How can I compile program which uses packages?

Question

Hi,
I'm building a program using JBuilder9. I can successfully run using that IDE, but after I try to run it manually (run class file which compiled from JBuilder) by typing "javac myMainClass" it cannot find serveral packages which I put those packages' folder on the same root directory of myMainClass. Thank you.

Man, you should probably read the following:

Anyways, the first thing to do is to determine the current value of CLASSPATH (that is a system variable and it depends on your OS how you change/get its value).
Next thing is to determine WHAT you need to add:
For each used package check if its (root directory/jar) is in your CLASSPATH. If not add it, e.g.
- you have a package my.test.package in C:\temp\myJar.jar then add C:\temp\myJar.jar
- you have a package my.test.package in C:\temp, i.e. your fs structure is C:\temp\my\test\package, then add C:\temp
For beginners, it's usually a good idea to have your CLASSPATH contain a dot (".") ...
