Thanks for the book title. I will definitely look for it.
I am still using Java 1.1.8, so I don't think I can use EJBs. I have
called javaBeans from servlets many times, but not vice versa. I thought
perhaps once instantiated inside a jsp, a bean could call a servlet to
retrieve any needed database information. The reason I am looking at
servlets for this role is because jdbc code seemed to execute faster
in them than in beans or jsps.
Thanks again.
