Extended Virtual Synchrony for Java is a pure Java implementation of the totem single-ring protocol, which provides process group membership and reliable multicast with totally ordered messages. Because of its token-based design, this protocol is unique in achieving effective flow control, and is ideal for implementing replication in small clusters.
Graffito is a framework used to build content-based applications like CMSs, document management systems, forums, blogs, etc. It offers a complete platform for creating, managing, and publishing content in your portal or in any other kind of Java application. It integrates content repositories, workflow, collaboration, and personalization via existing open source projects and standards like WEBDAV.
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.
Jetspeed-2 is a full implementation of the Java Portlet API. It is fully compliant with the Portlet Specification 1.0 (JSR-168). It has passed the TCK (Test Compatibility Kit) suite and is fully CERTIFIED to the Java Portlet Standard. Notable features include security components backed by LDAP and database implementations, and some robust administration interfaces. Custom portals can be built and deployed using the Jetspeed plugin for Maven. Developers can use the Jetspeed PSML language to assemble portlets, and the Apache Portals Bridges project to 'bridge' portals with existing technologies including Struts, JSF, PHP, and Perl. For GUI designers, Jetspeed comes with several built-in templates used to decorate portals and portlets.
Nexenta is a complete GNU-based operating system built on top of the OpenSolaris kernel and runtime. The Debian system is used for software distribution and packaging to glue the numerous pieces together. However, Nexenta is not currently part of the Debian Project, nor are its packages present in the Debian database. It includes Apache, MySQL, Perl, Python, PHP, Firefox, Evolution, a software update manager, Synaptic package manager, Gaim, Abiword, administration and development utilities, editors, graphics, GNOME, interpreters, libraries, and much more.
Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
Puppet lets you centrally manage every important aspect of your system using a cross-platform specification language that manages all the separate elements normally aggregated in different files, including users, cron jobs, and hosts, along with obviously discrete elements like packages, services, and files. Its simple declarative specification language provides powerful classing abilities for drawing out the similarities between hosts while allowing them to be as specific as necessary, and it handles dependency and prerequisite relationships between objects clearly and explicitly.
codavaj is Javadoc in reverse: a seemingly useless reverse engineering tool to transform HTML Javadoc into Java source file skeletons (or a reflection API) like internal representation. You can: convert an entire local Javadoc tree into Java source code; download an entire remote Javadoc tree via HTTP(S); and derive a Reflection-like API based on information derived from a Javadoc tree. It is provided as a Java command line tool.
