I have been doing this for a while, mostly for my new work (back to dev). My goal is being able to debug a Java web application, just like what I did for my previous work (Spring STS + Tomcat). The new work requires Eclipse + JBoss (some coworkers uses the not free Intelli-J).
Download / install Eclipse
link here, need to unzip, and install the Eclipse for JEE
Add a new server
I picked Wirefly 11. Read this post regarding JBoss EAP vs Wirefly. This has been helpful.
After that I was able to import a “maven project” (that runs on STS with vFabric server), and start the app in debugging mode. This seems like baby steps, but for me it’s a long time “not doing” 🙂
