[jboss-user] [JBoss Seam] - questions about jboss embedded warns

Hi, Finally i run my jboss embedded on tomcat 6.0, but im warring about few warns. Can anybody explain me this anonymous wrote : | JBoss Messaging Warning: DataSource connection transaction isolation should be READ_COMMITTED, but it is currently NONE. | 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. | i added transaction isolation to my project-ds.xml like anonymous wrote : <transaction-isolation>TRANSACTION_SERIALIZABLE</transaction-isolation> | but don't know why still I get this warning? maybe for tomcat, transaction isolation should be in some other place? anonymous wrote : | (JBossTimerServiceFactory.java:restoreTimerService:112) -TIMER SERVICE IS NOT INSTALLED | WARN 14-08 14:07:53,656 (JBossTimerServiceFactory.java:restoreTimerService:112) -TIMER SERVICE IS NOT INSTALLED | Why I get twice timmer service warn? anonymous wrote : | WARN 14-08 14:08:08,515 (Component.java:checkScopeForComponentType:351) -Stateful session beans was bound to the APPLICATION context - note that it is not safe to make concurrent calls to the bean: collectionControler | what this means? and finally what this means? anonymous wrote : | WARN 14-08 14:06:56,406 (UnifiedLoaderRepository3.java:addClassLoader:675) -Tried to add non-URLClassLoader.
