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).

The newest version!

/**
 * Contains parameters for state transfer. Exchanged between channel and STATE_TRANSFER
 * layer. The state is retrieved from 'target'. If target is null, then the state will be retrieved from the oldest
