BANGALORE: Sun Microsystems has released a ‘qualification’ version of the source code for Java 2 Enterprise Edition 1.4 for licensees of the J2EE platform. The source code provides support for the final WS-I Basic Profile and includes the J2EE programming model for portable web services applications. The release includes compatibility tests, allowing J2EE licensees to make progress on implementing J2EE 1.4 in their daily work.

Key new features in the J2EE 1.4 pre-release build include additional support for JSP pages, more efficient interoperability with existing J2EE connectors and improved support for management and tool vendors. This code is expected to be a prerelease build, so that developers can start with testing processes.

The new J2EE 1.4 specification originally was to be released last February, but Sun delayed it twice in order to be able to include new Web service specifications from the Web Services Interoperability Organization (WS-I). WS-I specifications are designed to ensure interoperability between various vendors' Web services products. The WS-I has approved its new specs this August.

As a board member of the WS-I organization, Sun says that they will attempt to make key technological contributions to enhance the interoperability of Web services. To date, Sun has released several versions of its J2EE platform based on early WS-I specifications, such as Java Web Services Developer Pack 1.2 and J2EE 1.4 SDK Beta 2. Once J2EE 1.4 is finalized, Sun will release compatibility tests, source code and a software development toolkit (SDK).
