The best Java frameworks of 2020

We invite you to have a look at this article published at hackr.io:

10 Best Java Frameworks to Use in 2020

This is a very interesting article, especially if you don't come from the Java world, because it explains what Java frameworks are and why they are so important.

We're proud to be part of the list and we like to see the explanations about OpenXava from a third-party. We love it if you read the part of OpenXava and give us your opinion.

Coruña Harbor Market with OpenXava

S2 Informática has computerized the A Coruña Harbor Market (Spain) using JavaFX, JasperReports, Microsoft SQL Server and OpenXava. JavaFX applications are used by touch screens from which they do the weighing of the ships, the sale of ice and the collection of empty boxes. These applications share the database with the OpenXava application and when they weigh, sell ice, collect boxes on touch computers, users in the office can view in real time the data in the OpenXava web application, and can even add records to master files such as Ships, Species, Customers, etc.

When we asked Alberto Pallas from S2 Informática about OpenXava he said:

"It works very well and since version 6, the user interface has improved a lot, the user permissions are super cool and the performance is very good."

ZX-Ed: Open source database editor

ZX-Ed is a database editor and script generator for ZXDB. ZXDB is an open database containing historical information of software, hardware, magazines and books about ZX-Spectrum and related machines. It's currently the most widely used Sinclair related database, feeding several Spectrum websites, an open API at ZXInfo, and the mobile application Zx App that uses this API. It's also used as index reference by a dozen different websites and services. ZX-Ed is open source and available on GitHub. It was created by Einar Saukas using OpenXava.

When we asked Einar why he chose OpenXava he tells us:

"I needed a CRUD for an already existing, fairly complex database. However most existing tools and frameworks impose severe restrictions on the database structure they can handle, so they are not much viable in practice. After comparing several CRUD design solutions, I believe that OpenXava provides the best tradeoff between flexibility and productivity. You only need to generate and maintain entity code (that can match any database model), and everything else is optional (OpenXava provides an appropriate default behavior for everything else)."
