Java EE (Java Enterprise Edition) General Discussion

Hi.

I have a JSP uploader. This works fine on Windows platforms. The linux version works well too, but only with text files. Any other file (.gpeg, .odt, .pdf etc) get corrupted in some way or another on uploading.

Kindly look at the code involved and help me out. Thanks.
