Hi, quite a good book huh ?;-) I agree with a lot of things Christian mentioned. I think its the "Fast Lane" rather than "Fast Track" :-)

I think you may have slightly mis-understood, the comments in the book (I think I know the comments you are referring too, if not, excuse me!). There is some overhead using EJBs, especially since all the SQL is generated by the EJB containers. Of course there is a lot of functionality provided by this too. In the book, what is discussed is the fact that SOME database access (especially tabular data) can be slow. The common J2ee way around this is to use the Fast Lane read pattern, http://java.sun.com/blueprints/patterns/FastLaneReader.html Another issue talked about in the book was a method of increasing performance of EJBs by using value objects, reducing network traffic by creating a object with all your data to pass to your EJBs instead of multiple calls e.g. create value object field1 => value1 field2 => value2 field3 => value3 field4 => value4 field5 => value5 pass object to ejb method myejb.setValues(myvalueobject) results in one RMI / network call opposed to myejb.setfield1(value1) myejb.setfield2(value2) myejb.setfield3(value3) myejb.setfield4(value4) myejb.setfield5(value5) results in 5 rmi calls. There are lots of different way of doing database work in EJB, CMP , BMP , JDO , persistence frameworks etc ... also remember the J2EE/MX book tries to show Java developers, way the should use CF/Java v's Java alone, and IMHO, sometimes falls on the side of CF..
