David,
Thank you for your response. Unfortunately, I did not express the question adequately. I understand that the book does not sell me on Glassfish, you already explained that in the other thread.
I want to know if the book explains what makes "Java EE technologies and APIs such as EJB's, JAX-WS, JPA, etc..." a worthwhile investment.
So for example, does it describe a scenario using
JDBC or some ORM and explain how a migration to EJB and/or JPA provides better performance or cleaner design or easier maintenance or whatever.
If a business has a custom protocol between hosts that exchanges information through secure ftp of configuration files or http posts across an https connection, does the book explain how moving to JAX-WS or JMS offers some clear advantages?
etc... etc...
Does that clarify the question?
Hibernate In Action by Christian Bauer and Gavin King starts off with a good chapter explaining what Hibernate is, what ORMs are, and what advantages you get by using Hibernate instead of just writing your own custom JDBC code for each project. I want to see if your book does something similar. With Java EE.
