To use the driver, the JAR archive named
postgresql-MM.nn.pp.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-42.2.15.jar:. java MyApp
Current Java applications will likely use maven, gradle or some other package manager. Use this to search for the latest jars and how to include them in your project
Loading the driver from within the application is covered in Chapter 3, Initializing the Driver.
