To use the System Classloader, do one of the following, then restart the server:
Use the Administration Console. Select the JVM Settings component under the relevant configuration, select the Path Settings tab, and edit the Classpath Suffix field. For details, see the Sun Java System Application Server Enterprise Edition 8.2 Administration Guide.
Edit the classpath-suffix attribute of the java-config element in the domain.xml file. For details about domain.xml, see the Sun Java System Application Server Enterprise Edition 8.2 Administration Reference.
Using the System Classloader makes an application or module accessible to any other application or module across the domain.
Add the classes to the classpath-suffix attribute of the DAS in addition to the classpath-suffix attribute on the server instances that use the classes. The default name for the DAS configuration is server-config.
