Hi-
I have a legacy sybase database with group and role based info record for many users.
I would like to re-implement a sample tracking C app as a grails web app(maybe!).
The issue is the authentication against and use of the jndi datasource in my glassfish container,
and then the use of these credentials as the session.user as far as the grails app is concerned.
For one I have not seen a nice reliable way of modifying the web.xml file. Any ideas or
experiences out there?

thanks
Will
