Ok, thanks for you hints!
But I haven't understood two things:
1) How can I get a file using HTTPUrlConnection or HttpsURLConnection
classes? Which APIs must I use?
2) How can I read the file and send it to the user "on the fly"? When I
download the file before
sending it to the user I must store it somewhere....but where? Which type of
java variables must I use to store the file that I am downloading before
sending it to the user?
3) How to send the file to the user? I haven't understood very well what you
mean with "set the contenttype"...I need some more explanation...:-(
Can you give me some little piece of codes for example, please?
Thanks a lot!

Look at HTTPUrlConnection ( if using http ) or HttpsURLConnection. ( JSSE )
...
get the file .. and then set the contenttype ( and send it back to the
client on the fly ).....

Subject: How can I downlod a (pdf) file using a servlet?
Hello everybody!
I have problem: I have a web-site where there is a servlet running....let's
suppose the servlet name is "MyServlet". Some users can connect to the
web-site
and request to the servlet to download a .pdf file (but the file type is not
important and could be different). The file name is passed to the servlet
sending a parameter, for example connecting
to the url:
http://mydomain.com//MyServlet?FileName=File.pdf
Note that the requested file is on a different web-site (let's suppose
http://otherdomain.com)
and the servlet must connect to this other site and download the file
requested ("File.pdf") before sending it back to the user.
That I need to know is:
1)How can I download a file from another site using a servlet? I
mean....Which java code must
I add to my servlet to do this?
2)Before sending the file to the user who requested it must I save it on
disk or can I send
it to the user "on the fly"?
3)How can I send the file from the servlet to the user that requested it?
I hope someone can help me!
Thanks a lot in advance.
Luca
