I'm working with an applet that was not originally made by me, and that is used by a large number of users.
From my web server log files I can see that the applet sometimes looks for files based on the codebase of the applet which do not exist on the webserver and so cause a 404 error.
The files that are looked for are these:
For the first two of these I cannot find any pattern regarding what browsers and/or java versions are involved, but the second two only seem to happen on Apple computers (using Firefox or Safari).
The java code of the applet does not mention any of the files or class names as far as I can see. Googling the file names returns little.
Any ideas what the cause(s) can be?
