SAN FRANCISCO -- Sun Microsystems, Inc. (NASDAQ:SUNW) today announced the availability of a qualification release of the Java(TM) 2 Platform, Enterprise Edition (J2EE(TM)) version 1.4 source code for licensees of the J2EE platform. Available less than one month after the WS-I Basic Profile was finalized, the source code delivers support for the final WS-I Basic Profile and includes the J2EE programming model for portable Web services applications. The source-code release includes compatibility tests, allowing J2EE licensees to make progress on implementing J2EE 1.4. "With our partners and as a WS-I board member, Sun is leading the charge in supporting standards-compliant, Java Web Services platforms," said Jeff Jackson, vice president of Sun J2EE platform and application server engineering, Sun Microsystems, Inc. "Java and Web Services merge in J2EE 1.4 as the preferred platform for building enterprise-grade applications and the only available software environment that is platform independent and interoperable by design. The introduction of J2EE 1.4, with its support for more Web services standards and protocols than any other platform, is a prime example of Sun's leadership position in this space." WS-I specifications are designed to ensure interoperability between different vendors' Web services products. Through the Java Community Process (JCP), Java provides open application programming interfaces (APIs) to provide enterprises with a choice and to keep developers from becoming dependent upon a single vendor's technology. Java developers can save time and money by working with standard APIs for XML (Extensible Markup Language) and Web Services, such as JAXP, JAXB, JAX-RPC and JAX-R, instead of proprietary APIs that may change from vendor to vendor. Java and XML technologies allow users to easily develop applications that can be seamlessly deployed across all major operating platforms, including Solaris(TM), Linux and Windows. In addition, Java developers won't be tasked with learning specific Web services specifications or acquiring WS-I interoperability expertise, because profile guidelines are included in Java platforms and development toolkits such as the Java Web Services Developer Pack (Java WSDP). The Java platform also enables IT organizations to leverage their current technology investments by providing simplified integration with applications and legacy systems, reducing cost and complexity within the organization. As a board member of the WS-I organization, Sun is continuing 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). Java has long been the developer's choice for Web services, and J2EE 1.4 represents a culmination of work by the JCP and the technology industry to deliver the first platform to support the WS-I Basic Profile.
