Dear jGuru ,

I am a newbie using Java.  
I do must of my number crunching programming in APL but I am working now
on an application, to be used in several places that require limiting access to
only your own data.   I figure out that
the best way was to provide for a password, to be emailed by the application to
the first time users, provided that the user is in the accepted database, to
his/her email address.  

The application worked fine, after some struggle (including
sending the e-mails) in my desktop, but when I moved to my portable for
testing, I am not able to send e-mails.   I
am running it on a Windows XP environment.  

The e-mail program is a quick adaptation of
class=SpellE>sendmail provided by Javamail as
a sample.   It requires including the following
libraries:

import java.util .*;

import java.io .*;

import javax.mail .*;

import javax.mail.internet .*;

import javax.activation .*

I have created a lib on the portable containing all the
files in the JDK library plus the activation jar of javamail .
style='mso-spacerun:yes'>  The contents of the library are:

Tools.jar

Activation.jar

Ct.sym

Dsb.jar

Dt.jar

Htmlconverter.jar

Imap.har

Ir.jar

Jawt.lib

Jconsole.jar

Jvm.lib

Mailapi.jar

Orb.idl

Pop3.jar

Smtp.jar

After some fudging with the path and CLASSPATH, the program starts
loading but stops providing the following message:

Exception in thread “main” java.lang.NoClassDefFoundError :
javax /mail / messagingException .

Java started loading the program and attached the first two libraries
in the list but can not find the third one.  
As a matter of fact, nor can I.
style='mso-spacerun:yes'>  I did a thorough search of the hard disk on
my desk top looking for javax *.* and I was able to
find a couple of empty directories and the few directories that contain files,
the files were only *.html files.

I presume that the fix is a trivial one, but I have not been
able how to do it.   Help will be
appreciated.
