A simple generic way is to use a filter which executes on all requests.

If the ServletContextListener has an error - it can set a variable in the application context.

Then the filter can check for the existence of that variables. Then forward to an "error page".

For example ...
doFilter( ... ) {
   if (null!=servletContext.getAttribute("startupError")) {
       servletContext.getRequestDispatcher("/WEB-INF/error.jsp")
          .forward(request, response);
   } else {
       chain.doFilter(...);
   }
}

Seems like a simple question, can't seem to find the answer...


If an error occurs in the #contextInitialized() method of an object that implements ServletContextListener, how can I suspend the web application so that it is unavailable for use by clients?

Specifically, I have a ServletContextListener that needs to be run at application startup. If any one of many errors occur, I want to notify the appropriate people (this I can do) and make the entire webapp unavailable (this I can't figure out).

Any help is appreciated. I have a feeling this is obvious and I'm just missing something.
