Sorry, too complicated for me

I Give up! Thanks for you help anyway tho.

Matt

P.S. If anyone else can write a simple java applet that submits to the cgi script in my previous post, then please add to this thread. Thanks

Then you would need to figure out what the following variables do, as I assume that this line specifies what is sent to the script:

post = "final="+account+"&state=1&style=1&comments=";

I don't think that solution is going to work, because the java class was written specifically to interface with a guestbook file.

It has lines of code that watch out for spaces in the guestbook, then appends the information as one long string (I think)..

e.g.

code
--
if(line.endsWith("Comments:"))
--

I think the class needs changing so that it POSTs name, wisecrack and score to the cgi script.

Ok, then if the script your friend wrote will take the fields as already named, which I think it will (but I'm not used to his writing style), then all you need to do is edit the below line in the Java class:

      URL url = new URL(
         "http://www.geocities.com/"+"cgi-bin/geoplus_apps/ans_entry"
      );

Change that code to redirect to the location of his script...which should then work, once again going on the fact that his variables are named accordingly.

The java applet class (2nd listing) used to record scores in the Geocities guestbook. The Geocities guestbook cgi changed though, so I was no longer able to record scores in it by using the class.

Someone else has since written me a cgi script (1st listing) that works perfectly. However, I don't know how to alter the java applet to work with this new script.

Sorry If I wasn't clearer in the first place

Cheers
Matt

Ok, I see where it outputs to the CGI script...and I think I should be able to get that to work. But, what I don't get is that it seems to be reading from the questbook pages? I didn't get the impression it did that from your earilier post.

Anyways, I should be able to help you...I'll try to get something posted soon.

The old cgi script was part of a geocities guestbook - I don't know how to get a copy of the old or new version of that script unfortunately.

The high score program was a java applet class written to interface with the cgi of the guestbook.

Here is the Java code that interfaced with the old cgi script:

Is there anyway that you or anybody else could alter the code so that it interfaces with the cgi script in my previous post?

Thanks
Matt

Matt,

I have the slightest idea on how to programm Java. However, if the Java was already submitting to a script, and the script changed, I thought I could just recreate the script it used to submit to. But, does the Java program submit to a specific URL? Because if it does...then I'm not sure I can do anything.

Hopefully this works out.

richjb and nutrocker - thanks for the replies!

richjb - the variables i want recorded are name, wisecrack and score.

The Java Class should pass these variables to a cgi script. A friend of mine has already written a cgi script that does the job perfectly, but I don't know how to write the Java applet to pass the variables to the script.

I have attached a copy of the working cgi script if this helps, but to be honest i don't know if it would be easier for you to write the java applet class and re-write the cgi script too

Anyway, thank you once again for your help I will credit you in full on the site if you supply me with the details you would like displayed.

Cheers
Matt

Hello Matt, welcome to the Webmaster Forums.

Please specify the name of the variables you want recorded, and I will write the code for you.
