Sun Microsystems has announced the latest version of its Java 2 Enterprise Edition (J2EE), which it claims will simplify business integration and make it easier to use Java in building enterprise-level web applications and services.
Bringing Java's write-once run-anywhere promise to the server has been the underlying goal for J2EE for about the past 20 months. J2EE 1.3 is the first full release to come out of Sun's Java Community Process.
Included in the latest release are J2EE connectors that enable integration between Java web applications and legacy systems. They include connectors from SeeBeyond Technology, which provides linking software to IBM's CICS, PeopleSoft, SAP's R/3 and Oracle.
Another feature included in the release is the Java Message Service that allows an application to create, send, receive and read messages without requiring the sender or receiver to be available at the same time.
Rich Green, vice president and general manager, Java and XML Software at Sun, said in a statement: "This latest version of J2EE enables companies to integrate their legacy systems with evolving standards, allowing them to deploy a competitive architecture for web services."
Sun said its Enterprise JavaBeans 2.0 simplifies the development of distributed applications by giving the container of an Enterprise JavaBean the ability to write data so that it can be saved in memory and used again with the Enterprise JavaBeans.
The company also said that it has increased XML integration with the Java API for XML Processing and added the ability to write and manipulate JavaServer Pages technology in XML.
In a research report from Giga Information Group, analyst Randy Heffner said the J2EE platform provides a richer set of tools and more vendor independence than Microsoft's .Net.
He believes that, over the next two years, Microsoft will not capture more than 35 per cent of the enterprise development market and will make little headway against Sun's J2EE, its major competitor.
