The best way to get an answer to your question is to post everything you
can. Post the exact command line you are using, the output from it.
Post your directory structure, and which files exist where. In your
case, post the package declaration of your java source files as well.

Re: java CLASSPATH Environement var

//the super classe



package myPackage;

public class firstClass

{
//class data
int dataField_One;
int dataField_Two;



public firstClass ()

{

//constructor declaration

}



} //end firstClass



---------------------------------------------



package myPackage;

import java.awt.*;

public class DrawClass extends firstClass
{
//class data

//private declaration


//methods
//constructors
public DrawClass()// constructor

{

//constructor declaration

}



//other declarations

} //end DrawClass

----------------------------------------------
my directory files located in the directory named as the package name is:

myPackage.

The files are: firstClass.java (the super classe) and DrawClass.java



And my command line command is a follow:

D:\DOCUME~1\MAS TERPOINT\My Documents\Cours \Java\Pers
Teach\Prope_Obj \myPackage>set CLASSPATH=.;D:\ DOCUME~1\MASTER POINT\My
Documents\Cours \Java\Pers Teach\Prope_Obj \myPackage;



DrawaRect.java: 10: cannot resolve symbol

symbol : class firstClass

location: class figure.DrawaCla ss

public class DrawaClass extends firstClass

^

DrawaRect.java: 70: cannot resolve symbol

symbol : variable width

location: class myPackage.Drawa Class

02 errors

Abdelhalim,

The problem is that you are including the name of the package in the
CLASSPATH. The javac and java programs will append the package name to
the CLASSPATH entries. So what you want is:

D:\DOCUME~1\MAS TERPOINT\My Documents\Cours \Java\Pers
Teach\Prope_Obj \myPackage>set CLASSPATH=D:\DO CUME~1\MASTERPO INT\My
Documents\Cours \Java\Pers Teach\Prope_Obj ;

HTH,
Ray

Re: java CLASSPATH Environement var

ok, it's working, so as i understand the classpath var should always be set
to the directory containing the package directory itself!
thank's
