Question: Does the JMS Adapter support JMS topics (publish&subscribe)?

Answer: No. The JMS Adapter works with JMS queues because 100% Exactly Once (In order) service quality can only be guaranteed with JMS queues. See also: "Java Message Service", Monson-Haefel/Chappel, O'Reilly Publishers, 0-596-00065-5 2001, page 102 "... In this case, the once-and-only-once is in doubt".

Question: Can I release or read JMS message properties (for defining JMS message properties (see the above mentioned book, Appendix C)?

Answer: No, you cannot release JMS message properties. With XI 3.0 Support Package 12, a function was introduced for the correlation of messages, which allows you to create XI message IDs on JMS string properties. A JMS string property can be read in the same way to set XI message Ids.

Question: I have a problem and would like to use the J2EE logging for the analysis. How do I switch on the logging?

Answer: Start the J2EE Visual Administrator, select the J2EE service "Log Configurator" and select the "Locations" tab. Open the com->sap->aii->af->mp->jms->ejb there and set the log severity to "Debug" to log the JMS Adapter modules. Execute the same operation with the location com->sap->aii->af->service->jms if you want to log the JMS Adapter service.

Question: What is the com->sap->aii->adapter->jms logging location used for?

Answer: It is not used for anything. This location is obsolete and is not used. It is only visible under XI 3.0 Support Package 0 and Service Release 1 and unfortunately cannot be removed technically between Support Package s.
