In previous versions of the connector for JMS, the data handler that was used to convert data between JMS messages and IBM CrossWorlds business objects was determined by the DataHandlerConfigMO and DataHandlerMimeType connector properties. This had the limiting effect of requiring multiple instances of the connector to process different data formats. In release 1.2.x, the connector now allows you to optionally specify these properties in the connector's static meta-object or in a request business object's dynamic child meta-object. For details, see Configuring meta-objects.
