To use the driver, the JAR archive named
postgresql.jar if you built from source,
otherwise it will likely be (named with the following convention:
postgresql-*[server version]*.*[build number]*.jdbc*[JDBC version]*.jar,
postgresql-8.0-310.jdbc3.jar) needs to be included in the class path,
either by putting it in the
CLASSPATH environment variable, or by using flags on
the java command line.
For instance, assume we have an application that uses the JDBC driver to access
a database, and that application is installed as
PostgreSQL™ JDBC driver installed as
To run the application, we would use:
export CLASSPATH=/usr/local/lib/myapp.jar:/usr/local/pgsql/share/java/postgresql.jar:. java MyApp
Loading the driver from within the application is covered in Chapter 3, Initializing the Driver.
