Typically, Apache's technologies can be leveraged in commercial offerings. "Companies take our technology and use them in commercial products and commit people to develop the code," said Jim Jagielski, executive vice president of the Apache Software Foundation and CTO of Covalent Technologies. "It's a nice, mutually beneficial relationship."

Version 2.0 of the popular Struts framework was unveiled, featuring easier testing and control. "The actual controller of the Struts framework is much more easy to customize," Jagielski said.

Struts also now will be easier to use in conjunction with another popular framework: Spring. "Basically, now they just plug right in together," Jagielski said.

With Version 2.0, Apache renews development of Struts. "It kind of stagnated for a while," said Jagielski.

The release of Jackrabbit Version 1.1 provides a conforming implementation of the Content Repository for Java Technology API. Applications using content repositories typically include systems for content, document and records management. The 1.1 release is an incremental release fixing a number of issues and introducing new features. The most notable change, according to Apache, was the removal of the Apache Xerces dependency and an improved item state cache. Xerces is an XML parser project at Apache.
