Hi,

I can't find an element "run" in the webapp 2.2 DTD. Could you give an example/some context?

[Madhav Lakkapragada]

Thats a 2.3 Servlet Spec feature.
Not in 2.2

From the DTD

<!--
The run-as element specifies the run-as identity to be used for the
execution of the web application. It contains an optional description, and
the name of a security role.
Used in: servlet
-->
<!ELEMENT run-as (description?, role-name)>

Check out the Servlet spec for more details on the security model of Servlets.

Thanks,
Actually I am going through the servlet 2.3 specification and I wanted to know the use of this particular element.
I found a helpful article over
here
It looks as if I have to look at the J2EE spec 1.3 to look at this element.
