Hi all
I am trying to execute the Prim Numbers example given in i am getting errors when compiling file. the errors I got are

javac Undefined variable or class name: Primes
BigInteger start = Primes.random(numDigits);
^ Undefined variable or class name: Primes
start = Primes.nextPrime(start);

My guess is that Prime is another class that they wrote which is not available in your classpath. You should compile them all at once rather than one at a time.

javac *.java

Just make sure all the java files for every class you need to compile that is referenced is in the default directory.

Hope this helps...

Each chapter in that book builds on previous chapters.
Look back in the book for the first chapter that builds an app that displays prime numbers.

Build that class and make sure it's on your classpath.

BTW: One of the things that I love about that book is that he teaches the aspects of Servlet/JSP programming in just the right order. It's worth the time to go through the whole thing in order.
