Jakarta EE Survey 2020

At OmniFaces we poll the community from time to time about Java EE (now Jakarta EE) and related technologies. With the transfer of Java EE to Jakarta EE now almost completed, people are now starting to think about Jakarta EE 10 , the first Jakarta EE release after Java EE 8 having new featues.

When a GET request like localh
