In the following task, an exception may be thrown when you invoke the Transport.more() method.

1. Import the required classes and interfaces.

   import net.rim.blackberry.api.mail.BodyPart;
   import net.rim.blackberry.api.mail.TextBodyPart;
   import net.rim.blackberry.api.mail.Transport;
   import net.rim.device.api.ui.component.Dialog;
   

2. Create a method that takes a TextBodyPart object as a parameter.

   void readEmailBody(TextBodyPart tbp);

3. Cast the value that TextBodyPart.getContent() returns as a String to get the plain text part of the body of the message.

   _plainTextMessage = (String)tbp.getContent();

4. Invoke TextBodyPart.hasMore() and TextBodyPart.moreRequestSent() to identify if more of the TextBodyPart object is available on the server.

   if (tbp.hasMore() && !tbp.moreRequestSent())
   {

5. If more data is available for the TextBodyPart object, invoke Transport.more() to retrieve the rest of the TextBodyPart object.

   Transport.more((BodyPart)tbp, true);
   

private void readEmailBody(TextBodyPart tbp)
{
   _plainTextMessage = (String)tbp.getContent();

   if (tbp.hasMore() && !tbp.moreRequestSent())
   {
      try
      {
         Transport.more((BodyPart)tbp, true);
      }
      catch (Exception ex)
      {
         Dialog.alert("Exception: " + ex.toString());
      }
   }
}
