Hi,
I devoloped E-mail application.
I am running the application fine. But i am getting runtime exception as :

java.lang.NoClassDefFoundError: javax/mail/Message
<<no stack trace available>>
com.sssw.rt.util.AgoException:
java.lang.NoClassDefFoundError: javax/mail/Message
<<no stack trace available>>

You are getting an Error java.lang.NoClassDefFoundException

This means your OS (Operating System) is unable to find the class. You need to instruct a compiler to check the current directory where you have your generated class file.

For this, you can include . (dot) in your classpath like this.

Right click MyComputer Go to properties / Advance / In CLASSPATH include .;
(dot)

or
set classpath=.;C:\j2sdk\bin;

this dot will help compiler to check for the present directory for class.
try again java (your class) at command prompt.

You will get output now.

Web containers pay no attention whatsoever to the classpath. You need to put the jar file somewhere where the container will add the file to its own classpath. Check the documentation for your container.
