Hi,

My question is if it is possible to use dsp tag libraries from ATG outside gears i.e., for a normal jsp.

I thought it should be possible but whenever i try that it gives me a null pointer exception. What I am tring to do is as follows couldnt be simpler than that


<%@ taglib uri="/dsp" prefix="dsp" %>
<dsp:page>
</dsp:page>

but on accessing this webpage I get the following exception
