(I tried to find the notes for how to run this but did not see them, they are not in the readme.html but they might be on the wiki.) | | Did that. | | 2) Create a *-ds.xml file for MySQL (instructions are in the wiki, I already gave you the link). Do NOT use "DefaultDS" as the JNDI name unless you want to make a lot of other configuration changes; use amother name such as "MessagingDS". | | Did that. | | 3) Replace the deploy/jboss-messaging.sar/hsqldb-persistence-service.xml file (I hope I got this directory name correct) with the mysql-persistence-service.xml file from the [jboss_messaging]/examples/config directory. Edit this file to use the JNDI name you chose in step 2. The name appears several time, you will have to change it in every location. | | Did that.
