I have the same question. I have an app written to Hypersonic and now need to translate the db configs to use SQL Server 2005 with jdts. I have the following config but getting an error in the mbean code="org.jboss.jdbc.SQLServerDatabase" line. I just guessed at that. It used to say HypersonicDatabase: <local-tx-datasource> <jndi-name>myDS</jndi-name> <connection-url>jdbc:jtds:sqlserver://mymachine:1433/mydb</connection-url> <driver-class>net.sourceforge.jtds.jdbc.Driver</driver-class> <user-name>sa</user-name> mypass <min-pool-size>5</min-pool-size> <max-pool-size>20</max-pool-size> <idle-timeout-minutes>0</idle-timeout-minutes> <track-statements/> <type-mapping>SQL Server</type-mapping> jboss:service=MSSQL-db,database=mydb </local-tx-datasource> 1701 true mydb false true View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4167171#...
