OSS/J delivers standards-based interface implementations (OSS/J APIs) and design guidelines for the development of component-based OSS systems.

OSS/J technologies provide the foundation for unifying legacy systems and new applications quickly and at low cost. The OSS/J APIs support multiple technologies and include Java, XML, and Web Services integration profiles.

Each integration profile consists of specifications, a reference implementation, and a conformance test kit (CTK).

All OSS/J APIs are publicly available at no charge.
