Completed Project Doesn't work When Deployed FilePermission Error

Question

Hello all,
I have been slaving away over an applet for the past several weeks, and I have finally gotten it finished. When I tried to upload it to MY web server, it suddenly stopped working. The applet itself reads files from the directory in which it is run, and apparently even when these files are given a 777 permission, the applet still can't read them. I'm baffled as to what's going on.
For the HTML code, I am using
<applet code="tempGraph.class" codebase="http://www.michaeljaylissner.com/archive/java/" height=400 width=750>Java Applet</applet>
The page hosting the applet is here: www.michaeljaylissner.com/pct-temperatures.
The code for the applet and the data files themselves are here:www.michaeljaylissner.com/archive/java/.
Any help would be greatly appreciated. I was so happy to have the coding done, I just assumed that putting the thing in a website would be easy. WRONG!!
The error the java console is giving me is: Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.io.FilePermission iButtonResults-MattChurch-2.csv read)
I can't imagine how to fix this problem!

Hmm, are you doing something like this to load the file?
        timingProps = new Properties();
        InputStream pis = this.getClass().getResourceAsStream("/timing.properties");
        if (pis != null) {
            try {
                timingProps.load(pis);
            catch (IOException x) {
                CCLogger.getLogger().log(Level.SEVERE, "Unable to load the timing.properties configuration file! " + x.getMessage());
            finally {
                try {
                    pis.close();
                catch (IOException x) {/* do nothing */}
            CCLogger.getLogger().log(Level.INFO, "Timing properties have been loaded.");
        } else {
            CCLogger.getLogger().log(Level.SEVERE, "Unable to load the timing.properties configuration file!");
        }I think you are right that you shouldn't have to sign the applet if the file is coming from the same web server the applet is deployed on.
