Mailing attachments; java.io.IOException; must be caught or declared to be

Question

I seem to be having trouble setting up to attach a file and I'm getting the error message
java.io.IOException; must be caught or declared to be
//other related code
    String bookingFilename = "what ever filename";
// create some properties and get the default Session
     Properties props = new Properties();
     props.put("mail.smtp.host", host);
     Session session = Session.getInstance(props, null);
     //session.setDebug(debug);
     try {
         // create a message
         MimeMessage msg = new MimeMessage(session);
         msg.setFrom(new InternetAddress(from));
         InternetAddress[] address = {new InternetAddress(to)};
         msg.setRecipients(Message.RecipientType.TO, address);
         msg.setSubject(subject);
         msg.setSentDate(new Date());
         // create and fill the first message part
         MimeBodyPart mbp1 = new MimeBodyPart();
         mbp1.setText(msgText1);
         // create and fill the second message part
         MimeBodyPart mbp2 = new MimeBodyPart();
            //PROBLEM LINE
            mbp2.setFilename(bookingFilename);
         // create the Multipart and its parts to it
         Multipart mp = new MimeMultipart();
         mp.addBodyPart(mbp1);
         mp.addBodyPart(mbp2);
         // add the Multipart to the message
         msg.setContent(mp);
         // send the message
         Transport.send(msg);
     } catch (MessagingException mex) {
         mex.printStackTrace();
         Exception ex = null;
         if ((ex = mex.getNextException()) != null) {
          ex.printStackTrace();the following is the problem code
mbp2.setFilename(bookingFilename);am I putting the filename in the wrong format?
I'm hoping to specify the exact filename using "if" statements so the current
String bookingFilename = "what ever filename";is just a placeholder
I'd be very grateful for any assitance
eventually I intend to email out 3 seperate attachments at the same time,
from a bank of about 10 files which are either pdf's or word doc's

Lets not go into my lack of Java training just yet :-P
     } catch (IOException ioex) {
         ioex.printStackTrace();was the block I was missing
I'd also miswritten the problem code...cos I'd been fiddling with other commands
mbp2.attachFile(bookingFilename);well it appears to compile... now to fire off a test email!
cheers
