OpenXava is a framework to develop AJAX JavaEE/J2EE applications rapidly and easily. It allows you to define applications only with POJOs, JPA, and Java 5 annotations. It is feature rich and flexible. It generates JSR-168 portlet applications (Liferay, WebSphere Portal, Jetspeed, etc.).
The JET Code Generator connects to any JDBC-based database and exports the schema as an XML-formatted file, and then generates code based on XSL Transformations. The user is free to write/modify XSLTs to generate virtually any type of source code from the XML representing your database schema. A complete example is included with a database, support classes, XSL Transformations, and build scripts (ANT and batch).
gtklean is a C header file generated directly from the GTK+ headers to provide a visually cleaner and less error prone C API for GTK+. It eliminates gtk_ prefixes in front of every GTK+ function. It automatically inserts calls to the type checking and casting macros for arguments that require them (e.g. GTK_WIDGET() and GTK_SIGNAL_FUNC()) so you can't forget them and never need to see them. It also replaces the string literals used for signal names with C identifiers to replace run time errors with compile time errors.
OpenC++ is a source code translation tool for C++. Programmers can easily implement various kinds of translation so that they can define new syntax, new annotation, and new object behavior. OpenC++ is useful if they need to, for example, develop extensions to C++, add domain-, application-, or class-specific compiler optimizations, or build their own version of (runtime) MOP for C++.
OpenJava allows programmers to customize the language to implement new language mechanism through MOP. OpenJava helps people who want to develop better Java libraries. It also helps people who are developing their own extended Java languages. OpenJava can also be regarded as a toolkit for constructing a Java preprocessor.
Cameleon a Framework for developing reliable database applications in a technology independent and predominantly editorial way. User interfaces may be easily exchanged from Swing to HTML and vice versa, and databases may be exchanged in the same manner. The Swing variant framework is established. The HTML user interface is under construction but can be reviewed on the project Webpage ("Test sample application"). Cameleon's target users are programmers who manage midrange data volumes (from thousands to millions of database records) and who prefer simplicity and availability rather than animation. Business features such as security management and parameter administration are supported in the framework. The framework allows web developement without any knowledge of JSP, HTML, Servlets etc. Data input elements (and groups of them) may be used in Java Server Pages.
The Quick C-- compiler is an experimental implementation of the C-- language. C-- is intended to be a "portable assembly language" that can be used as a target language by compiler writers. C-- features a simple C-like core and support for garbage collection and exception handling.
ClearParse is a flexible engine that can be used for any parsing task including interpreting or compiling programming languages, analyzing or converting data files, processing command line parameters and user input, implementing markup languages and scripts, natural language processing (NLP), and more.
