createApplicationParentCL

public ClassLoader createApplicationParentCL(ClassLoader parent,
                                    org.glassfish.api.deployment.DeploymentContext context)
                                      throws com.sun.enterprise.module.ResolveError

Sets up the parent class loader for the application class loader. Application class loader are under the control of the ArchiveHandler since a special archive file format will require a specific class loader. However GlassFish needs to be able to add capabilities to the application like adding APIs accessibility, this is done through its parent class loader which we create and maintain.

Specified by:

createApplicationParentCL in interface org.glassfish.internal.api.ClassLoaderHierarchy

Parameters:

parent - the parent class loader

context - deployment context

Returns:

class loader capable of loading public APIs identified by the deployers

Throws:

com.sun.enterprise.module.ResolveError - if one of the deployer's public API module is not found.
