jakarta.ejb.Asynchronous Maven / Gradle / Ivy
Go to download
This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).

* Used to mark a session bean method as an asynchronous method or to designate all business methods of a session bean
* class as asynchronous.
*
* An asychronous method must have return type void or Future<V>, where
* V is the result value type.
*
* Asynchronous method invocation semantics only apply to the no-interface, local business, and remote business client
* views. Methods exposed through the enterprise bean 2.x local, enterprise bean 2.x remote, and web service client
* views must not be designated as asynchronous.
