Building Openjfx
Building OpenJFX Building a UI toolkit for many different platforms is a complex and challenging endeavor. It requires platform specific tools such as C compilers as well as portable tools like Gradle and the JDK. Which tools must be installed differs from platform to platform. While the OpenJFX build system was designed to remove as many build hurdles as possible, it is necessary to build native code and have the requisite compilers and toolchains installed. On Mac and Linux this is fairly easy, but setting up Windows is more difficult. If you are looking for instructions to build FX for JDK 8uNNN, they have been archived here. Before you start Platform Prerequisites Windows Missing paths issue Mac Linux Ubuntu 18.04 Ubuntu 20.04 Oracle Enterprise Linux 7 and Fedora 21 CentOS 8 Common Prerequisites OpenJDK Git Gradle Ant Environment Variables Getting the Sources Using Gradle on The Command Line Build and Test Platform Builds NOTE: cross-build support is currently untested in the mainline jfx-dev/rt repo Customizing the Build Testing Running system tests with Robot Testing with JDK 9 or JDK 10 Integration with OpenJDK Understanding a JDK Modular world in our developer build Adding new packages in a modular world First Step - development Second Step - cleanup Before you start Do you really want to build OpenJFX? We would like you to, but the latest stable build is already available on the JavaFX website, and JavaFX 8 is bundled by default in Oracle JDK 8 (9 and 10 also included JavaFX, but were superseded by 11, which does not). -

Applets, Servlets and JSP
Java Programming : applets, servlets and JSP. SR03 Dritan Nace A summary of Java Java is a language developed by Sun, which is designed to be object oriented and Simple, robust and secure, independent of hardware architectures and Multitasking. Object oriented and simple : Simpler than C++, transparent memory managment… Robust et secure : Data typing is extremely strict. For applets, it is in principle impossible to access the resources of the host machine. Independant of hardware architectures : The compiler generates a universal code : the « byte-code ». An interpreter which is specific to the host machine, « virtual machine », executes the programs. Multitasking : Java seemingly allows execution of several processes. In reality, a time slot is given to each process on the processor (Multithreaded). J2SE versus J2EE J2SE (standard edition) contains the basic usable components from both the client and server side, – GUI, AWT/Swing for applications (client) or applets. Currently J2SE v1.6 (ou V6) J2EE (enterprise edition), is in a certain sense an extension of SE, designed for server side programming – Servlets, JSP, EJB, etc. • Currently J2EE v1.4 Java and object oriented programming • Classes, and objects – The objects include data and processing for the data. Communication is done via messages (methods). – A class corresponds to an abstract model for object construction. A class is made up of: • attributes (static part) • Methods (dynamic part), which define the behaviour. – Inheritance : the « is a » relationship : a car is a vehicule, – Polymorphism : the same message can be recognised by several objects and entail different behaviour. Portability: JVM The compiler compiles the java source in byte code : javac car.java => car.class Then, java is the name of the program which will interpret the generated byte code. -
Abstract Window Toolkit Overview
In this chapter: • Components • Peers 1 • Layouts • Containers • And the Rest • Summary Abstract Window Toolkit Overview For years, programmers have had to go through the hassles of porting software from BSD-based UNIX to System V Release 4–based UNIX, from OpenWindows to Motif, from PC to UNIX to Macintosh (or some combination thereof), and between various other alternatives, too numerous to mention. Getting an applica- tion to work was only part of the problem; you also had to port it to all the plat- forms you supported, which often took more time than the development effort itself. In the UNIX world, standards like POSIX and X made it easier to move appli- cations between different UNIX platforms. But they only solved part of the prob- lem and didn’t provide any help with the PC world. Portability became even more important as the Internet grew. The goal was clear: wouldn’t it be great if you could just move applications between different operating environments without worr yingabout the software breaking because of a different operating system, win- dowing environment, or internal data representation? In the spring of 1995, Sun Microsystems announced Java, which claimed to solve this dilemma. What started out as a dancing penguin (or Star Trek communicator) named Duke on remote controls for interactive television has become a new paradigm for programming on the Internet. With Java, you can create a program on one platform and deliver the compilation output (byte-codes/class files) to ever yother supported environment without recompiling or worrying about the local windowing environment, word size, or byte order. -

Eclipse (Software) 1 Eclipse (Software)
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.
