Hello,
even if getContentType() would return the 'correct' value (and it should
work - are you invoking ServletContext#getMimeType?), the user would still
be able to rename their zip files to .rar and pass your validation. What I'm
trying to say is that simply checking the extension does not really give you
any certainty that the user uploaded a rar file. There are a number of
libraries that examine file headers to find out their mime types. I don't
have experience with any, but I read about one on the server side recently (
http://www.theserverside.com/news/thread.tss?thread_id=53172).
Regards,
Levi
