Web services in J2EE 1.4

InfoWorld (U.S. online)
Oracle Corp. by the end of the year plans to release an upgrade of its JDeveloper tool for Java that backs the latest J2EE standard, which focuses on Web services.
JDeveloper 10g will support J2EE 1.4, the Web services-enabled variant of J2EE, as well as more visual development and modeling so developers do not have to write low-level coding in order to take advantage of J2EE and Web services, said John Magee, Oracle vice-president of application server and tools in the company’s product marketing group. Magee spoke during an interview at the recent OracleWorld conference in San Francisco.
While Oracle is emphasizing grid computing with the newly announced 10g versions of the company’s application server and database, the 10g version of JDeveloper is not specifically tuned for building grids, Magee said. But JDeveloper 10g will serve as Oracle’s development environment for building ser-vices-based applications for the grid, he said.
“Our approach for commercializing technology is we don’t think customers should have to get a toolkit for building a grid. We want to build that into our database and application ser-ver,” Magee said.
JDeveloper is Oracle’s high-end development tool for enterprise-level applications. The company with Oracle Database 10g plans to include a database application development tool called HTML DB, for building simpler applications, Magree said.
HTML DB, also known as Project Marvel, provides a way to build Web applications and run them from a central data repository, he said. Applications can be developed and deployed in the same environment.
“HTML DB is a very easy-to-use, Web-based development environment,” said Magee.
“You can build database applications as easily as people work with spreadsheets today,” he said.
Oracle Database 10g is expected out by the end of the year, according to Oracle’s Robert Shimp, vice-president of database pro-duct marketing.
A beta tester of version 10g of the database at Qualcomm Inc., in San Diego, said his company wants to utilize 10g to save time for database administrators.
“With 10g, all the manageability features are bundled into Oracle Enterprise Manager. That is sort of an intelligent tool that will find out all the performance issues in your system,” said Arvind Gidwani, Qualcomm IT manager. The company is pleased with 10g’s self-tuning and self-healing functions, he said.
Qualcomm is running a grid on two eight-processor Sun Microsystems Inc. servers using the Solaris operating system. The company has been running the grid for about a month and is happy with the performance, he said.
Oracle Database 10g features clusterware software for faster integration and management of software, Shimp said, so that users do not have to purchase clusterware from a separate company.
