Please help figure out an uncaught exception,

Question

Hello All,
I've setup javamail API package to use with Resin web server by copying the necessary jar files under WEB-INF/lib. I've copied mail.jar, mailapi.jar, pop3.jar, smtp.jar and activation.jar.
According to my readings I have everything I need to send simple messages out. But when I run my web application to send a simple message, I get FileNotFoundException exception, please see the snippet diagnostics below. Furthermore, I get an exception somewhere that does not seem to be one of the exceptions I'm catching. I cannot figure out what that exception is and where it's coming from.
I get a FileNotFoundException somewhere during the process of sending the message, but that doesn't seem to stop the process so I'm not sure if that has anything to do with the final uncaught exception.
By the way the email message is sent and does reach its destination in spite of the uncaught exception.
Does anyone have any idea what is happening and why?
Thanks in advance for any hints and tips.

In the debug output you showed there, the JavaMail code is looking for a resource that could be in several different places. It doesn't find it in the first place but then it finds it in the second place, so it doesn't have any problem with that. So it carries on to send the mail normally.
If your program is ending abnormally, you should get a stack trace with the uncaught exception at the top. If you can't find that, wrap your code in this:try {
  // your main routine goes here
} catch(Throwable t) {
  // output this exception somewhere you can find it
}
