Please explain this classpath

[Mr Iftikhar]

I have a .java file on drive c
c:\packageA\ClassA.java
And another file on drive d
d:\packageB\ClassB.java
//******************************************************
//************** ClassA's structure ********************
//******************************************************
package packageA;
public class ClassA{
public static void print(){
System.out.println("ClassA's method print");
}
}

//******************************************************
//************** ClassB's structure ********************
//******************************************************
package packageB;
import packageA.*;
class ClassB extends ClassA{
public static void main(String args[]){
print();
}
}

Can i compile both files simultaneously on d:\ prompt ?
How i will set the class path?
How i will run the ClassB.class (consist main method) file?
Is this right way please guide.
set classpath = c:\jdk1.3\bin;c:\packageA;c:\packageB
d:\packageB\javac ClassB.java
is giving the error in ClassB packageA is not exist.
I am a java programmer but i am not success to solve this problem.
please help me.
Thanks in advance.

You need to explicitly indicate your classpath to the compiler. Try
javac -classpath C:\packageA;D:\packageB ClassB.java
(You did say that the packages were on different volumes C&D)
Good Luck!

packages names will be added to each entry in the classpath to look for the classes.
Thus if classpath contains c:\packageA and class ClassA is on packageA that will result in c:\packageA\packageA\ClassA, which is not correct.
Try seeting classpath to c:\

ugh, yes you're right Jose. my bad....must be 4am ;p
he's got two different packages on two different volumes so he's still going to have to include them individually:
javac -classpath C:\;D:\ ClassB.java
and of course this assumes that your working directory when you call javac is the same directory where the ClassB.java file is.
