Server config guide: Appendix B.7.2. The More Flexible Way

The below
jboss-as/server/production/jms/hsqldb-jdbc-state-service.xml and jboss-as/server/all/deploy-hasingleton/jms/hsqldb-jdbc-state-service.xml: Those files configure the JMS persistence service as we discussed earlier.

should be replaced with:
jboss-as/server/all/deploy/jboss-messaging.sar/clustered-hsqldb-persistence-service.xml: Those files configure the JMS persistence service as we discussed earlier.
