You must also configure messaging and quartz to use the postgresql database. For messaging, copy the docs/examples/jms/postgresql-persistence-service.xml file to server/xxx/deploy/messaging and remove the hsqldb-persistence-service.xml file. Also, you must edit the file if you are not using clustering - see the comments in the file for details. For Quartz, see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=141835 I have complete, detailed, instructions for replacing Hypersonic, but it is not free. I can provide the URL if you are interested. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4178148#...
