POJava Persistence is a small library of tools used in the persistence and retrieval of data to and from storage, such as to a database or XML document. It contains an ORM (Object Relational Mapping) tool that supports use of existing beans and POJO's rather than requiring POJO's to be instrumented to support a tool.

The newest version!
