Subject: RE: Finding app context in action class???
This is close, but I am hoping to accomplish with just an Action class.
I dont want to extend my class into any form of ActionServlet , servlet,
or anything like that. Is it possible to get access from an Action page
the way you can get access to the session?

This is how i've used the context in my application. It loads
objects(say
collections) into servletContext.
In struts you would refer them as :
<html:select property="severity">
<html:options name="severityList"/>
</html:select>
Hope this is what you are looking for ?? Any comments..
