File download servlet

[Rashmi Tambe]

I have written a servlet that downloads a file. The file is downloaded properly , however, wherever i click on a URL, the dialog box that pops up for download shows message as ,
DownloadServlet from 192.167.8.99
where DownloadServlet is the name of the servlet that gets called and then my ip address. how can i display string like
demo.txt from www.mywebsite.com[/B]
do i have to add some special headers ???or what ?
When i download the file , by default the filename is my servlet name. i need to rename it.
How can i download a file using its original name?
TIA
