From javax to jakarta, the path paved with pitfalls

Track: Jakarta EE

Abstract

The switch from javax to jakarta namespace is probably the biggest change in the Java ecosystem over the last 20 years. It does not only impact Java EE application servers, but all libraries, from Spring or Quarkus to TomEE. This presentation is about presenting the problem of migrating from javax to jakarta namespace. The pitfalls and challenges encountered based on a simple application example. We will go through the possible options and how best companies can switch. Now that we are in Jakarta, the platform is evolving very quickly and ignoring the challenge isn’t a good bet.
