BitNami JasperServer Stack is an easy-to-use installer for JasperServer, which is part of the JasperSoft business intelligence suite, built by the developers of JasperReports. It provides a Web and Web services based environment for reporting, data analysis (OLAP), and data integration.
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.
SlimWeb aims to replace Struts or JSF in your J2EE application, but is closer to Rails or TurboGears in its heavy use of convention-over-configuration, simplicity, and power. It aims to reduce (and most of the time completely eliminate) all boilerplate code, XML configuration files, and even deployment times.
visural-wicket is a useful set of light-weight, loosely coupled components and utilities for the Apache Wicket Web framework. Each component is designed to be easily integrated into any existing Wicket application with minimal dependencies. Each component is also designed to be easily customized to fit a particular system's requirements. Other than components, visural-wicket includes some other utilities that assist in the development of Wicket applications, such as an annotation-based mounting system, model templates, and an automatic "form view mode" component.
eXtcos is an extensible JVM component scanner, similar to the component scanning feature of Spring. It is a small library solely focused on the task of class path scanning. It provides an easy-to-use query language for requesting the classes. This is a refreshing change to the boiler plate code you need to use the Spring classes for your own needs. You can get several different kinds of classes with just one query. You can use eXtcos for finding plug-ins for your application, classes meant to be run inside your container or framework, and the like. eXtcos is basically a base library on which other applications, containers, and frameworks can depend on.
