Msg.addRecipient(Message.RecipientType.TO,to) - won't compile in program

Question

I have had success in one of my servlets using JavaMail. I was able to send an email to my inbox to test it out. I proceeded to create another servlet based on that 1st one, and for reasons I can't explain, the servlet won't compile.
I get this error.
cannot resolve symbol :
         variable : RecipientType
         location : java.lang.String
                       msg.setRecipient(Message.RecipientType.TO, to); I get the same error when I switch out setRecipient for addRecipient.
However, through further testing, I've found that not only does my 1st servlet still compile, but I'm also able to run the code from the 2nd servlet, successfully in a JSP page. This is driving me nuts...how could there be a problem compiling? There's no reason why one servlet compiles (with similar if not almost exactly the same code) and the other won't. Plus this runs fine in a JSP page...what's going on??? I've spent hours on this and I can't figure it out...please help, any input is appreciated.
Here is the JSP page that runs successfully :
