getInitialPage

public String getInitialPage(javax.servlet.http.HttpServletRequest req)
                      throws DataEngineException

Force subclasses to return an initial jsp/servlet. We need this incase potential errors timeout occur while running generic services. For example, the web browser brings up a page and then sits for 5 hours then tries a DataEngineServlet service method such as sorting. The DataEngineServlet session has been lost (invalidated) so we are dead in the water so we'll ask the subclass servlet where we should take the user to resignon.

processRequest

public void processRequest(javax.servlet.http.HttpServletRequest req,
                           javax.servlet.http.HttpServletResponse res)

                           IOException

Description copied from class: DataEngineServlet

Parameters:

req - request

res - response
