Java EE (Java Enterprise Edition) General Discussion

Hi guys. I am attempting to allow a user to download or open a file in their browser via a servlet. I can successfully do this, providing the user has configured their browser image to viewer - so they can choose "Open" to view in the browser window, or "Save As" to save it locally.

**PROBLEM** The file (no matter what file is selected for download) - is given the name of the servlet instead of the actual file name, therefore when the windows file browser prompts for save, the file is named whatever I named the servlet. I am only dealing with .TIF images, so for example a server file named F01222.TIF can be saved, but locally it appears as viewfax.TIF, where viewfax is the name of my servlet.

Here is my code, any suggestions are appreciated. Thanks.
