JAM (JavaGen Ant Modules) allows Java/J2EE developers to create robust, test-driven build environments with just a few lines of Ant script. Builds are simplified with a standard set of commands that you customize for your project. The Maven-to-Ant bridge manages classpaths, dependencies, versioning, and resource downloads automatically. JAM modules support JBoss, Tomcat 5, Resin, Oracle OC4J, JUnit, Cactus, XDoclet, CVS, Axis, Castor, JMX EJBs, and Hibernate.
EJOE is a lightweight Java remoting framework built to send and receive objects through pluggable (de)serialization mechanisms. It offers a high-performance, simple, and clean object request broker (whereby ORB is meant in its natural manner and not in its relation with CORBA), with server and client components for your client/server applications. It's a highly scalable implementation of the common request-process-response pattern based on Java NIO. It does support optional remote class loading to avoid redundant classpath entries, but doesn't require stubs and/or proxy objects.
GvTags is a lightweight yet powerful tag library and template engine for the dynamic programming language Groovy. The tag library can be used to generate Web pages with powerful tag support. It can be used with the template servlet of GvTags (TagTemplateServlet) or with JavaServer Pages (JSP). The template engine can be used to generate any kind of text documents. Since it is written in Groovy and compiled to a Java class file, it can be used from Groovy as well as from Java.
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.
weta-dfs is a distributed file system. It is designed to be fail-safe through replications of files, fast and easy to install, platform independent, and to have fast recovery from crashes. It consists of Data Node Servers and one Meta Data Server and a java.io.File-like client API.
