Sun outlined a roadmap for its Enterprise Java Beans (EJB) specification at the Iona World user conference in San Francisco on Wednesday.
While version 1.0 was published in March last year, the second release, codenamed Moscone, is currently being reviewed by Sun?s partners and is due to go into public review in March or April. The final version should be available by June, while the company also plans to complete a reference implementation for technical review by the second or third quarter.
Mala Chandra, a Sun director, said: ?The focus on Moscone is to tighten up the 1.0 specification in terms of performance descriptors and using XML for data description. We?ve also tightened security.?
The offering includes support for Web technology, data access, transaction processing, messaging, publish and subscribe, and naming and directory services. It will come with compatibility tests to ensure interoperability and portability, and include design templates and documentation, which outlines how to build applications.
Version 3.0 of the EJB specification, codenamed Javits, however, will also include connectors to link EJBs to enterprise applications such as SAP, while version 4.0, codenamed Milance, will make entity beans mandatory. Javits is due in the first quarter of 2000, while Milance is expected by the fourth quarter.
Elsewhere, Sun also expects to put its Java Server Pages specification up for public review next quarter. Server Pages will provide users with guidelines for scripting server applications in Java and is intended to enable them to dynamically create and customise Web pages using only one language.
