my hsl dialect is not overriden even when created portal_ext.properties web_inf /classes... plz give me a solution

Hi laxman,
Its portal-ext.properties not portal_ext.properties under WEB-INF/classes. Rename your file name and restart the server.

When using OS such as Ubuntu and other flavors of linux, please take care on upper/lower cases too as Juhi has it. Doesn't matter too much on Windows.
