For anyone interested. In case you want to use JBoss Messaging in a standalone mode (like instructed by the Wiki) and you want to use Oracle, you need these following aditional steps. Edit messaging-standalone/conf/jboss-service.xml Add anonymous wrote : | | Copy standardjbosscmp-jdbc.xml to the same folder (conf) as the previous file. If you don't do this, then you will have a deployment error. Could someone from the Messaging team validate these instructions, and if so add it to the wiki? Was the only way I could get Messaging in a standalone environment while using an Oracle DB.
