Hi Everybody I am using JBoss4.0.4.GA and JBoss Messaging (jboss-messaging-1.0.1.GA) and MySql (mysql-5.0.22-win32) .I did all the modification that needs to be there for proper working JBoss Messaging Server with Jboss AS. When i start my application server with the option run -c messaging I get the following warning ...Just warning only JBoss Messaging Warning: DataSource connection transaction isolation should be READ_COMMITTED, but it is currently REPEATABLE_READ. Using an isolation level less strict than READ_COMMITTED may lead to data consistency problems. Using an isolation level more strict than READ_COMMITTED may lead to deadlock. Can anybody tell me in which config file, i should do the modification to make the transaction isolation to be "READ_COMMITED" I would appreciate if you could able to provide me a way to change this configuration.
