Using JavaME to get a file's MD5 checksum

I am trying to use J2ME to get the md5 checksum of a downloaded file.

I haven't been able to find anything that sh开发者_开发知识库ows how to get the md5 checksum of a file in J2ME, all I can find is in java's MessageDigest which I can't use.

It is not a "ready-to-go" solution for MD5 calculation against a file, but RIM's MD5Digest class should be able to get you what you need.
