Subject My LoginView.jsp Displays A Blank Page
Date Sun, 06 Jul 2003 00:21:00 GMT
My LogonView.jsp displays a blank page.  I have no
idea why nothing is written while the
MessageResources.properties file is found.
 
I would have gotton HTTP Status 500 if the
MessageResources.properties is not found or the value
of the corresponding key in the bean:message tag
cannot be picked up.  I did not get any error message.
 I cannot figure out the reason.  Please help.

Here is my web.xml file:
