The Welcome Page, the Service Name Page, and the Finish Page are common to all adapter wizards. These pages are controlled by the Adapter framework, so you do not need to add them to the wizard, but there are accessor methods for overriding the contents of the Welcome Page (in the JcaAdapterWizard) and the Finish Page.
Framework pages must be extended by the adapter when you use them. A discussion of each type of extension follows.
