Package problem when compiling

Question

Hi,
I'm new to java. I'm using Win2000 and JDK1.3.1. I set the "c:\jdk1.3.1\bin" in the System's path. There are three java programs with their own package in the directory as follows:
"pack.java" - under "c:\jdk1.3.1\bin\test", it will call pack1 & pack2.
"pack1.java" - under "c:\jdk1.3.1\bin\test\sub1"
"pack2.java" - under "c:\jdk1.3.1\bin\test\sub2"
It's ok to compile "pack1.java" and "pack2.java" under their directory. But there is the compiling error for the "pack.java" under "c:\jdk1.3.1\bin\test", even though I've put the "import test.sub1.pack1;" and "import test.sub2.pack2;" in the code. The error were as follows:
- cannot resolve symbol
- symbol : class pack1
- location: package sub1
- import test.sub1.pack1;
- cannot resolve symbol
- symbol : class pack2
- location: package sub2
- import test.sub2.pack2;
I'm not sure what the problem is with the package and/or the import statement. Can any experts help me?
Thanks in advance.

Hi all gurus,
Thank you very much for the help!
After adding the classpath "c:\jdk1.3.1\bin" to the System's setting, I can compile the "pack.java" under the "test" directory with the command "javac -classpath c:\jdk1.3.1\bin c:\jdk1.3.1\bin\test\pack.java". However, when I run "pack" with the command "java -classpath c:\jdk1.3.1\bin c:\jdk1.3.1\bin\test\pack", there is another error appears as follows, although the "pack.class" has been already there:
- "Exception in thread "main" java.lang.NoClassDefFoundError: c:\jdk1/3/1\bin\test\pack"
My "pack.java" code is below:
package test;
import test.sub1.pack1;
import test.sub2.pack2;
class pack{
public static void main(String[] args){
System.out.println("Starting pack");
System.out.println("Instantiate obj of public classes in different packages");
//Instantiate objects of pack1 and pack2 in different packages.
new pack1();
new pack2();
System.out.println("Ending pack");
What's wrong with them? Could you please help me on that?
Thanks again!
