A very different approach from the one that you are used to, but which is
explicitly  supported by Tomcat, is to use the JDBCRealm class to perform
user authentication in which you look up authentication credentials in an
ODBC database.

You can use either basic authentication, in which the browser obtains the
authentication info, or form based in which you prepare a (jsp based) form
of your own devise. You must configure Tomcat in the server.xml file to do
this and you must configure the application in the web.xml file. In the
latter you can specify collections of URL resources that need be
authenticated and user roles (i.e authentication levels) that can have
access to them. Finally, you need an ODBC compliant database and JDBC
