Free j2se software for linux

Registry J2SE is a library that provides lightweight registry functions for both Hibernate2 and Hibernate3 configurations.

The Jesktop project is a desktop system written in Java that can have GUI applications installed into it. It is semi-dependant upon NanoContainer which is a component framework at Codehaus. NanoContainer and Constructor Dependency Injection are going to change the way we think of Java based component computing.
Jesktop has been under construction since November 2000. Its team was founded by people building Williams Portable Java Environment (PJE) since early 2000.
- To have a fully functional Java desktop environment running on a fully functional Java operating system that is portable across a number of host operating systems, or if there is JDK support in a BIOS layer, without a host operating system.
- To have a single CD installation of Linux (or other Java capable OS) without its own applications, but with NanoContainer, Jesktop and many Java apps pre-configured.
- To see the Jesktop and NanoContainer used widely by Java enthusiasts and deployed on yet to be created Network appliances and palm sized devices (when palm sized devices support J2SE). Thats right, we see this running on small devices. The attraction to hardware manufactureres is obvious - a standard open source OS layer that can support multiple applications safely.
- To see thousands of GPL, MPL, SPL, Commercial etc. etc. apps runnable inside Jesktop. All will be hot installable, reinstallable and de-installable. No reboot/restart necessary. No questions asked.
Main features:
- Multiple GUI applications running inside the same virtual machine.
- Multiple server applications running inside the same virtual machine.
- Drag and drop between applications (to finish)
- Mime type associations for applications (to finish)
- Many built-in, bundled and ported applications.
- Plugable Window Managers.
- Hot installable applications. Hot deinstallable and reinstallable too.
- Externally skinable applications. Apps dont need their own skin logic.

JBother is a Jabber client written in pure Java (1.4.x). It supports groupchat in a tabbed window, multiple resources, transport registration (so you can get on AIM, MSN, Yahoo!, and ICQ through JBother), sounds for different events, has several different skins, and should run on any platform that has the JRE installed (I have personally seen it working on Windows, Linux, FreeBSD, Solaris, and OS X).
JBother project has a plugin system that allows us to write code that is specific to a certain platform, while keeping the core pure Java. An example is the Win32 plugin - it allows for an icon in the system tray on Windows. All plugins can be easily viewed and installed from within JBothers plugin manager.
Installation:
1) You MUST have java 1.4.x or greater! Java 1.3.x will not work! Get it at java.sun.com/j2se
2) You unzip the zip file. I know youve already done that because you are reading this text.
3) Run JBother.jar like this: java -jar JBother.jar, or in Windows just double click on it.
4) Create an account on jabber.org or linuxhelp.homeunix.com if you havent already got a jabber account
5) Have fun!
Enhancements:
- This release includes improvements to file transfer support and support for JEP-0144 (roster exchange).

swIMP short from SWIG-based Interfaces for Mathematical Programming aims at making solvers written in C or C++ available under other languages.
The current focus is on Java as target language and on LP/IP-solvers which are compatible to the Open Solver Interface (OSI) from the Coin-OR-project. This includes both Open Source solvers as well as reknown commercial solvers like CPLEX and Xpress (see Features).
The wrappers are implemented using the generator tool SWIG. SWIG generates both C++ code which is then compiled into a shared library and Java-code which accesses the shared library through the Java Native Interface (JNI).
In principle, SWIG also supports other target languages like Python or Perl but this would require non-trivial modifications of the SWIG interface definitions currently provided by swIMP.
Main features:
Java-wrappers for OSI-compatible solvers
- The following solvers are currently supported:
Solvers from the Coin-OR-project, namely
- Clp,
- Cbc,
- Vol,
- Symphony.
- Support for the following solvers should be easy to add (at most one day of work or so) but has not yet been added because I had no need to - a short notice if you need such a feature or even better a patch for including one of these solvers would of course be highly welcome:
- GLPK,
- CPLEX,
- Xpress
Environment
- The generated Java-code has been compiled and tested under Version 1.4.2 of Sun Java 2 Platform, Standard Edition (J2SE) .
- The shared library is currently built and tested under Linux but should work on most UNIX systems. The GNU Build Tools (autoconf and automake) are used to achieve this portability. However, no tests on other platforms than Linux have been performed.
swIMP requires the following libraries from Coin-OR-project:
- libCoin,
- libCgl,
- libOsi.
- Furthermore, the libraries for the solvers which shall be accessed through Osi must be available, of course. For example, you may want to install
- libCbc, libCgl and libVol from the Coin-OR-project,
- together with their Osi-counterparts libOsiCbc, libOsiCgl and libOsiVol.
- The Lang and the Logging Components of Jakarta Commons,
- JUnit to execute the automatic unit test suite.
The build process uses the following tools (the version with which the build process has been tested is included in brackets):
- GNU Make (3.80)
- A C++ compiler (as selected by ./configure). We use gcc 3.3.4.
- Apache Ant (1.6.2)
- SWIG (1.3.24) if you want to rebuild the generated sources (see Installation).
Enhancements:
- First version with beta-status.
- New hand-tailored mapping for int[] and double[], such that the C++ code works directly on the Java-datastructures. No noticeable overhead compared to using SWIG-wrappers for standard C++ arrays.
- Planned functionality for first production release implemented.
- Test suite has reached comprehensive code coverage.

Mckoi SQL Database is a full featured SQL-92 relational database management system written in Java.

The software can operate as either a dedicated multi-client, multi-threaded database server, or can be used as an embedded database inside a Java application.

The engine is designed to be easy to use and maintain and versatile for sophisticated database development tasks. The software provides a JDBC 2.0 driver.

To use Mckoi SQL Database, you will need a JavaTM runtime environment version 1.2 or greater. Sun provides Java runtimes for Win32, Solaris and Linux from their website at http://www.javasoft.com/j2se/. IBM also provides various Java runtimes for a number of platforms at http://www.ibm.com/java/jdk/download/.

When Java has been installed on your system, unpack the mckoi distribution file to a directory in your file system. Then you are ready to create a database and develop your database application.

Creating A Database

Before you can begin development of your database application, you will need to create and configure a blank database. The database configuration file describes all of the configurable properties of the database (details of the database configuration file are covered in the next section). The software ships with a default configuration that looks for a database at path ./data in your filesystem.

To create a database using the default configuration with an admin username of admin_user and password aupass00, go to a prompt, change to the Mckoi Database distribution directory and type:

java -jar mckoidb.jar -create "admin_user" "aupass00"

We do not advise using either this username or password in a production system. The user created here has full control over every aspect of the database so choose a username / password carefully.

When the command has completed, a sub-directory called data will have been generated. This directory is used to store data from the database. A sub-directory called log is also generated which stores debugging and query log information.

Database Configuration

When you run the mckoidb.jar package, it looks for a file named db.conf in the current directory. This file contains a number of variables that determine where the database looks for information, as well as other user-definable properties. The configuration file can be renamed and copied to a different location. If you change the configuration file location, you must supply the location when you run the database;

java -jar mckoidb.jar -conf [location of conf file] .....

You can edit the configuration file with a text editor. The default configuration file that ships with the software contains extensive comments on what each variable does.
