Your classpath is not setup properly.
Specifically, the directory that houses your packages needs to be on the classpath.

Javaranch has an excellent article on classpaths.
There is a lead-in to it in the servlets faq.

hey Anand i got that same problem just a few days ago.

assuming u use the same directory stucture as is given that book ,u set ur classpath as follows

classpath = %classpath%;D:/MyProjects/beerv1/classes;

U make necessary changes if its isn't in 'd' drive. Hope for the best.

keep in contact with me. We are sailing in the same boat....
