In the chapter Design Patterns, suddonly on page 729, the book says -
"To wrap up discussion on business tier patterns........"
and i got a shock, knowing that design patterns are classified into some types. The book never says you so, neither in the intorductory pages.
This is another case where the book is a bit dangerous.
i did lots of googling, and finally found that ( from a book Core J2EE� Patterns: Best Practices and Design Strategies, Second Edition - by
by Deepak Alur, John Crupi, Dan Malks ) design patterns are of two types -
1) Business Tier
examples are : Business Delegate, Service Locator, Transfer Object
2) Presentation Tier
examples are : Intercepting Filter, Front Controller
Hope this adds to the knowledge of all ranchers
By the way, i have made some notes from the book. i have uploaded the notes here
You can ignore the sequence disgrams, but i personally think that this material increases your comfort level in the topic.
Bert, i personally think that the book should have such first hand information ( the one that i keyed in above ) in it. also we would like to get some description explaining what the above two types means.
