5 Pillars of a Successful Java Web Application (Part 1/3)

There are many challenges related to building and architecting a web application, especially if you want to keep your codebase updated with modern techniques without throwing away a lot of your code every two years in favor of the latest trendy JS framework.

In our team, we can successfully keep a 7+ year-old Java application up-to-date, combining modern techniques with a legacy codebase of more than 1 million LOC, with an agile, sustainable, and evolutionary web approach.

More than just choosing and applying any web framework as the foundation of our web application, we based our web application architecture on 5 architectural pillars that proved crucial for our platform’s success. This post is a first in a series, that will discuss exactly that.

In the first week of October, Alex Porcelli and I had the opportunity to present at JavaOne San Francisco 2017, the two sessions we held related to our work: 5 Pillars of a Successful Java Web Application and The Hidden Secret of Java Open Source Projects.

It was great to share our cumulative experience over the years building the workbench and the web tooling for the Drools and jBPM platform and both sessions had great attendance (250+ people in the room).

In this series of posts, we’ll detail our “5 Pillars of a Successful Java Web Application”, trying to give you an overview of our research and a taste of participating in a great event like Java One. Let’s talk about them:

Upgrading to Vaadin Framework 8 (Part 2 of 2)

In the previous part of this blog, I talked about the most important steps to get your project to compile with the latest Framework version.

The migration has been done through the first three steps mentioned here, and in this post, I will go over the least complicated steps of migration. Steps 4 and 5 cover the modernization of your project with the latest Framework 8 features. If you are in a hurry, you can do this later on as well, and use the new APIs only for new Vaadin code.

  4. Upgrade non-data components
  5. Upgrade data components
  6. Back to the future

The Evolution of Technology in the Context of Software Development & Design Process: Take-away from PatternFly Conference

Last Sunday, I returned home, India, after attending a series of collaborative sessions in Raleigh, NC, with many designers and developers across Red Hat and the open-source community, at the UX Summit and the PatternFly Conference. The whole experience was inspiring, informative and at the same time thought provoking with many takeaways, out of which the most interesting for me was that cumulatively all the inspiring talks from the speakers of the conference were implicitly hinting towards a clue. How our attempt to solve the existing technical solutions also impact the existing work process and thereby demand a rethink on the process blocks we use.
