Sun has just made available a free JavaTM 2 Platform, Enterprise Edition (J2EETM) 1.4 Application Verification Kit that tests for portability and the correct use of J2EE APIs across J2EE technology-compatible application servers. The tool lets users know that their solutions remain portable across the multi-vendor J2EE technology-based application server environment.

"One way in which developers seek to optimize resources is effective utilization of their existing infrastructure investment," said Joe Keller, vice president, marketing for Java Web Services and Tools, Sun. "The J2EE 1.4 AVK enables developers to do just that, providing for easier application migration from one application server to another, increasing code reusability, eliminating the need to install and test across multiple application servers and making multiple vendor environments not just feasible, but efficient. Sun is proud to be the only company to deliver a product that offers these very practical, very effective results."

If users employ value-add proprietary extensions that are not available across the range of J2EE-compatible products, the testing kit helps them avoid dependence on proprietary APIs and/or non-standard J2EE APIs that reduce application portability.

The test kit provides the following functionality:

• Web Services testing such as static checking for Web Services endpoints and dynamic checking for both Enterprise JavaBeansTM (EJBTM) architecture and Servlet-based Web Services

• Source code scanning for incompatible proprietary APIs that would cause interoperability challenges

• Incorporation of ANT (an open source program from the Apache Software Foundation for efficiently assembling all the pieces of a program) tasks in the development cycle

• Mapping assertions tested to the specification, enabling easy lookup

• Component libraries

A growing number of J2EE 1.4 licensees, including BEA, Borland, IBM, JBoss, Oracle, Pramati and Trifork, are displaying increasing interest in the J2EE 1.4 ecosystem. [...read more...]
