Freddy,
You may want to take a look at Hibernate (http://www.hibernate.org), if you
haven't done so already.
Hibernate is a persistence mechanism which utilizes XML mappings to map
Java objects to relational database schemas, and does support cascading
deletes, amoung other things.

I believe the point Kris was trying to make is that, in addition to using

generate your XSLT stylesheets. This functionality is seperate from JSTL

LDAP, as the name implies, is a Directory Access Protocol. As such, you
cannot use JDBC to establish connections. However, java does provide an
analagous interface for accessing Naming and Directory Services (LDAP, DNS,

Makes sense.
I'm guessing you have something like:
int num = rs.getDouble(1);
From your earlier e-mail, it looks like num is actually a long (i.e., it is
a whole number that will not fit into Java's 32-bit int). Try this
instead:
long num = rs.getLong(1);

This probably goes without saying, but in addition to being UI agnostic,
your business logic should also be datastore agnostic. To be truly
abstract, it should be as easy to move your backend from RDBMS to LDAP or
XML as it is to move the UI from Web to GUI to Console.
