uninstallList Element

The <uninstallList> element is a child of the <component> element and contains one or more named uninstall step blocks, each providing a different way to uninstall this component. Many components will have only one uninstall block as a child of this element. Multiple uninstall blocks can be used when different steps are required for different installation environments. For example, steps to undeploy an EBJ app from a server cluster versus undeploy from a single managed server. Uninstall blocks often correspond one to one with install blocks, and in such cases, by convention use the same name to indicate the correspondence.

uninstallList Inheritance and Overriding

By default, a derived component inherits the accessible <uninstallList> element contents of its base component. When a derived component declares an <uninstallList>, its contents are effectively merged with those of the base component. The derived component may declare new <uninstallSteps> elements and override inherited ones, but may not remove elements declared by the base component.
