About JMS Message Types

JMS defines five types of messages: TextMessage, BytesMessage, ObjectMessage, MapMessage, and StreamMessage. The Siebel JMS Transport supports only the types TextMessage and BytesMessage. If the JMS Transport receives an ObjectMessage, MapMessage, or StreamMessage from the JMS server, then the error Unsupported Message Type is produced.

Like all Siebel business services, the output of any method is a property set. If a BytesMessage is received, then the value of the property set has Binary type. If a TextMessage is received, then the value has String type.

Conversely, the input to any method is also a property set. For methods that involve sending or publishing a message, the type of message sent or published depends on the type of the value of the input property set. If the type is Binary, then a BytesMessage is sent and published. If the type is String, then a TextMessage is sent and published.

NOTE:  The Siebel Business Service Simulator in Siebel Call Center always creates the input with a value type of String.
