The name of the Java JDBC driver to connect to a database.

Key: db.jdbc_class
Type: String
Can be set in: collection.cfg


This parameter specifies the database JDBC driver class which should be used to connect to the database. The value should be a fully qualified class name, which must have been installed as described below.

Installing JDBC drivers

Most JDBC drivers ship as a .jar (java archive) file. Funnelback is configured to automatically make all .jar files installed in certain locations available to the database gathering components.

To install a JDBC driver, simply copy the .jar file to the following directory (where [INSTALL_ROOT] is the directory that Funnelback has been installed in):


When installing drivers be careful to install only one version of any particular driver to avoid any Java errors relating to duplicate class definitions.
