Jython
Jython is an implementation of the Python (programming language), Python programming language designed to run on the Java (programming language), Java platform. It was known as JPython until 1999. Overview Jython programs can import and use any Java class. Except for some standard modules, Jython programs use Java classes instead of Python modules. Jython includes almost all of the modules in the standard Python (programming language), Python programming language distribution, lacking only some of the modules implemented originally in C (programming language), C. For example, a user interface in Jython could be written with Swing (Java), Swing, Abstract Window Toolkit, AWT or Standard Widget Toolkit, SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on demand or statically. History Jython was initially created in late 1997 to replace C (programming language), C with Java (programming language), Java for performance-intensive code accessed ...

Wsadmin
The wsadmin tool is a command shell for the purpose of performing systems administration on all the artifacts in an IBM WebSphere Application Server (WAS) cell. It gets its name from the name of the shell script that invokes this command shell. This command shell can execute connected to a WAS cell or completely disconnected from a WAS cell (local mode). The wsadmin tool can be used to execute scripts written in Jacl and Jython, or it can be used interactively to execute individual commands. These scripts and commands perform administrative tasks like application deployment, configuration changes and run-time monitoring and control of IBM WAS. History of WebSphere Application Server command shells The ''wscp'' stands for WebSphere Control Program. It was used in older versions of WAS like Version 4.0 and Version 3.5. The ''wsadmin'' command shell replaced ''wscp'' in WebSphere Application Server Version 5.0 and all subsequent versions. It can perform almost all of the tasks ...

Python (programming Language)
Python is a high-level programming language, high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is type system#DYNAMIC, dynamically type-checked and garbage collection (computer science), garbage-collected. It supports multiple programming paradigms, including structured programming, structured (particularly procedural programming, procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC (programming language), ABC programming language, and he first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZK Framework
ZK is an open-source Ajax Web application framework, written in Java, that enables creation of graphical user interfaces for Web applications with little required programming knowledge. The core of ZK consists of an Ajax-based event-driven mechanism, over 123 XUL and 83 XHTML-based components, and a mark-up language for designing user interfaces. Programmers design their application pages in feature-rich XUL/XHTML components, and manipulate them upon events triggered by end user's activity. It is similar to the programming model found in desktop GUI-based applications. ZK uses a server-centric approach in which the content synchronization of components and the event pipe-lining between clients and servers are automatically done by the engine, and Ajax plumbing codes are completely transparent to web application developers. Therefore, the end users get the similar engaged interactivity and responsiveness as a desktop application, while programmers' development retains a similar ...

List Of JVM Languages
This list of JVM languages comprises notable computer programming languages that are used to produce computer software that runs on the Java virtual machine (JVM). Some of these languages are interpreted by a Java program, and some are compiled to Java bytecode and just-in-time (JIT) compiled during execution as regular Java programs to improve performance. The JVM was initially designed to support only the language Java. However, over time, additional languages were adapted or designed to run on the Java platform. JVM languages High-profile languages As of 2024, according to the TIOBE index of the top 100 programming languages, and PyPL, the top JVM languages are: * Java (#3, at one point at #1; #2 at PyPL), a statically-typed object-oriented language * Kotlin (#21, at one point at #18; #13 at PyPL), a statically-typed language from JetBrains, the developers of IntelliJ IDEA and Google's preferred language for Android * Scala (#26, at one point at #20; #22 at P ...

Command Line Interface
A command-line interface (CLI) is a means of interacting with software via commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utilities still provide CLI. A CLI enables automating programs since commands can be stored in a script file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI include a GUI (including the desktop metaphor such as Windows), text-based menuing (including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Virtual Machine
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK. JVM specification The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection ...

Reference Implementation
In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is a program that implements all requirements from a corresponding specification. The reference implementation often accompanies a technical standard, and demonstrates what should be considered the "correct" behavior of any other implementation of it. Characteristics and examples Reference implementations of algorithms, for instance cryptographic algorithms, are often the result or the input of standardization processes. In this function they are often dedicated to the public domain with their source code as public domain software. Examples are the first CERN's httpd, Serpent cipher, base64 variants, and SHA-3. The Openwall Project maintains a list of several algorithms with their reference source code In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CPython
CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. CPython can be defined as both an interpreter and a compiler as it compiles Python code into bytecode before interpreting it. It has a foreign function interface with several languages, including C, in which one must explicitly write bindings in a language other than Python. Design A particular feature of CPython is that it makes use of a global interpreter lock (GIL) such that for each CPython interpreter process, only one thread may be processing bytecode at a time. This does not mean that there is no point in multithreading; the most common multithreading scenario is where threads are mostly waiting on external processes to complete. This can happen when multiple threads are servicing separate clients. One thread may be waiting for a client to reply, and another may be waiting for a dat ...

Ghidra
Ghidra (pronounced GEE-druh; ) is a free and open source reverse engineering tool developed by the National Security Agency (NSA) of the United States. The binaries were released at RSA Conference in March 2019; the sources were published one month later on GitHub. Ghidra is seen by many security researchers as a competitor to IDA Pro. The software is written in Java (programming language), Java using the Swing (Java), Swing framework for the Graphical user interface, GUI. The decompiler component is written in C++, and is therefore usable in a stand-alone form. Scripts to perform automated analysis with Ghidra can be written in Java or Python (programming language), Python (via Jython), though this feature is extensible and support for other programming languages is available via community plugins. Plugins adding new features to Ghidra itself can be developed using a Java-based extension framework. History Ghidra's existence was originally revealed to the public via Vault 7 i ...

Java Bytecode
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. Each instruction is represented by a single byte, hence the name bytecode, making it a compact form of data. Due to the nature of bytecode, a Java bytecode program is runnable on any machine with a compatible JVM, without the lengthy process of compiling from source code. Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations. Relation to Java In general, a Java programmer does not need to understand Java bytecode or even be aware of it. However, as suggested in the IBM developerWorks journal, "Understanding bytecode and what bytecode is li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
