Apache .NET Ant Library is a library of Apache Ant tasks that support development for the .NET platform. It supports Microsoft's frameworks as well as Mono. The library contains tasks to run common .NET development tools like NUnit, NAnt, or MSBuild. In addition, it contains a task to create Windows MSI installer packages using the WiX toolkit. The "old" .NET development tasks of Ant's core have found a new home here as well, and further development of those tasks will happen inside of this Ant Library.
Apache ActiveMQ is a popular and powerful message broker and enterprise integration patterns provider. Apache ActiveMQ is fast, supports many cross language clients and protocols, comes with easy-to-use enterprise integration patterns and many advanced features, while fully supporting JMS 1.1 and J2EE 1.4.
AntUnit is a library of Ant tasks that was initially developed to write tests for Ant tasks without resorting to JUnit. It makes it easy to turn an existing build file that exhibits an error into an AntUnit test. Tests are written as targets in a build file using assertion tasks provided by AntUnit. The antunit task executes targets in a collection of build files and supports custom listeners in a manner similar to the junit task's formatters.
Apache Cayenne is a persistence framework that provides object-relational mapping (ORM) and remoting services. It has a wealth of unique and powerful features and can address a wide range of persistence needs. Cayenne seamlessly binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. With native XML serialization, objects can be even further persisted to non-Java clients.
