Alma is a software workshop for modeling and analyzing. It reads several sources (languages, models, etc.), helps you design for object-oriented modeling (definition of classes, relations, patterns, etc.), modifies the structure and the code, and outputs new sources, documentation, diagrams, etc. It is designed for object-oriented modeling (definition of classes and relations) and for migrating code in older languages. It meets two needs, offering a simplified software modeling workshop for small projects and making it easier to do rewrites, ports, and encapsulation of non-OO code.
Apache Jakarta Regexp is a 100% pure Java regular expression package. Expression syntax supports all of Perl5 syntax, with the exception of back reference substitution markers (several people have mentioned this lack, so please feel free to contribute a solution). It also supports a very limited subset of POSIX features. Performance and features are somewhat inferior to ORO, and the new JDK 1.4 (java.util.regex) package, but the package is especially small and features the ability to precompile expressions (without using object serialization) into byte arrays, thus avoiding the need to load the expression compiler.
Arabeske is a special kind of vector drawing software. It has a limited set of shapes but is extremely specialised towards complex symmetric interlaced drawings, like those traditionally found in Arabic architecture. It is not a texture editor, but rather a pattern generator. It exports in EPS, PNG, and POV-Ray formats.
Avalon is Apache's Java Server Framework project. It is separated into six subprojects: Framework, Excalibur, LogKit, Cornerstone, Phoenix, and Apps. Its purpose is to simplify server side programming for Java-based projects. It formalizes several best practices and patterns for server side programming. Framework describes the interfaces and contracts for the component-based architecture. Excalibur provides a number of useful components and utilities. LogKit is a logging implementation. Cornerstone is a group of reusable server components and services. Phoenix is an enterprise container implementation that uses all of the other subprojects to automatically deploy and manage one or more componentized servers. Apps is a home for several Phoenix-compatible server applications and reusable components (like FtpServer).
Babelj is a language server for Java. It allows programs written in practically any language to fully interact with Java. Client libraries currently exist for PHP3 and Java. Babelj can be used as an out of the box bridge between PHP and Java and adding support for new languages is a snap as well.
Babylon Java Chat is a client and server combo that allows groups to chat and draw over any TCP/IP connection. The client can be run either as a standalone Java application or as an applet launched from a WWW document. It features public and private chatting and drawing, email, file transfers, chat rooms, instant and answering-machine style messaging, and console paging. The drawing canvas enables users to draw freehand, or to create lines, rectangles, ovals, or fonted text, or to paste images from files.
