Sorry, we don't provide facilities for the integration of any specific back-end system to the Data Adapter interface, though we are working on doing something for the future.

If JMS is available in your J2EE environment to request data to your back-end, then coding a java Data Adapter which accesses JMS would be an advisable approach.
Note that we provide a sample implementation of the StockListDemo Data Adapter based on JMS;
it is in DOCS-SDKs\sdk_adapter_java\examples\StockListDemo_JMS_D ataAdapter in the distribution package.
