How do I configure ant for the sources of Thinking in Java's book? [message #156896]

I have downloaded the sources from Thinking in Java's book written by
Bruce Eckels and I've used the Eclipse editor to run some classes. My
question is
how to include and build the classes that come with these sources inside
Eclipse?. I've tried to used the External tool from Eclipse but it
didn't work. The error that I have is

JDK.version.check:
[javac] Compiling 1 source file
[javac] BUILD FAILED: file:C:/Program
Files/eclipse/plugins/Code/c02/build.xml:31: Unable to find a javac
compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK

I know that I have to set the CLASSPATH but I don't know how. It is
clear that Java doesn't recognize the path indicated by the .xml file.
So, could you explain me which CLASSPATH file update and how must I
accomplish the task.
However the rest of the classes that come with Eclipse are well pointed
out by the external tool.
Regards,

Pepe

Add the appropriate tools.jar from your JDK install
http://www.eclipse.org/eclipse/faq/eclipse-faq.html#users_16

Or simple start Eclipse using the -vm option to point to your JDK install
http://help.eclipse.org/help21/index.jsp?topic=/org.eclipse. platform.doc.user/tasks/running_eclipse.htm

Or (in 3.0 later builds) set your JAVA_HOME environment variable to point to
your JDK install
