The JDBC driver is a jar library that allows Portofino to communicate with the database. The driver is not part of Portofino's distribution. Refer to your database's documentation to learn how to obtain the JDBC driver and a suitable license.

Once you have the driver, you must copy its jar file to the application server's library directory. The following table summarises the typical location for the various application servers.

Application server	Typical library directory
Tomcat 5.5	CATALINA_HOME/common/lib/
Tomcat 6	CATALINA_HOME/lib
JBoss	JBOSS_HOME/server/default/lib/
Glassfish	GLASSFISH_HOME/domains/domain1/lib/
OC4J	ORACLE_HOME/j2ee/home/applib/

After you have installed the driver, restart the application server to make sure that the library is loaded.
