"Honestly, OpenXava has changed the way Rapid Application Development should be. We are happy developers since then."
"I have worked before on Low-Code platforms like Mendix, Pega, OutSystems, etc. It seems easier to work without code only drag and drop and set properties, but still it is easier to work with OpenXava."
"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."
"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."
"I have been looking for a logical, understandable, simple approach to web tools for years now and OpenXava is the first thing I have found that fits that bill. Most tools like VisualStudio Web App are so extremely confusing and so many moving part that the learning curve is insurmountable."
"Openxava is brilliant. I used Wavemaker as a UI before, and that was really hard work."
"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."
"Excellent framework. Easy implementation, pretty simple yet very powerful."
"Great for Rapid Development."
"I am using OpenXava and finding it wonderfully refreshing, as someone who needs to program in Java with no Java knowledge it is a wonderful tool so thanks!"
"This framework never ceases to surprise me, the best development framework you've never seen, without a doubt. Speechless."
"OpenXava is a high quality framework for Java. Very productive."

From Struts 2 MVC to OpenXava
Datta Enterprises is an Indian company owned by Bhosle Group with a legacy of more than 70 years and engaged in exports of packaging machines and high precision machine components to Europe and Japan. The apex goal of the company has always been Lean Manufacturing with comprehensive automated control over the business processes in its entirety with minimal human intervention. The ERP is more proactive than reactive, making the management prognosis problems and taking corrective measures before they occur rather than fire-fighting the incidents. The ERP has helped the company to engage minimal workforce, control costs, maintain transparency to the customers as well as the statutory compliance without affecting the product pricing. OpenXava helped develop the ERP with the team concentrating more on building business logic rather than engaging in technical programming details. Thanks to the Business Objects of OpenXava, the entire ERP was developed by just three people, a designer, a developer and a tester. The project went into production on the designated date.
When we asked Ajay Narke, principal developer for the project, why they moved from Struts 2 MVC to OpenXava, he says:
"I shifted from Struts 2 MVC framework to OpenXava as I found working with Business Objects of OpenXava accelerated the development to the fullest throttle."
