Teh... you kinda got the right idea... but I think the question is wrong
thats why u getting no responses.
You cant get a servlet to call an applet....
but I have a feeling what you really asking is how to get a response from
the servlet.
This stuff you should find in a google so I'm going to let you do that
first... if you get stuck, I'll show you how to do it...
Search for how to POST to a servlet... google!
Can combine the search with HTTPClient or URLConnection.... you'll find lots
of articles
So wot you do is post a parameter that says.... fileToGet=MyGameFile.game
Then remember that just like a form... a servlet wants to respond... so in
the servlet you do something like this....
if the parameter is MyGameFile....... then......
File x = new File(PathToGameFile);
//So your applet knows when its got the whole file.... maybe you can send
this as a long instead and just read first first long as file length.
response.setContentLength((int)x.length());
OutputStream out = response.getOutputStream(); //Create a
stream
FileInputStream in = null;
try {
in = new FileInputStream(fileName);
int c; //Change this to a buffer if more speed
required... unlikely.
while ((c = in.read()) != -1) { out.write(c);}
} finally {
if (in != null) { in.close(); }
}
out.close();
Should get u going......

Subject: How to read file content from servlet?
Dear All,
I have an applet that sends data name, score and ScoreFile to a servlet
that get these data to be saved in a file. My question is, how can I send
these data from the servlet to the applet (reversed) so that I can use
only the data name in processing? Please help. Thank you.
Yours Sincerely;
TEH
The applet is as follows:
URL servletUrl = null;
URLConnection con;
String servletName = "http://localhost:8080/examples/servlet/ServerSide";;
try {
servletUrl = new
URL(servletName+"?name="+name+"&score="+score+"&ScoreFile="+ScoreFile);
con=servletUrl.openConnection();
con.setUseCaches(false);
BufferedReader buf = new BufferedReader(new
InputStreamReader(con.getInputStream())); }
catch(Exception e) {
System.out.println("Exception caught..."+e); }
The servlet is as follows:
String name = request.getParameter("name");
int score = Integer.parseInt(request.getParameter("score"));
String ScoreFile = request.getParameter("ScoreFile");
String fileName = "C:/temp/"+ScoreFile;
FileWriter resultsFile = new FileWriter(fileName,true);
PrintWriter toFile = new PrintWriter(resultsFile,true);
toFile.println(name+" "+score);
toFile.close();
