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

/**
 * A {@code ServerSessionPool} object is an object implemented by an application server to provide a pool of
 * {@code ServerSession} objects for processing the messages of a {@code ConnectionConsumer} (optional).
 *
 * 
 * Its only method is {@code getServerSession}. The Jakarta Messaging API does not architect how the pool is implemented. It could be
 * a static pool of {@code ServerSession} objects, or it could use a sophisticated algorithm to dynamically create
 * {@code ServerSession} objects as needed.
 *
 * 
 * If the {@code ServerSessionPool} is out of {@code ServerSession} objects, the {@code getServerSession} call may
 * block. If a {@code ConnectionConsumer} is blocked, it cannot deliver new messages until a {@code ServerSession} is
 * eventually returned.
