I want to get file extention from file's content-type.
I wanted to handle file with blank name in my mail client.
For handling this I need to create temporary file. For that I need to
decide file extention based on content-type.

getFileNameMap(..) function of UrlConnection constructs FileNameMap but
FileNameMap has method just to fetch content type from file extetion. I
want exactly opposite of this i.e File extention from Content-Type.

Sorry, but this doesn't make much sense. You talk about e-mail (which would be POP3, IMAP, SMTP or similar), then you talk about a file, but then you also talk about URLConnection (which would mean HTTP). So what is it from what you want to get some content type information? And what content type? I would guess we are talking MIME types here, aren't we?

If it is e-mail, then JavaMail has the means to extract MIME parts from a mail and provide you with the MIME types of the parts. If it is a file you probably want the JavaBeans Activation Framework (JAF) alone. If it is HTTP and URLConnection is not enough, you might want to look into Apache/Jakarta/Commons.
