Registering References 

Use

In the J2EE Engine class loading system, two types of references are available: component and application.

Both J2EE Engine components and deployed applications have a set of default references to services, libraries, and interfaces that are loaded each time the component or application is started. At runtime, you can modify these default references and add new references if necessary.

Typically, you do not need to modify the default component references.

This procedure demonstrates how you modify the default application references.

Procedure

Modifying Application References

You can add, edit, and remove application references at runtime through Telnet by using the CHANGE_REF shell command from the DEPLOY group of shell commands.

For more information about using the CHANGE_REF shell command, see DEPLOY (in the Reference Manual).

For more information about connecting via Telnet, see Connecting and Working Using Telnet.

Modifying Component References

Component references are registered/modified when the corresponding component is deployed/redeployed on the J2EE Engine. The modification must be done within the corresponding deployment descriptor.

Modifying component references manually might lead to problems within the J2EE Engine and is therefore not recommended. If you nevertheless need to modify component references manually without redeploying, see SAP Note 857025.
