Hi Pat,
There has been a lot written about this over the last 6 months in the
JSP-INTEREST mailing list. I would recommend searching the archives for
"architecture". As a matter-of-fact, I did this a couple of days ago and
saved one of Craig McClanahan's very informative postings on his ideas for
Servlet-JSP integration, including the command pattern. The post can be
found at the following link:
http://archives.java.sun.com/cgi-bin/wa?A2=ind9911&L=jsp-interest&D=0&m=6166
&P=107101
I would recommend that whole thread to anyone interested in JSP/Servlet web
app architectures. I have also seen recent articles on the JavaWorld site
(http://www.javaworld.com) on what I think they call the "event delegation
model" for servlet interaction.
Finally, I have recently reviewed an upcoming book from Manning Publishing
called "Web Development with Java Server Pages" by Duane Fields and Mark
Kolb. This goes into some detail about web app architectures and includes a
fairly thorough example of the using the command pattern with a single
controlling servlet. The book will be out in the next few months, but I
think you can get a sneak peak at:
