    Eclipse (software) 1 Eclipse (software) Eclipse Screenshot of Eclipse 3.6 Developer(s) Free and open source software community Stable release 3.6.2 Helios / 25 February 2011 Preview release 3.7M6 / 10 March 2011 Development status Active Written in Java Operating system Cross-platform: Linux, Mac OS X, Solaris, Windows Platform Java SE, Standard Widget Toolkit Available in Multilingual Type Software development License Eclipse Public License Website [1] Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, Ruby (including Ruby on Rails framework), Scala, Clojure, and Scheme. The IDE is often called Eclipse ADT for Ada, Eclipse CDT for C/C++, Eclipse JDT for Java, and Eclipse PDT for PHP. The initial codebase originated from VisualAge.[2] In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its abilities by installing plug-ins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Released under the terms of the Eclipse Public License, Eclipse is free and open source software. It was one of the first IDEs to run under GNU Classpath and it runs without issues under IcedTea. Eclipse (software) 2 Architecture Eclipse employs plug-ins in order to provide all of its functionality on top of (and including) the runtime system, in contrast to some other applications where functionality is typically hard coded.

It allows Python to make use of Java only libraries, exploring and visualization of Java structures, development and testing of Java libraries, scientific computing, and much more. By gaining the best of both worlds using Python for rapid prototyping and Java for strong typed production code, JPype provides a powerful environment for engineering and code development. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both virtual machines. This shared memory based approach achieves decent computing preformance, while providing the access to the entirety of CPython and Java libraries. Contents 1 JPype Documentation, Release 0.7.0 2 Contents CHAPTER 1 Parts of the documentation 1.1 Installation JPype is available either as a pre-compiled binary for Anaconda, or may be build from source though several methods. 1.1.1 Binary Install JPype can be installed as pre-compiled binary if you are using the Anaconda Python stack. Binaries are available for Linux, OSX, ad windows are available on conda-forge.

  • Introduction Background Scope
    Copyright Oracle Corporation and VMware Inc, 2010 Enterprise Modules Project (Gemini) Proposal The Enterprise Modules Project is a proposed open source project under the Eclipse Runtime Project. This project is in the Project Proposal Phase (as defined in the Eclipse Development Process). Introduction The intent of the "Enterprise Modules" project, nicknamed Gemini, is to provide a home for subprojects that integrate existing Java enterprise technologies into module-based platforms, and/or that implement enterprise specifications on module-based platforms. Gemini will be a parent ("container project" as defined by the Eclipse Development Process) for several subprojects ("operating projects" as defined by the Eclipse Development Process) that provide the specific implementations/integrations. Gemini will itself be a subproject of the Eclipse Runtime Project and will strive to leverage functionality of existing projects. We encourage and request additional participation and input from any and all interested parties in the Eclipse community. Background Enterprise applications are often complex, involving multiple layers and many actors. Even though every application has a different purpose and usage, there are a number of features and behavioral requirements in the underlying infrastructure that are common among many of those seemingly dissimilar applications. For a long time, not only did developers need to create the vertical business logic of the application, but they also had to create the platform plumbing on which the application could run. Enterprise Java standards made great strides in defining specifications describing how these layers could be implemented, exported and used. They have since become the assumed and ubiquitous underpinnings of the majority of enterprise Java systems.
