OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference, and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Bazaar, Git, ClearCase, Perforce, SCCS, RCS, CVS, or Subversion. In other words, it lets you grok (profoundly understand) the source.
The Java Engine for Testing (JET) is a system for running distributed automated tests. It has been used by Sun for testing the High Availability DataBase (HADB), JavaDB, PostgreSQL, Memcached, and the MySQL Cluster Manager. JET should be a good way to write your tests if the product you want to test is distributed or has a client/server architecture, if it is natural for you to write the tests in Java, and if you want to invest time in developing tests and abstractions for later reuse.
OpenDJ is an LDAPv3 compliant directory server written for the Java platform. Fully featured, it provides a high performance, highly available, and secure store for the identities managed by enterprises. OpenDJ is a continuation of the OpenDS project initiated by Sun Microsystems.
Restlet is a REST framework for Java. It supports all REST concepts (Resource, Representation, Connector, Component, etc.) and is suitable for both client and server Web applications. It supports major Web standards like HTTP, SMTP, XML, JSON, WADL, and Atom. Many extensions are also available to integrate with Servlet, Spring, Jetty, Grizzly, Simple, JAXB, JAX-RS, JiBX, Velocity, or FreeMarker. A GWT version is also available.
RIFE offers an alternative approach to web application development and design. It builds upon the Java platform, but offers all required tools and APIs to implement and perform all common Web site related tasks in a fast, intuitive, and consistent manner. RIFE is composed out of a large collection of modular parts, including a Web application engine, integrated Web continuations, a customizable multi-format template engine, support for template content transformation, and more.
Rachota is a small application for those who work with computers on a daily basis and are curious how efficiently they use their time. It is basically a scheduler that measures how much time one spends on pre-defined tasks during the day. The data can be used later for evaluation or generation of reports, e.g. for managers.
The Open Web SSO project (OpenSSO) provides core identity services to simplify the implementation of transparent single sign-on (SSO) as a security component in a network infrastructure. OpenSSO provides the foundation for integrating diverse Web applications that might typically operate against a disparate set of identity repositories and are hosted on a variety of platforms such as Web and application servers. This project is based on the code base of Sun Java System Access Manager.
