Sorry, here's the stacktrace http://pastebin.com/1v4Tmujq
I followed the instructions and the only changed made were to add the username and password into the resources.properties
// also tryed with the MySqlXADatasource
resource.ds.className=bitronix.tm.resource.jdbc.lrc.LrcXADataSource
resource.ds.uniqueName=jdbc/testDS1
resource.ds.minPoolSize=0
resource.ds.maxPoolSize=5
resource.ds.driverProperties.driverClassName=com.mysql.jdbc.Driver
resource.ds.driverProperties.url=jdbc:mysql://localhost/jbpm
resource.ds.driverProperties.user=testing
resource.ds.driverProperties.password=testing
But I can't see the registered datasource in the tomcat jndi manager.
