Hi ,

I am doing the first web application given in the book.(HFSJ - page 84)

I am now trying to compile 'BeerExpert.java' file but i get error:
----------------------------------------------------------------------
C:\Program Files\Apache Software Foundation\Tomcat 5.5\Myprojects\beerV1>javac -
d classes src/com/example/model/BeerExpert.java
Note: src/com/example/model/BeerExpert.java uses unchecked or unsafe operations.

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....
