Java Mail with POP3

[Cosmin Popa]

Can you explain me how to use java mail with pop3 support?

I have tryed:
///--------------------------------------------------------
   PrintWriter out;
        /// ...
    Session sess;
    Store stor;
    try 
    { 
     sess=Session.getDefaultInstance(System.getProperties(),null);
     stor=sess.getStore("pop3");
     stor.connect("mail.dnt.ro","user","xxx");
     stor.close();
    }
    catch (Exception e) 
     {
      out.println("Error :"+e.toString());
     }
    out.println("Done");
///-------------------------------------------------

And when I execute the servlet, next error apear:
javax.mail.NoSuchProviderException: No provider for pop3

I put the pop3 jar in the orion/lib and /orion ... but nothing.
