SNAP Platform is a development toolkit that packages into an easy to install solution the the Jikes Java compiler, the SableVM Java-like virtual machine and the GNU Classpath Java-like API, and the Eclipse universal tools platform, plus sample programs with source code and developer documentation.
x4juli is a port of the main parts of log4j to the J2SE Logging API. The default implementation is incomplete and therefore still not widely used, even when introduced in J2SE 1.4. x4juli provides logmanagers, formatters, handlers, and filters to fill the gap. The interface and use of the original API has not been changed. Additionally, x4juli delivers a native implementation of the Jakarta Commons Logging (JCL) API and the Simple Logging Facade for Java (SLF4J) API.
SharpTAL compiles XML-based templates to .NET assemblies. It contains a complete implementation of the Zope Page Templates (ZPT) language, a system which can generate HTML, XML, or plain text output. ZPT is formed by the Template Attribute Language (TAL), the Expression Syntax (TALES), and the Macro Expansion Template Attribute Language (METAL).
Wicket Web Beans (WWB) is an Apache Wicket component toolkit for displaying and editing POJOs that conform to the JavaBeans specification. Web pages are automatically generated based on bean properties and certain conventions. If necessary, the layout, editability, and actions of these pages can be customized on an exception basis. In other words, the toolkit normally does what you'd expect, but when it doesn't, you can override its behavior.
While the author of BSAX-J has not yet come to a final conclusion about the need for a binary XML format, BSAX is his idea of one possible encoding that leverages other XML prior art (SAX events and UTF-8, in particular). It is complete in that it can be used to perform round-trip conversions from textual XML to SAX events to BSAX binary streams, and back to SAX events and textual XML. The test code in the distribution does exactly that for a simple example XML file, and measures the difference in file size (the file is slightly smaller for the BSAX encoding of the sample file) and the difference in read time (the read time is significantly faster for the sample file).
WSO2 WSF/Spring provides an amazingly simple "Code First" approach to create Web services for the Spring user. This framework integrates the Apache Axis2 Web services engine into Spring. Thus, it provides all the power and versatility of the Axis2 engine to the Spring user. With just a few entries in the application context, this lets Spring users enjoy the benefits of Service Oriented Architecture using Web services in their applications.
JewelCLI provides an API to parse command line arguments. It uses Java annotations to present a very simple but powerful interface. Options are defined using an annotated Java interface definition. This allow a declarative style which can be much clearer than the procedural style used by some other Java CLI libraries.
