Hi Beny,

Assuming myjar.jar is in c:\jardir and Engine.class in c:\classdir, and those files are needed in order for Car.java to compile successfully. So you use "classpath" option to tell the compiler where to look for those files. Car.java is stored in c:\workarea directory.

c:\workarea>javac -classpath c:\jardir\myjar.jar;c:\classdir Car.java

For Windows, use semicolons to separate the classpath as shown in the example above; for Solaris, use colons. For more info, see Windows: classpath and Solaris: classpath.

There are some rules you need to follow when setting the classpath.
Quote from Solaris: classpath (same for Windows):

For a .jar or .zip file that contains .class files, the class path ends with the name of the .zip or .jar file.

For .class files in an unnamed package, the class path ends with the directory that contains the .class files.

For .class files in a named package, the class path ends with the directory that contains the "root" package (the first package in the full package name).
