Free java based application software for linux

CGI::Application is a framework for building reusable web-applications.

SYNOPSIS

# In "WebApp.pm"...
package WebApp;
use base CGI::Application;

# ( setup() can even be skipped for common cases. See docs below. )
sub setup {
my $self = shift;
$self->start_mode(mode1);
$self->mode_param(rm);
$self->run_modes(
mode1 => do_stuff,
mode2 => do_more_stuff,
mode3 => do_something_else
);
}
sub do_stuff { ... }
sub do_more_stuff { ... }
sub do_something_else { ... }
1;


### In "webapp.cgi"...
use WebApp;
my $webapp = WebApp->new();
$webapp->run();

CGI::Application is intended to make it easier to create sophisticated, high-performance, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve.

CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system or web server.

Calyxo Web Application Framework encourages in MVC model 2 based web application development.

It offers support for true modular applications, i18n, a flexible view manager, a powerful validation engine, and more! Calyxo is entirely written in Java and builds on the latest Servlet and JSP technologies.

The Calyxo project divides into several components

Calyxo Base - this component collects some of the basic, reusable classes used throughout all the other components. It introduces basic concepts like modules, i18n, accessors and so on...

Calyxo Control - this component implements the Calyxo controller. Calyxo uses an approach similar to Struts here, so Struts users should feel familiar with Calyxo from the start. Calyxo Control may be considered as the "main part" of the Calyxo platform.

Calyxo Forms - this component allows the definition of forms, along with all their validation steps and lets you map inputs to properties of a data object. Complex validations, dependencies between inputs and mapping an input to a set of properties are supported. The Calyxo Forms JSP tag library provides replacements for HTML elements related to forms.

Calyxo Panels - this component allows the definition of pages in a container/component manner. Pages are dynamically composed from a tree of page fragments. Panel definitions may be nested to arbitrary depth and may use inheritance.

Calyxo Struts - this component focuses on integrating Calyxo parts into the very popular Apache Struts framework. The Calyxo Panels and Calyxo Forms components may be used with Struts to replace Struts Tiles and the Struts Validator.

The Horde Application Framework is written in PHP, and provides the common tools a Web application requires: classes for dealing with preferences, compression, browser detection, connection tracking, MIME, and more.
The Horde Framework does not provide any significant end user functionality and it provides a base for other applications and tools for developers. You will probably want to install some of the available Horde applications, such as IMP (a webmail client), or Kronolith (a calendar).
Enhancements:
- This is a security release that fixes a cross site scripting vulnerability and improves protection against phishing attempts.

Pylon Application Platform is a free and open source platform for embedded applications.
Our mission:
- Our goal is to dominate the world.
- We consider Microsoft as our main competitor. The second our competitor is UAZ (Ulyanovsky Automobilny Zavod) which produces UAZ vehicles. That vehicle is just another way for user to be perfect.
- Pylon is designed by programmers and for programmers only.
- Pylons authors hate Java, Java applications, and Java programmers.
- Pylons authors like Apples creatures just a little bit.
- Pylons authors love Kubuntu.
- We decline any responsibility for any results of using Pylon.
- We do not recomend to use Pylon prior to version 0.2.0-alpha1 as a platform for Nuclear Power Plant control software.
- We do not recomend to use Pylon prior to version 0.5.0 as a platform for Automatic Washing Machine firmware.
- Pylon is a way to be perfect. Nothing more
Main features:
- Pylon is absolutely free either for commercial or for any other purpose.
- It is written in pure C and C++.
- It is for Linux only.
- It is a scriptable platform. That means that Pylon-based application will be scriptable. Pylon uses Forth as a scripting language.
- Pylon-based application is supposed to be a single thread application.
- Pylon provides a non-preemptive multitasking.

Jagzilla is simply the Java version of bugzilla. The idea of this project is:
- To provide a complete java-based interface to bugzilla
- To facilitate interoperation between bugzilla and java based apps
- To provide additional functionality to bugzilla while mantaining compatibility
Main features:
- Bugzilla and java based apps integration
- Bugzilla and eclipse integration (with the eclipse plugin)
- Bugzilla and cvs integration (with the eclipse plugin)
- Bugzilla extended functionality mantaining backwards compatibility (with jagzilla extension tables)
Components:
Hibernate Mapping
- This components includes java classes that represent rows in bugzilla tables, as well as mapping files. This provides direct hibernate access to bugzilla database.
Jagzilla Core API
- The core api is a higher abstraction level than hibernate mapping, which understands buisiness logic and provides an easy access to this funcionality.
Jagzilla Web Services API
- The web services API is actually the core api implementation which uses xml and http as transport. see rest-webapp
WS Client lib
- This is a simple jar to enable easy access to jagzilla WS from any java app.
Jagzilla mail processor
- A program to read email accounts and add bugs to database with information found on these mails.
Hibernate Client lib
- This is a simple jar to enable easy access to jagzilla Core API from any java app.
Eclipse plugin
- This plugin enables using most functionallity of jagzilla. The access can be with hibernate and JDBC (directly to the database) or via web services.
Webapp
- This is the web frontend for jagzilla. This web application shows how to use the jagzilla backend to provide a java web based front-end.
REST Webapp
- This web application is the server for the web services (in a simple sense of xml over http) interface.

Bulk Meter Flow and Operations provides a Web-based application to manage water meter readings.

Java 2SE technology readily harnesses the power of the network because it is both a programming language and a selection of specialized platforms.
As such, it standardizes the development and deployment of the kind of secure, portable, reliable, and scalable applications required by the networked economy.
Because the Internet and World Wide Web play a major role in new business development, consistent and widely supported standards are critical to growth and success.
The Java programming language lets you write powerful, enterprise-worthy programs that run in the browser, from the desktop, on a server, or on a consumer device. Java programs are run on -- interpreted by -- another program called the Java Virtual Machine (Java VM).
Rather than running directly on the native operating system, the program is interpreted by the Java VM for the native operating system. This means that any computer system with the Java VM installed can run a Java program regardless of the computer system on which the application was originally developed.
The Java platform is a software-only platform that runs on top of other hardware-based platforms. Because hardware-based platforms vary in their storage, memory, network connection, and computing power capabilities, specialized Java platforms are available to address applications development for and deployment to those different environments.
Java technology has grown to include the portfolio of specialized platforms listed below. Each platform is based on a Java VM that has been ported to the target hardware environment. This means, for example, in the case of Desktop Java, desktop applications written in the Java programming language can run on any Java VM-enabled desktop without modification.
Java 2 Platform, Standard Edition (J2SE), provides an environment for Core Java and Desktop Java applications development, and is the basis for Java 2 Platform, Enterprise Edition (J2EE) and Java Web Services technologies. It has the compiler, tools, runtimes, and Java APIs that let you write, test, deploy, and run applets and applications.
Enhancements:
- Olson time zone data was updated to version 2007e.
- Solaris-specific I/O interruption in response to thread interruption can now be switched off.
- Many bugs were fixed.
