Message:

need to include import com.bruceeckel.swing.* ?? how

Posted by Matt Gerrans on November 30, 2001 at 12:56 PM

Everything you need is included in the source code zip file you downloaded. When you unzip it, there will be a com directory, among others. The directory where you unzipped the code needs to be added to your classpath environment variable.

If you want to be tricky, you can just add ".." to your classpath, then when you are in any of the directories with a particular chapter's code the compile will correctly resolve it, as well (but there are a few where there is more code in subdirectories of the chapter, which means you'd need to add "../.." to the classpath).

Generally speaking, if you have a package import, eg:
import com.co.pack.*;
and the files are in (with Windows platform syntax):
c:\somepath\com\co\pack
then your classpath needs to include c:\somepath. If your classpath is not currently empty, then you add an item to it like this (on the command line):
set classpath=%classpath%;c:\somepath
If the package is in a jar file, then the classpath needs to contain the fully qualified name of the jar file (not just its path).
