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).

There is a newer version: 34.0.0.Final

/**
 * Designates a JavaBean as an ActivationSpec. This annotation may
 * be placed on a JavaBean. A JavaBean annotated with the Activation annotation
 * is not required to implement the {@link ActivationSpec ActivationSpec}
 * interface.
 * 
 * The ActivationSpec JavaBean contains the configuration information pertaining
 * to inbound connectivity from an EIS instance. A resource adapter capable of
 * message delivery to message endpoints must provide an JavaBean class
 * implementing the {@link ActivationSpec ActivationSpec} interface or annotate
 * a JavaBean with the Activation annotation for each supported
 * endpoint message listener type.
 * 
 * 
The ActivationSpec JavaBean has a set of configurable properties specific to
 * the messaging style and the message provider.
 * 
 * Together with the messageListener annotation element, this annotation
 * specifies information about a specific message listener type supported by the
 * messaging resource adapter.
 * 
 * @since 1.6
