Creating threads inside an application

[pref]

Since EJB discourages creating new threads inside business methods, what is the proper way to create new threads with WidlFly? There is a third-party library that accepts java.util.concurrent.Executor as a parameter. I saw examples of using jboss:domain:threads subsystem to create executors from JBoss module (Infinispan uses this approach). But how can I get access to this service from a non-module code (in a deployment)? Is it allowed to use org.jboss.as.server.CurrentServiceContainer to get a reference to ThreadPool from a deployment?

WildFly supports EE7 and you might use the Executor which is new in EE7.

See the Java tutorials for concurrency

Yes, the javax.enterprise.concurrent.ManagedExecutorService is the way to go in EE7. The complete JSR is https://www.jcp.org/en/jsr/detail?id=236.

Thanks for the hint. What is the proper way of doing it with JBoss 7?

As AS7 implement JavaEE6 there is no 'propper' way to create threads.

You might use Asynchronous EJB invocations or JMS.

Or you accept the drawback of creating threads, but that might end in leaks or you might not able to shutdown the server correct.
