Re: [Classpathx-discuss] Re: Exception in IMAPBodyPart

[Cedric Hyppolite]

Hi Chris,

You were right, it happened again:

I got an exception in the code:
                if (pkey.equals(section))
                  {
                    System.out.println("Code class " + code.get(i 
+1).getClass());
                    content = (byte[]) code.get(i + 1);
                  }
                else
                  {
                    throw new MessagingException("Unexpected section  
number: " +
                                                  pkey);
                  }


Because the cast occurs on a String whereas it expects a byte[]

The API calls look like this:
Multipart multiPart = (Multipart)message.getContent();                          
for (int j = 0 ; j <  multiPart.getCount() ; j++) {
        Part part = multiPart.getBodyPart(j);
        MimeBodyPart mimeBodyPart = (MimeBodyPart)part;
}
mimeBodyPart.getContent() // Exception

The log is as follows:

Code class class java.lang.String

I'll send you the TCP dumps directly.

The message generating the error is  
address@hidden 
t with title 'MIME Message5 1146588060926'

Good luck,
