404 error handling

Hi,

I have added custom error scripts in /apps/sling/servlet/errorhandler(404.jsp,default.jsp).

If I try to request below page on AEM 6.1 instance which doesn't exist:

https://localhost:4502/es_ES/hello  -    my personalized 404 page is displayed.

But if i request below page :

https://localhost:4502/hello            -    no error is showing up. Page is coming blank.

In httpd.conf i am configuring my error document like below:

<LocationMatch> \.html$

ErrorDocument <path of the error page>

</LocationMatch>

Please help me in resolving this issue. 404 page needs to be effective at the root context also.
