public interface: ObjectMessage [javadoc | source]

All Implemented Interfaces:

An ObjectMessage object is used to send a message that contains a serializable object in the Java programming language ("Java object"). It inherits from the Message interface and adds a body containing a single reference to an object. Only Serializable Java objects can be used.

If a collection of Java objects must be sent, one of the Collection classes provided since JDK 1.2 can be used.

When a client receives an ObjectMessage, it is in read-only mode. If a client attempts to write to the message at this point, a MessageNotWriteableException is thrown. If clearBody is called, the message can now be both read from and written to.

Method from javax.jms.ObjectMessage Summary:
getObject,   setObject
Method from javax.jms.ObjectMessage Detail:
 public Serializable getObject() throws JMSException
    Gets the serializable object containing this message's data. The default value is null.
 public  void setObject(Serializable object) throws JMSException
    Sets the serializable object containing this message's data. It is important to note that an ObjectMessage contains a snapshot of the object at the time setObject() is called; subsequent modifications of the object will have no effect on the ObjectMessage body.
