A more efficient supply-chain management software by AEB


AEB's application framework makes it easy to create cloud-based B2B software for SMEs working in supply-chain management, logistics, and global trade.

Modernizing a UI-Rich App Framework

Switching the existing Java/Swing application framework with 1500+ existing UIs to an HTML5 based UI without the need of programming each of them all over again. Besides that, the requirement of a local JRE Installation did cause a lot of issues in service and support. Especially for products with a lot of customers. And what made it even harder, Oracle has started to tag Java Web Start due to security reasons as deprecated and will most likely remove support in Version 11. This technology was required to launch AEB applications on the client.

A relatively small development team of only 5 developers made it impossible to take care of every UI feature in every browser. In addition to that AEB had a lot of know-how in server-side Java programming but very little know-how of Javascript HTML5 client-side programming.

Desktop to Web Migration with Vaadin

AEB found that Vaadin was an HTML5 framework that has been on the market for some time and it fits very well with their way of server-side programming. After the first proof of concept in a small application, it became obvious that Vaadin was a suitable successor for the company’s existing UI framework.

An internal team consisting of a UI designer, a usability expert and 5 developers started migrating from Java Swing to a web application with Vaadin in 2015. The new Vaadin UI is currently used by all the customers of AEB who rely on the XNSG Java Framework in 20 different applications. The solution continues to be in production, as the last two apps that have a lot of users are migrating from Java Swing to web application with Vaadin UI. 

Following this, a workshop was held on-site by a Vaadin expert who demonstrated how Vaadin 10 works and what major changes come with the new technology. Migrations strategies were evaluated to discover the best approach, and a rough estimate was given on how long it would take AEB to migrate all client-side adaptations to new Vaadin 10 controls.

Early Adoption & New Use Cases

AEB’s numbers show that there are on average 100,000 logins per week in the data center. Almost 20% of these are already using the new Vaadin UI, suggesting that many customers in the company’s data center are already using the new UI on a daily basis.

The new state-of-the-art UI is not only fresh and dynamic but also highly appreciated by customers. Since Java JRE installation is no longer required, customers are happy about the saved operation costs that occur on their side, too, not only on AEB’s.

The Vaadin UI in HTML5 has enabled AEB to create mobile applications for Warehouse Management use cases that are already running on new Android scanner devices replacing older applications that required a complex infrastructure to work on older scanner devices.
