GNU WebSocket4J is a WebSocket protocol implementation in Java. It allows you to build Web applications that interact with applications running in a JVM. GNU WebSocket4J implements both the server and client side of the protocol, so it can be used to build both WebSocket servers and clients.
Stab is a multi-paradigm, type-safe programming language. It will be familiar to Java and C# programmers. The compiler produces Java bytecode. Stab integrates features like lambda expressions, iterator blocks, language integrated queries, and more. It can directly use any existing Java libraries, and libraries written in Stab are directly usable from Java.
PHP-to-Scala Migration Helper is a tool that enables individuals and organizations with a significant PHP codebase to migrate to a Java-centric environment completely free of any PHP source code, PHP tools, PHP servers, and PHP developers. PHP-to-Scala Migration Helper is technically a PHP compiler, but it translates to readable, maintainable source code rather than machine code. Its goal is not to make PHP code run faster, but it is not an unwelcome side effect.
JCGO (pronounced as "j-c-go") translates (converts) programs written in Java into platform-independent C code that can be compiled (by third-party tools) into highly-optimized native code for the target platform. JCGO is a powerful solution that enables your desktop, server-side, embedded, mobile, and wireless Java applications to take full advantage of the underlying hardware. In addition, JCGO makes your programs, when compiled to native code, as hard to reverse engineer as if they were written in C/C++. The JCGO translator uses some optimization algorithms that allow, together with optimizations performed by a C compiler, the resulting executable code to reach better performance compared with the traditional Java implementations (based on the Just-In-Time technology). The produced executable does not contain nor require a Java Virtual Machine to execute, so its resource requirements are smaller than that required by a typical Java VM. This also simplifies the process of deployment and distribution of an application.
