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

/**
 * An {@code ObjectMessage} object is used to send a message that contains a serializable object in the Java programming
 * language ("Java object"). It inherits from the {@code Message} interface and adds a body containing a single
 * reference to an object. Only {@code Serializable} Java objects can be used.
 *
 * 
 * If a collection of Java objects must be sent, one of the {@code Collection} classes provided since JDK 1.2 can be
 * used.
 *
 * 
 * When a client receives an {@code ObjectMessage}, it is in read-only mode. If a client attempts to write to the
 * message at this point, a {@code MessageNotWriteableException} is thrown. If {@code clearBody} is called, the message
 * can now be both read from and written to.
