I'm trying to rescrit a file being Upload based on FileContentType. I'm facing browser compatability issue. Suppose if i have to allow only jar files (application/java-archive) but i'm getting different contentTypes for different browsers. Like x-zip compressed, application-octstream for the jar fileContentType. So, i tried allowed extension types (jar) it's working fine. But the if user changed the extension of a text file [.txt to .jar]. It will fail and it's foolproof. How can i fix this problem?
ocjp 6 — Feeding a person with food is a great thing in this world. Feeding the same person by transferring the knowledge is far more better thing. The reason is the amount of satisfaction which we get through food is of only one minute or two. But the satisfaction which we can get through the knowledge is of life long.
