An ObjectMessage is used to send a message that contains a serializable Java object. It inherits from Message and adds a body containing a single Java reference. Only Serializable Java objects can be used.

Methods

getObject

public java.io.Serializable getObject()
                             throws JMSException

Get the serializable object containing this message's data. The default value is null.

Returns:

the serializable object containing this message's data.

Throws:

• JMSException - if JMS fails to get the object because of an internal JMS error.
• MessageFormatException - if object deserialization fails.

setObject

public void setObject(java.io.Serializable object)
                                      throws JMSException

Set the serializable object containing this message's data. The ObjectMessage contains a snapshot of the object at the time setObject() is called. Subsequent modifications of the object have no effect on the ObjectMessage body.

Parameters:

object - the message's data.

Throws:

• JMSException - if JMS fails to set the object because of an internal JMS error.
• MessageFormatException - if object serialization fails.
• MessageNotWriteableException - if the message is in read-only mode.
