Trying to make a higscore chart for applet

Question

hey im trying to make an highscore applet for a mathquiz applet and i need it to save the users score possibly as a cookie ryte now i am using:
PrintWriter out
= new PrintWriter (new BufferedWriter (new FileWriter ("file.txt")));
But this only works on the HSA console, Also if anyone knows how to make an exit button exit the internet explorer that would help to. Thanks alot

Answer 1

Sorry Sabre. Just trying to be a little realistic is
all.I fealt you were a little too dogmatic and negative about the problems the OP might encounter.

Setting aside the server-side (servlet) problems,
here are two questions I have about saving the high
scores as a cookie
1. (How) are you going to save the cookie? Normally,
web browsers receive cookie updates and store them
automatically. But since you'll be connecting through
java, that won't happen. If that doesn't happen, how
does the client know (aside from kludging the applet)
what cookie to send along with its request?This link shows exactly how to do it (without the need for WebServer involvement).

2. A year or so ago I spent a good deal of time
trying to fix up URLs and URLConnections so that I
could save and return cookies, since this is not
default functionality. I found that it was EXTREMELY
difficult to both extract the cookie and to add it to
the request. Perhaps you or others have had better
luck with this.
Right. Applets don't commonly allow you accessto
the
local file system. You can either report thescores
to the server (assuming you can put a servletthere)
or you can sign your jar file.
You're never going to get this to work either.Why won't the OP get this to work either? One can
easily self sign an Applet jar file and then allthe
user has to do is to agree to allow the Applet to
write the file!Again, sorry. My thought was that the work involved
in learning and implementing either the servlet or
local file system solution is going to take at least
as much time as everything else combined. It is true
that my experience with jarsigner and self-created
certicates is limited, but the times I have gone
through the process, it's just taken me forever.When the signing process is understood this is easy - even doing it manually. If one understand how to use Apache Ant then this is trivial to automate. If you would like to see a sample Ant script then I will post one (actually I use two scripts).
