Free cross platform java software for linux

Cross Platform Toolkit Library (xtklib) is a C++ based framework for highly object-oriented cross-platform programming.
In particular, the library provides a full abstraction layer between its API and the main services offered by the underlying operating system(Thread, processes,GUI,Filesystem,etc.) plus a set of generic utilities (Strings,Data structures,etc.).
Unlike other famous libraries, xtklib makes full use of all features of C++ like RTTI, Templates, Exceptions thus obtaining a strongly object-oriented design with a Java-like sensation.
The library is composed by two main modules: "Base" and "Widgets". The target operating systems are Windows and Unix(Linux and BSD in primis) with a plan to move also towards other systems.
Main features:
- Use of modern C++ - use of many powerfull features offered by modern C++ like exceptions,RTTI,templates and namespaces allows faster development,improves code readability,and reduces programming errors.
- Strong Object-Oriented design - designed to meet requirements of modern software industry: modularity, low coupling, high cohesion,information hiding. Design patterns and advanced class hierarchies are extensively used in all the library.
- Ease of use - Clean and intuitive programming interface with a Java-like sensation.
- Complete - Features supported includes:
- Basic services: Thread, Synchronization, Filesystem access, Processes, Networking.
- Advanced services: I/O Streams, Logging.
- Debugging tools: Stack tracing, Memory Leak detection.
- Gui widgets (Work in progress): Windows,Frames,Layout managers,common controls,advanced controls.
- Generic utilities: complete data structures framework, String class with unicode support.
- Full unicode support: native support to unicode, conversion to/from different charsets.
- And many others: the list is too much long to enumerate all minor but extremely usefull features.
- Cross Platform - Supports various systems and compilers.
- XTKlib is known to work under:
- Windows XP (x86)
- Visual C++ versions 7.1, 8.0
- MinGW32
- Linux (x86, x86_64)
- GCC 3.4
- Compatibility with other platforms and compilers are not excluded.(If you can compile/use xtklib with a non listed compiler/platform let us know about that, thanks)
- Fast - Although performance are not the main goal of this library (exceptions and RTTI have a tradeoff in this meaning), code agility and execution speed are often taken in consideration during development, thus leaving a performance advantage compared to interpreted programming languages(eg. Java,C#) or scripting languages(eg. Python,Ruby,Perl).
Enhancements:
- This is the first release with a working "Widgets" module, although it has only basic features.
- This release is provided for testing and development only.

Sun Java Platform Enterprise Edition (Java EE) is the industry standard for developing portable, robust, scalable, and secure server-side Java applications.

Building on the solid foundation of Java SE, Java EE provides Web services, component model, management, and communications APIs that make it the industry standard for implementing enterprise class service-oriented architecture (SOA) and Web 2.0 applications.

tpm4java is a library for accessing trusted platform modules in your Java applications.

tpm4java runs on Linux and Windows systems and can use version 1.1b and version 1.2 TPM modules.

Nemesis Pascal is an Pascal interpreter that is:

Free
Open Source (GPL)
Cross-platform (currently Windows and Linux)

Nemesis Pascal is written in Delphi and Kylix. Borland CLX libraries supplies the cross-platform features.

The Nemesis Pascal applications runs on Windows using native controls, and Linux using the CLX Library (a binding to Qt Trolltech).

Exemple:

unit test1;

interface

implementation

procedure main;
begin
ShowMessage(Hello World!);
end;

end.

BushSweeper is a clone of minesweeper game and it is cross platform. Clone of minesweeper game but you sweep bushs from your country. It was programmed in C++ and used FLTK GUI library cross platform.

DoxMentor4J is a standalone cross platform Web/Ajax based documentation library that is fully searchable and may be hosted in the file system, in an archive or embedded in the Java classpath.

Users create the library content structure and copy any online books or manuals into directories in the library structure. DoxMentor4J then provides a dedicated web server which presents the library as a tree structure on a web page. Users can navigate through the tree to locate online books. The tree is AJAX based so there is no large initial download of all the nodes in the content structure, instead the nodes are downloaded as they are opened.

Because DoxMentor4J is a cross platform Java based application, user can write their online library to CD/DVD or flash and have it available wherever they go on different machines and operating systems.

The web server framework classes used by DoxMentor4J is called HttpdBase4J and it supports content inside archive files or in jar and zip files in the Java classpath. The content can therefore be hosted in one compressed file, and as many documentation files are often text based this means the space saving can be meaningful. Additionally it can be more convenient to have all the content in one file.

This software also supports full text indexing and searching of content using the Lucene library. Content indexing may be enabled/disabled on a node by node basis. Search indices can be accessed inside an archive or on cd/dvd. The indexing code currently supports text, html, pdf, chm and djvu.
