Android :: Sending Email With Apache Commons

I am trying a simple send mail application using apache commons library.

Here is the code.

The email sending code is working fine in a standalone application.However when I try to run it as android application

It gave following error message. trouble processing "javax/naming/AuthenticationException.class": [2009-09-17 05:33:20 - Commons]

Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message. [2009-09-17 05:33:20 - Commons] 1 error; aborting [2009-09-17 05:33:20 - Commons] Conversion to Dalvik format failed with error 1

I have added mail.jar,commons jars and jndi.jar to the references of eclipse If anybody know a resolution let me know.
