Re: DB I/O

You can still do that.  Just write your bean to use a server to actually access 
the data.

Better yet, write your application code to use an interface rather than a 
particular bean.  This is a crucial tenet of OO programming.  Next you write a 
different bean that implements the same interface, but uses a server to access 
the data.  Now you can easily switch back and forth between the two without 
changing your application - a good way to do performance testing, among other 
things.  That's the beauty of OO design.

>One reason that I liked the bean method is that I now have a class that can
be used by any Java app.  I actually proved it to myself yesterday.  i had a
bean that accessed a file.  I used it in a servlet.  Then I started looking
into the XML classes.  I used that same "bean" to get data and build XML.
Brilliant, easy, etc.. etc..
