What JDK do I need to write a server?

Question

Java

Always used only Java SE, but then a new task appeared, I need a server, and I'm a little confused about which
JDK I need, EE? SE?
Is SE included in EE?

Answer 1

jdk ee doesn't exist in nature, it's more of a technology stack. Just install maven, it will pull up what you need

Answer 2

EE. SE included. In addition, the reference application server is also included. But in general, as a rule, deployment goes under Jboss or just under a servlet container like tomcat or jetty. In this case, SE is enough, and additional dependencies through maven (gradle) will have to be pulled in both cases.
