Class Cast Exception

I am extracting the content from an email message. I am casting this into a string object. However, when it is a multipart message and it gets to the text/html content I get a class cast exception. Does anyone know what type of object is being returned since it is not a string.

I can't seem to find anything about it.

Below is the method:

private String extractContent(MimeMessage msg) throws MessagingException, IOException {
//extract content
StringBuffer sb = new StringBuffer(1000);

if (msg.getContentType().indexOf("text/plain") != -1) {
//plain text message
sb.append((String) msg.getContent());
} else if (msg.getContentType().indexOf("text/html") != -1) {
sb.append((String) msg.getContent());
} else if (msg.getContentType().indexOf("multipart") != -1) {
Multipart mp = (Multipart) msg.getContent();
for (int i = 0; i < mp.getCount(); i++) {
Part part = mp.getBodyPart(i);
if (part.getContentType().indexOf("text/plain") != -1) {
sb.append((String) part.getContent());
} else if (part.getContentType().indexOf("text/html") != -1) {
sb.append((String) part.getContent());
}catch(UnsupportedEncodingException e){

If you really wanna know you can do a

or something very similar to that basically you get the class and then it's name and you can tell exactly what you have.

Usually the detail message of the CCE will tell you. Not always though for some reason.
