download binary file

[Michael Reutter]

Hi!
 
my static page now loads an applet.
 
what I want is, that the applet's-jar file isn't physical a jar file, but a servlet's 
output.
I have several jar-files in a directory not in the web-path and the servlet should 
randomly give back one of these applets!
 
my questions:
what method to overwrite in HttpServlet
is Content-type: text/plan ok for a jar-file
and how to read the file and write it to the response object
 
thanks
michi
