This is an excellent book on almost all essential topics of the java Enterprise usage. I want to add three suggestions and hope to be added in the next edition:

1.) A seperate section at the end of the JNDI chapter on DataSource and ConnectionPoolDataSource interfaces.

2.) A companian examples book: java Enterprise in a nutshell. Similar to Java in a Nutshell.

3.) A complete working example (e.g. e-Commerce) to demonstrate the interplay among the JavaEnterprise components (in the examples book).
