Oracle talks open source unto Java

All for one

The essential guide to IT transformation

JavaOne Oracle has played up its open source credentials with technologies to simplify Java development. It is also making ommunity donations to advance its middleware and tools for online services.

The database giant today announced a set of 80-plus AJAX components that provide data binding between Java and things like IM, email, voice and video data on sundry fixed and mobile devices.

As well as extending the software industry's JSF interface technology, Oracle's AJAX components also feed into Oracle's JDeveloper IDE and Application Development Framework (ADF).

Oracle has donated the Java Server faces (JSF) 1.2 components to the Apache Software Foundation (ASF) under the group's Rich Client Framework (RCF) sub project.

Also announced is an Oracle Development Kit or the Spring Framework, to simplify the development and deployment of applications using Spring on Oracle's Java tools and middleware. Oracle's transactional tools, interface manager and development tools have been integrated with Spring 2.0. The Spring Development Kit features wizards and full editor support for Spring in JDeveloper, pre-packaged sample applications and tutorials

Components of the kit will be donated to the Spring community, following on from last year’s donation of Oracle’s TopLink Essentials Java object to relational persistence mapping software.

Thomas Kurian, senior vice president of Oracle server technologies development, told JavaOne delegates: "We are contributing technology to create new opportunities for the Java community."

The move will also benefit Oracle's own Java business directly: according to Kurian, the Oracle Technology Network (OTN), which provides tools, code and resources for developers, now has five million members.

According to Kurian, the components let developers write AJAX in the browser without need for a plug in and also support Adobe Systems' Flash player to display dynamic data. The next version of JDeveloper and ADF will feature an enhanced ADF Render Kit that adds support for Flash rendering of data visualzed components like charges, along with Scalable Vector Graphics, and include a JavaScript editor and debugger.

"You hear a lot about AJAX – it's about bringing interactivity into applications that are in the browser. Traditional AJAX has required the developer to program in JavaScript – many people find that complex," Kurian said.

Previews of JDeveloper and Oracle ADF, in addition to the Java Enterprise Edition 5.0 version of Oracle’s application server – certified and previewed today – are available for free download from OTN. Kurian did not provide date for release of the trio. ®
