Future Enhancements
Several areas are targeted for improvement in the next major release of the J2EE specification. Support for “web services” is expected to be a larger part of the J2EE specification in the future, including support for Java API for XML Messaging ( JAXM), Java API for XML Registries ( JAXR), and Java API for XML RPC ( JAX-RPC). Support for the XML Data Binding API, which considered easier to use than JAXP, may also be required in a future version of the specification.
In addition, J2EE may be expanded to require support for JDBC rowsets, SQLJ, management and deployment APIs, and possibly a J2EE SPI that would build on the advancements made with the JCA specification.
