Method Detail

processRequest

public void processRequest(PageContext pc,
                           String continuePage)
                    throws PageProcessorException

Description copied from interface: ReloadPageHandler

Requests that the reload/refresh warning page be shown. The continuePage indicates the page that the "no reload" page should provide a link to for the user to "continue" on to after reading the warning.

Specified by:

processRequest in interface ReloadPageHandler

Parameters:

pc - context of the current request/response cycle

continuePage - the page to link to from the warning page. If null is passed in, then the link will be to the original requested page that was part of the reload triggering.

Throws:

PageProcessorException

processRequest

public void processRequest(PageContext pc,
                           HTMLElement con)
                    throws PageProcessorException

Description copied from class: HTMLObjectsPageHandler

This method is called whenever there is a request aimed at this page. Subclasses override this method and fill up the specified container: con with the main content of the page. The subclass should then call HTMLObjectsPageHandler.sendPage(PageContext, HTMLElement) to deliver this page to the browser.

This class' implementation (when not overridden) always throws a PageProcessorException to indicate that the page is not permitted to be accessed directly. Subclasses override this method to allow a page to be directly requested.

Overrides:

processRequest in class HTMLObjectsPageHandler

Parameters:

pc - the context of the request/response cycle

con - the container to fill up with the page's content

Throws:

PageProcessorException - can be optionally thrown to indicate that the page could not be created.

                    throws PageProcessorException

Throws:
