Tomcat JNDI Realm on iSeries

Hi,

We have an intranet solution, recently running on a WIN NT machine
that displays and manipulates AS/400 data. Now we installed a Tomcat
standalone version 4.1.24. There was no problem with deploying of the
application except that we'd had to remove Java 1.4 features because
of the lower version of Java on AS/400.
Now we hve some issues to solve for best performance and admin
capabilities:

1.) achieve a single-step login to the application that would be equal
to AS/400 login, and also to use this login information to AS/400
database.
Till now we had a memory realm on the tomcat, and had only one common
as400 user name and password stored in the web.xml as init parameter.
This was OK. for testing purposes, but not good for the company
security requirements. As I've read a JNDI realm has to be configured,
but I don't know how to configure it.

2.) create a connection pool based on the sign-on JNDI configuration
that would application-wide manage database connections for all users.

Thank you for your answer it will help me a lot
