BeanKeeper is a full featured, powerful object/relational persistence and query library. It has a unique philosophy of simpleness and ease of use: it does not require config files, annotations, code generation, code "enhancing", or any kind of tools to be used. It handles simple Java beans (or POJOs) and its query service returns lists. Despite its simpleness, under the hood the library takes care of all the necessary logic: transaction visibility, result list paging, keys and ids, table creation/modification, class relations, inheritance/polymorphism, case sensitiveness, and much more. It currently supports: Oracle, HSQLDB, MySQL, and PostgreSQL.
This project aims to be a complete, easy-to-use implementation of the Ogg protocol. It has a high level (standard Java stream) interface, which can be used with minimal knowledge of the Ogg internals. It can also be customized to use the full power of the Ogg stream format, such as custom Paging and multiplexing logic.
The Java Exorcist is a simple Java syntax extender. By default (with no extensions), it only compiles standard Java code, but with each extension to Exorcist a new Java language construct can be defined or redefined. The Exorcist preserves line numbering at runtime and at compile-time. It can be invoked on the command line and through an ant task.
