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].[buildnumber].jdbc[JDBC version].jar,
for example 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 /usr/local/lib/myapp.jar. The PostgreSQL JDBC driver installed as /usr/local/pgsql/share/java/postgresql.jar. 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 the Chapter called Initializing the Driver.
