How to resolve Unhandled exception type javax.mail.MessagingException?

How do I resolvethe MessagingException error for the program below  and at next to the last line"postEmailObject.postMail(recipients, subject, message, from);" is where I get a squigley line depicting an error.  In the Consle the the error reads java.lang.Error: Unresolved compilation problem:
      Unhandled exception type javax.mail.MessagingException

      at java.lang.reflect.Constructor.newInstance(Native Method)
      at xxx.xxx.xxx.xxx.TestMail.main(TestMail.java:24)(line 24  is different here because I excluded the package statement.  
Exception in thread "main"

Have you the mail.jar and activation.jar included in the classpath? Both are required, assuming this is using the Javamail API behind your PostEmail class.
