it into a directory of your choice (jar -xf jascom.jar).

4. Compile the files, start your Telescope Driver and connect it to the Telescope or use the ASCOM Telescope simulator (preferred for testing).

Excecute com.jeamy.jascom.test.JAscomTest for some tests/examples.

(Alternative you can start the binary version of JAscomTest with java -jar jascom.jar)

5. Create your Application using jAscom. Examples are shown in com.jeamy.jascom.test.JAscomTest, com.jeamy.jascom.test.JAscomDomeTest and com.jeamy.jascom.test.JAscomFocuserTest.

Camera_AXIS is a Java application for viewing images generated by an AXIS 2100 network camera. The camera generates a video stream in MJPG format.

The java source code can be browsed online or downloaded in tgz format. The application uses the Base64 encoder from Robert Harder (distributed with Camera_AXIS). Installation is simple:

make

Start the application using te command:

make test

Configuration parameters are saved in .java.cfg. This file is created the first time you start the application and contains the URL of the camera and the user id and password of the camera administrator. Without the id and/or the password, you can still view images from the camera, but you wont be able to change its settings. Proxy settings are taken from the http_proxy environment variable (if present).

A precompiled jar-file is also available. Execute it with java -jar AXIS.jar.

jjjuste is a Java/Jack port/rewrite of JustePort. It contains Java classes for streaming data to an Apple Airport Express. The project also contains a Jack client that allows the streaming to be integrated within a Jack audio flow.
The functionality of the basic client is more restricted than JustePort (only raw data at maximum volume), but the Jack integration gives more reliable playback on Linux and the structure of the code has been clarified (if you want to port JustePort to another language I suspect its easier to use jjjuste than JustePort, but I may be biased).
In case the above is not clear, jjjuste contains:
- a basic Java based client that can stream audio data to an Airport Express
- simple integration with Jack, which is an audio server for Linux.
This means that (almost) any audio source playing on Linux can be routed to the Airport (and so played on your hifi, remotely).
Usage:
- Get Jack running
- Download JJack from CVS (it is important you use the very latest CVS code - I committed a patch on 2007-07-10).
- Compile and install JJack (unpack, cd make, ant)
- Download Bouncy Castle and Apache Commons Codec jars
- Download the jar
- Start the client with
java -classpath jjjuste-1.0.jar:[other jars]
-Djava.library.path=[path to directory containing libjjack.so]
org.acooke.jjjuste.jack.FiniteJackClient [airport address]

jHamachi project is a Linux GUI for the Hamachi VPN client. It is still a work in progress and your contributions will help to improve it.

Running jHamachi

You still need the hamachi client, which you can get here. Once it is installed, you can download jHamachi and run it by typing java -jar jHamachi.jar.

You need at least Java 1.5. If the client cant connect, check your tun settings. Make sure you followed the instructions in the readme file. In most cases, running tuncfg as superuser should help.

bcr steps is a step sequencer and arpeggiator made for the Behringer BCR2000 controller. The project can also be used on its own, or with almost any other MIDI controller.

If you like, you can try out the applet version, though it wont give you the full MIDI capabilities of the standalone application.

Instructions:

Download and run with java -jar bcr-steps.jar

Fair DJ is an Mserv-compatible music server designed to play music in a room with several users sharing a set of speakers.

The users can rate songs, and Fair DJ selects songs using these ratings and a fairness algorithm to ensure that everybody is happy.

FairDJ is an extended version of Mserv, written in the Java programming language.

Installation:

Starting fairdj for the first time will create a settings file in your users home directory. FairDJ will print out a helpful location message specifying the path to this file. Since you most likely want to edit this file before starting Fair DJ for real, weve included a helpful install option which simply exits after creating the settings file.

Start FairDJ with the following command line:

java -jar fairdj.jar -install

FairDJ should exit after logging a message specifying where the settings file was written. To specify another location for this settings file, use the settings option:

java -jar fairdj.jar -settings < settings file >

Edit the settings file by hand, using your favourite XML/Text editor, to point to wherever you want to store your ratings, where your music is, and where your user database should be. The settings file is fairly well commented and should provide you with the information you need to configure your Fair DJ installation. The new user database will be empty, and only the default user and password, as specified in the settings file, will be valid.

To get help on the available options, use the help option:

java -jar fairdj.jar -help [< option >]

To connect to FairDJ, connect with a telnet client to the specified port (default 4444), for example:

telnet localhost 4444

Log in with your default user and password. To get help on the available commands in FairDJ, type "help" followed by enter in the telnet client.

Start by creating a superuser (master), and a user for yourself. They can be the same if you want to. Here is an example:

create myuser mypass MASTER
