Hello everyone,
I am new to JBoss and all appication servers in general. I followed a tutorial
and was able to build a .war file for deployment. When i tried to access the
deployed page, (or app i am unsure of the correct terminology), I received this
exception:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from
fulfilling this request.
