I've noticed that the j2ee reference implementation tools aren't always good about cleaning out old code when you make a change and redeploy. There is a cleanup batch file, try running that. Then rebuild and redeploy your ejb jar. Hopefully that will do the trick.

I did not meet your problems since I just download the new code from the author's website.

Howdy -- you can get the code from either the O'Reilly site or from:
wickedlysmart site
Just click on the Head First EJB book icon and you'll get the link to the code jar.
You really should keep the import statements!!
Cheers,

Kathy,
on what files is the HFECODE(jar file) built ,what method should my adviceclient have?is it getAdvice() or gettheMessage()?

[Kathy Sierra]

Howdy -- in the code jar file the method is NOT getAdvice(), but getMessage(). (Not, getTheMessage()). So that method name is reflected in the client code and the component interface as well.
cheers,
Kathy
