Can anyone please give me the main difference between JBoss AS 7 and WildFly 8?
I'm going to start a very important project and I have to choose between JBoss AS 7 and WildFly 8 (for this project I'm going to use GWT, JPA/Hibernate and jBPM 6).
WildFly, formally known as JBoss AS, is a completely open source community project that is free for development and production level deployments.
JBoss EAP is just a commercial build of the Wildfly project. In many ways, especially from a source code perspective, JBoss and Wildfly are the same thing. “Wildfly is the upstream project JBoss EAP is built on,” said James Falkner, technical product manager for Red Hat Runtimes.
JBoss EAP is the name for the Java EE application server that Red Hat produces and supports. The latest version is 6 at the moment and this implements Java EE 6. JBoss AS/WildFly is the name for the community project that you can test. This community project will eventually become JBoss EAP.
That being said, which is the recommended JDK version for WildFly ? There are two main options: WildFly versions up to 26 should run on the most recent long-term support release (LTS), i.e. on Java 8 and 11. On a balance, due to the amount of tests, it is recommended to use JDK 11.
WildFly 8 is the next iteration of the JBoss application server after JBoss AS 7 / EAP 6.
Basically:
Red Hat typically backports security fixes from newer versions into older versions, Red Hat also typically releases "feature packs" that allow you to access newer features/specs.
So if it is a very important project and you do not need JEE7 specs, you may want to use JBoss EAP which is the productized version of JBoss AS 7.
Otherwise you may want to use WildFly if you need the more cutting edge specs and features.
See JBoss AS / WildFly versions history for more details.
