Provides facilities for managing JDBC drivers.
The DriverManager
class loads JDBC drivers during its initialization,
from the list of drivers referenced by the system property "jdbc.drivers"
.

From class
java.lang.Object
|
Removes a driver from the DriverManager
's registered driver list.
This will only succeed when the caller's class loader loaded the driver
that is to be removed. If the driver was loaded by a different class
loader, the removal of the driver fails silently.
If the removal succeeds, the DriverManager
will not use this
driver in the future when asked to get a Connection
.
driver | the JDBC driver to remove. |

SQLException | if there is a problem interfering with accessing the database. |

info | a set of properties to use as arguments to set up the
connection. Properties are arbitrary string/value pairs.
Normally, at least the properties "user" and "password" should be passed, with appropriate settings for
the user ID and its corresponding password to get access to
the corresponding database. |
