It's not a giant leap, according to Benfield. The ThinkCAP JX Framework already integrates about twenty-five open source frameworks and engines, including Struts, Hibernate, JavaTidy, Jakarta, and, perhaps most relevant, prototype.js and script.aculo.us, the AJAX libraries used by Ruby on Rails, another popular open source development tool that is similar to ThinkCAP JX Framework.
"Ruby has some cool features but I'd categorize it as more of a 4GL vs. a RAD environment," says Benfield. ThinkCAP JX Framework adds visual controls, transaction support, and three-tier event models, without having to re-write code, he says, and reduces development times by 25%.
In addition to GPL licensing, ThinkCAP JX Framework is also available under a royalty-free commercial license for developers who want to distribute or sell binaries of modified versions of ThinkCAP but keep the code to themselves. That license costs $2,000 per developer.
