I am unable to run the servlet version 2 given on page 85(of Head First Servlets and JSP 2nd edition) even after building the directory structures as shown in the book. Specifically, i am unable to compile the servlet called BeerSelect.java. The error shown is "unable to find package com.example.model.*". I have checked and rechecked the directory structures. I am compiling the servlet from MyProjects/beerV1 directory with the command "javac -d classes src/com/example/web/BeerSelect.java" as i have already set the classpath elsewhere. Moreover version 1 of the same servlet is running fine.
Also i would like to report that the deployment descriptor given on page 30 in chapter 1 of the same book does not work well. Tomcat 5.5 shows error in the first line of the web.xml file i.e. "<?xml version=�1.0� encoding=�ISO-8851-1� ?>". Upon removing this line the servlet runs fine.
Please help guys.

I have copied servlet-api.jar and jsp-api.jar files in the C:\Program Files\Java\jdk1.5\jre\lib\ext directory. This serves the same purpose. Moreover, rest examples are running fine i.e. chapter1,2,3.The problem is with this one only.
You said that you are compiling like this: "javac -d classes src/com/example/web/BeerSelect.java" So the directory you are in must look like this: MyProjects/beerV1/src/com/example/web/BeerSelect.java BeerSelect.java must try to import "com.example.model.*" which is probably found at: MyProjects/beerV1/src/com/example/model/ The problem is that com.example.model is NOT in your classpath. Your classpath begins in the MyProjects/beerV1/ directory (because that is where you are when you run the javac command) and the package is in the MyProjects/beerV1/src/ directory.
Try running javac from inside the MyProjects/beerV1/src/ directory and compile with: "javac -d classes com/example/web/BeerSelect.java"
That should fix the problem. [ August 07, 2008: Message edited by: Steve Luke ]
