How I Successfully Integrated a Java 1.6 Legacy EJB System into a Java 17 Spring Boot App!

Ever wondered how to modernize a legacy system without rewriting everything from scratch? Recently, I faced a challenge where I had to integrate a Java 1.6 EJB-based system into a Spring Boot application using Java 17. The legacy system had over 10 XML-based bean configurations, and I couldn't modify the legacy code!

After some trial and error, I found a solution that not only worked but also helped keep both systems in sync. Here’s how I did it: Loaded legacy EJB beans into the Spring Boot context via multiple XML files. Resolved common errors like NoClassDefFoundError by using the right dependencies (xercesImpl, xml-apis).

Leveraged Spring's Application Context to access the legacy beans and interact with them seamlessly.

Curious how this was done? 👇
