Kaj (et al),
There is a great article in June 2000 Java Developers Journal -- Applying
Patterns to JDBC Development by Christian Thilmany -- mentions several
patterns for JDBC and, by extension, EJB. He used two general sources:
"Design Patterns: Elements of Reusable Object-Oriented Softwared" from the
GOF (Gamma, Helm, Johnson, and Vlissides)
"Patterns in Java" (3 volumes) by Mark Grand.
Personally, I find Mark Grand's more accessible (being Java oriented and
with more coding examples). He also covers more "real world" stuff. First,
look at the article in JDJ (for a price, you can get the article at
http://www.sys-con.com/java/index2.html or just go buy the current issue).

Subject: Design guide for EJB / Building patterns
Hi,
I would like to know if there are any good books on how to design with EJB.
I've heard that it is common to use stateful session bean to do multiple
(database) selects, and that you only create the entity beans when you want
to write data.
I guess that this is done the decrease network load.
I've also heard that you never should access an entity bean without going
through a stateful session bean (which should act as a fa�ade). Is this
true?
What other design rules are there? Where can I find more info about them?
(Books, links etc.)
I would also like to know if there are any advanced EJB programming books.
The only book I got is "Mastering Enterprise JavaBeans and the Java 2
Platform Enterprise Edition". And I would like to buy a book that is a litle
bit more in depth (and only covers EJB 1.1). What book to choose?
Thanks
/Kaj
