Using the Common Class Loader

To use the Common class loader, copy the JAR files into the domain-dir/lib or as-install/lib directory or copy the .class files (and other needed files, such as .properties files) into the domain-dir/lib/classes directory, then restart the server.

Using the Common class loader makes an application or module accessible to all applications or modules deployed on servers that share the same configuration. However, this accessibility does not extend to application clients. For more information, see Using Libraries with Application Clients.

For example, using the Common class loader is the recommended way of adding JDBC drivers to the Enterprise Server. For a list of the JDBC drivers currently supported by the Enterprise Server, see the Sun GlassFish Enterprise Server v3 Release Notes. For configurations of supported and other drivers, see Configuration Specifics for JDBC Drivers in Sun GlassFish Enterprise Server v3 Administration Guide.

To activate custom login modules and realms, place the JAR files in the domain-dir/lib directory or the class files in the domain-dir/lib/classes directory, then restart the server.
