Hi, I am using JAAS to pass the password and username of the user to the JDBC driver. The problem I get is I when the server starts it connects to the database but has no username or password and fails. Basically with this exception. | 10:55:57,197 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null | org.jboss.resource.JBossResourceException: No matching credentials in Subject! | I need to provide a default username and password so startup can connect to the database server and have no idea how I can configure JAAS to do this. This is my datasource config <local-tx-datasource> <jndi-name>MYDS</jndi-name> <!-- domain should be the windows domain the sql server is on --> <connection-url>jdbc:jtds:sqlserver://myserver:143/Coors;domain=MY.DOMAN</connection-url> <driver-class>net.sourceforge.jtds.jdbc.Driver</driver-class> <user-name>user</user-name> user <security-domain-and-application>PAE</security-domain-and-application> <check-valid-connection-sql>SELECT 1</check-valid-connection-sql> <type-mapping>MS SQLSERVER2000</type-mapping> </local-tx-datasource> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174671#...
