[jboss-user] [Datasource Configuration] - driver-class makes no difference

jepper [http://community.jboss.org/people/jepper] created the discussion "driver-class makes no difference" To view the discussion, visit: http://community.jboss.org/message/641770#641770 -------------------------------------------------------------- Hi I want to set up p6spy, but jboss is not using the pass thru driver it appears. My question is:      Is <driver-class> effectively ignored but it's presence required? Setup: jboss 6.1.0 final mysql 5.5 Both running on the same windows XP machine. CLASSPATH: D:\opt\jboss\jboss-6.1.0.Final\server\all\conf;D:\opt\jboss\jboss-6.1.0.Final\bin\run.jar D:\opt\jboss\jboss-6.1.0.Final\server\all\conf\spy.properties D:\opt\jboss\jboss-6.1.0.Final\server\all\lib\p6spy.jar D:\opt\jboss\jboss-6.1.0.Final\server\all\deploy\mysql-ds.xml It seems I can enter any random string in the <driver-class> tag. It makes no difference. I start jboss with a database with no tables. New jboss tables are created as expected, despite driver-class not being meaningful. If I delete the tag however, jboss complains and cannot speak to the database. mysql-ds.xml <datasources>   <local-tx-datasource>     <jndi-name>DefaultDS</jndi-name>     <connection-url>jdbc:mysql://localhost:3306/jbossdb</connection-url>     <driver-class>randomblah</driver-class>     <user-name>myuser</user-name>     <password>#</password>     <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>     <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>     <metadata>        <type-mapping>mySQL</type-mapping>     </metadata>   </local-tx-datasource> </datasources> mysql> show tables; +-------------------+ | Tables_in_jbossdb | +-------------------+ | hilosequences     | | timers            | -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/641770#641770] Start a new discussion in Datasource Configuration at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
