This is how exceptions are handled

This is how WcmController.java, the "Controller" part of FileNet Workplace's implementation of MVC pattern, handles exceptions:

First, declare this:

  private Exception            configureWindowIdException = null;

Then, in ConfigurePage function, do this:

  public void configurePage(ServletContext applicationValue, HttpServletRequest request, long windowIdMode)
      throws Exception
{
          ... skipped ...
      configureWindowId(request);

      //  If configureWindowId constructed an exception, throw it.
      if ( configureWindowIdException != null  )
      {
           if ( !sp.isSignedIn() )
           {
               // We attempted to propogate a window Id when not signed in
               // probably the result of signing out of an info page.
               // Don't throw.  Fix the windowId to mainWindow instead.
               //
               WindowID assignedId = new WindowID(null);
               WindowID currentId  = new WindowID(null);

               assignWindowId(assignedId, currentId, false);
               configureWindowState();
               postProcessWindowId(assignedId, currentId, currentId,
                                   false, false, false, false, false);
           }
           else
               throw configureWindowIdException;
      }
          ... skipped ...
}

What about good old try-catch?

There is no proper exception handling in Workplace. Should I send this piece to The Daily WTF?
