Sun Microsystems today announced the latest version of the Java 2 Platform, Enterprise Edition (J2EE) that is claims will simplify business integration across multiple systems and applications.
Some of the new features of J2EE 1.3 include increased XML integration and Java Message Service (JMS) application program interface (API) and Message Driven Beans. This allows Java API applications to create, send, receive and read messages without requiring both the sender and receiver to be available online at the same time.
Sun also standardized the interfaces between J2EE application servers and back-end applications by requiring J2EE licensees to include standard connectors to enable easy integration with existing systems and Enterprise Resource Planning (ERP) and Customer Resource Management (CRM) applications.
Enterprise JavaBeans 2.0 (EJB) improves interoperability and communication between application servers from different vendors with Internet Inter-ORB Protocol (IIOP). It does this by incorporating standard protocols within J2EE 1.3.
Some developers already building on new Java applications on J2EE 1.3 include BEA, Borland, Computer Associates, iPlanet, Oracle and Sybase.
Borland Singapore’s Michael King, feels that J2EE 1.3 will provide performance gains for web deployment. The repackaging to include the HotSpot Client VM helps to boost improvements in terms of startup time and a smaller RAM footprint, he said.
According to Lee Chuk Munn, senior developer consultant at Sun Microsystems in Singapore, existing Software Development Kits (SDKs) will not be affected by J2EE 1.3. According to him, J2EE 1.2 applications will run in J2EE 1.3.
“However, if you want to take advantage of the new features included, you would need to modify your code.”
“Otherwise, your existing J2EE 1.2 applications would run unmodified,” Lee said.
J2EE 1.3 is available for a free download now at Sun’s Java web site.
