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
