I am not sure whether this is the appropriate forum to post this. Please excuse me if I have made an error. I have been using HeadFirst Servlets and JSP and I compiled the code (the second version of the controller servlet).
I get the following error message saying that the package com.example.model does not exist. Please help me as I am unsure how to proceed with debugging this issue. I have pasted the error message below

D:\MyProjects\beerV1>javac -d classes src/com/example/web/
src/com/example/web/ cannot access
bad class file: .\src\com\example\model\
file does not contain class
Please remove or make sure it appears in the correct subdirectory of the classpath.

Just make sure your pacakge name matches the directory structure that the file is in and that your filename matches the class name of your class's signature.

Looks like you're compiling it as rather than com.etc.etc, as below. Not a stupid question, we've had this question a couple of times so I'll point it out to Bert and Kathy, maybe they can look at polishing these instructions in the next edition!

I agree. Here's the link:
