Recognization of content type?

Question

Hello everybody I've a little problem with javamail
I try to identify the type of the parts in a message, my code work well with a lot of mails but with some mails javamail can't recognize the type of some part.
so my code to recognize "text/html" and "text/plain" part is :
Part p;
if (p.isMimeType("text/html")) {....}
else if (p.isMimeType("text/plain")) {....}
But some message which contain part marked like this :
NextPart2434489_boundary
Content-Type: text/plain; charset:ISO-8859-1
or
NextPart2434489_boundary
Content-Type: text/html; charset:ISO-8859-1
cannot be recognized whereas if the message have part marked like this :
NextPart2434489_boundary
Content-Type: text/plain
charset:ISO-8859-1
or
NextPart2434489_boundary
Content-Type: text/html
charset:ISO-8859-1
My code recognize the text/html and the text/plain part! it's normal?
Should I parse the mail before trying to recognize part, to put it in the correct format, or there is another solution with javamail?
Help me please
Thank you very much and excuse me for my poor english.

I just started with javamail this morning, so I'm no expert. But maybe this will help you. I did my checks like this:
if (msg.getContentType().toUpperCase().startsWith("TEXT") ) {
...}which has worked on the dozen or so emails I've checked.
