Cast SharedByteArrayInputStream to Multipart

Question

I get this exception java.lang.ClassCastException: javax.mail.util.SharedByteArrayInputStream cannot be cast to javax.mail.Multipart, the error appears when i try this, I already do the conexion to the server POP3. Could anyone help me??
Thanks! Here is the code...
Message [] mensajes = folder.getMessages();
for (int i=0;i<mensajes.length;i++)
System.out.println("---------->From:"+mensajes.getFrom()[0].toString());
System.out.println("Subject:"+mensajes[i].getSubject());
System.out.println("Subject:"+mensajes[i].getSentDate());
// Si es compuesto, su MIME type es multipart
if (mensajes[i].isMimeType("multipart/*"))
// Obtenemos el contenido, que es de tipo MultiPart.
Multipart multi = null;
try{
//Object la = (Object)mensajes[i].getContent();
//Vector la = (Vector)mensajes[i].getContent();
//multi = (Multipart)la;
multi = (Multipart)mensajes[i].getContent();
}catch(ClassCastException cce){
System.out.println("nel" + cce);

So then don't cast it to Multipart. Use the instanceof operator to see if it's a Multipart before you try to cast it.
