To use the System class loader, do one of the following, then restart the server:
Use the Admin Console. Select the Application Server component, select the JVM Settings tab, select the Path Settings tab, and edit the System Classpath field. For details, click the Help button in the Admin Console.
Edit the system-classpath attribute of the java-config element in the domain.xml file. For details about domain.xml, see the Sun Java System Application Server Platform Edition 9 Administration Reference.
Using the System class loader makes an application or module accessible to any other application or module across the domain.
