Tomcat Auth

[Renato Romano <r....@set-network.com>]

Is it possible to use different Authentication Realms for different
applications running on Tomcat4.0 ? Or at least use different DataBase,
tables etc... ?And if yes how ?
Thanks everyone.

Maybe it is possible in older versions of Tomcat ?

changing a user's password on linux using jsp exec.

Is it possible? I wrote this jsp file, but nothing
seems to happen. Any ideas?

Yes.  All you need to do is create a <Context> element in server.xml for
each element, and put the <Realm> element for that application inside it.
The gory details are in the Server Configuration Reference, which is
available once you start up Tomcat 4 at:

  http://localhost:8080/tomcat-docs/config/
