OpenXava allows you to create powerful applications to visualize your business data, like FlexMonster, but OpenXava generates complete applications and it's open source.
In OpenXava you only have to write the domain classes in plain Java to get a web application ready for production.
"I can't recall when I was so excited about a framework, specially for web development. I have been in the field since 1983 and I am hard to impress. With OpenXava I am impress!"
"This is like a dream come true, as I have been wanting something like that since the day I programmed my first user interface"
"I must say: my compliments! ... I have actually quite a lot of experience in UI automation. So it takes a lot to impress me. And I am impressed"
"Honestly, OpenXava has changed the way rapid Application Development should be. We are happy developers since then"
"I've been able to put together more functionality in my initial 6 days of starting to learn OpenXava (and I know nothing about java itself - yet) than I was able to accomplish in several weeks of either RoR or Laravel, and I know a bit of Ruby and PHP."
"The real catch about our experience while developing with OpenXava was the speed of development without compromising the quality"
"OpenXava for me is an exceptional tool, saving us time, made it standard interfaces, imposed a criterion of unique development in the organization"
"Good tools with good support -- developer utopia!"
"I'm very excited. I have many flight hours as programmer and I didn't find something so good for a long time."
"I think OpenXava is an extraordinary tool, it makes reality a fantasy, that is MDD and at the same time works like a RAD, all this using Java."
Andrés Carranza Moreno
