JMS formats
To write code that can access the different JMS message types, know how each message type is mapped to SDO, and how to retrieve the message format string from the message.
Format types
Each JMS message type is defined by a message format string within the message. We can retrieve the format string by using the code snippet in the example below. The following table shows the mapping of message format strings to Service Data Objects (SDO):
JMS Message type Message format string Map to SDO1 JMS Bytes message JMS:bytes See JMS Formats - bytes JMS Text message JMS:text See JMS Formats - text JMS Stream message JMS:stream See JMS formats - Stream JMS Object message JMS:object See JMS Formats - object JMS Map message JMS:map The retrieval or construction of SDO data graphs for JMS map messages is not supported. 1 The version of SDO supported by mediations is v1.
Example
This code snippet is an example of how to retrieve the message format string from the message:
String format = siMsg.getFormat(); if (format.equals ....
