[jboss-as7-dev] "driver-name" attribute while creating the JDBC driver

I was trying out creation of a JDBC driver through the management operation. Initially I used this operation: [standalone@localhost:9999 /] /subsystem=datasources/jdbc-driver=mysql-5-driver:add(driver-module-name=mysql, driver-class-name=com.mysql.jdbc.Driver) Note that it _doesn't_ specify the "driver-name" attribute. However, it failed with: { "outcome" => "failed", "failure-description" => "JBAS014749: Operation handler failed: No child 'driver-name' exists", "rolled-back" => true } (the error message isn't clear by the way, but that's a different matter). I then had to change the operation to explicitly specify the driver-name attribute: [standalone@localhost:9999 /] /subsystem=datasources/jdbc-driver=mysql-5-driver:add(driver-name=mysql-5-driver, driver-class-name=com.mysql.jdbc.Driver, driver-module-name=mysql) That worked fine. But why is this operation unlike other "add" operations which use the value before the ":" as the name of the new resource? By the way, I even tried this command: [standalone@localhost:9999 /] /subsystem=datasources/jdbc-driver=foo:add(driver-name=bar, driver-class-name=com.mysql.jdbc.Driver, driver-module-name=mysql) Note that I use "foo" as the resource name for the add operation and "bar" as the driver-name attribute value. This creates a driver named "bar" in the standalone.xml: <driver name="bar" module="mysql"> <driver-class>com.mysql.jdbc.Driver</driver-class> </driver> and there's no reference to "foo" anywhere. So what's the significance of using it in the operation? -Jaikiran
