Examples of org.codehaus.activemq.message.ActiveMQObjectMessage

org.codehaus.activemq.message.ActiveMQObjectMessage
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. @see javax.jms.Session#createObjectMessage() @see javax.jms.Session#createObjectMessage(Serializable) @see javax.jms.BytesMessage @see javax.jms.MapMessage @see javax.jms.Message @see javax.jms.StreamMessage @see javax.jms.TextMessage
