Greetings,

In the release version of the Programmer's Guide, the chapter on JDBC
(I used the one at
http://www.postgresql.org/users-lounge/docs/7.0/programmer/jdbc6424.htm
)
has an example of using the class loader to load the Postgres JDBC
driver that uses the incorrect driver class name:

Class.forName("postgresql.Driver");

This same error is repeated in the example for loading the driver using
the command line switch:

% java -Djdbc.drivers=postgresql.Driver example.ImageViewer

The correct driver class (at least in the latest release with the filename
jdbc7.0-1.2.jar, obtained from Peter Mount's site at
http://www.retep.org.uk/postgres/download.html) should be
org.postgresql.Driver, thus changing the docs to read

Class.forName("org.postgresql.Driver");

and

% java -Djdbc.drivers=org.postgresql.Driver example.ImageViewer

Following the docs will cause the code to throw an exception with the
message "java.lang.NoClassDefFoundError: postgresql.Driver".

In the future, should we submit SGML diffs?

Jeff
