Hi,

I could not find a JAVA related forum so I'm posting it here in hopes for an answer or this being redirected to correct forum.

I'm a newby to java programming and have the following problem. I have a java class that lives in a certain package a.b and also a mail.jar (JavaMail from sun) that leaves in another library package of the same project. I have imported the necessary files from mail.jar inside my java class file and have no compile errors there, however, when I run it I get the NoClassDefFound pointing at the jar file. Do i need to do anything else to tie them together?

thanks
