How to set CLASSPATH for Javamail

[yihan]

Hello,
I added mail.jar and activation.jar into CLASSPATH. When compiling a java
file, e.g msgsend.java, successful, and generate msgsend.class. But when
excecuting msgsend, failed. It shows:
Exception in thread "main" java.lang.NoClassDefFoundError:
javax/mail/Message
I do as following:
in java compile file, add mail.jar and activation.jar into classpath:
@echo off
set
CLASSPATH=d:\;D:\Java\Javamail\javamail-1.3.2\mail.jar;D:\Java\Javamail\jaf-1.0.2\activation.jar
set PATH=%PATH%;C:\j2sdk1.4.1_02\bin
javac %1
pause

Can anybody tell me how to set CLASSPATH? Thank you.
