JNLP file error

Question

Hello
I got some strange behavior in my program and I don't understand why. Here is the situation.
I have 2 jnlp files with the exact same content except one character.(the name of the file in the href below codebase). The first one is running perfectly fine and the second return me an error. Here are the 2 files (HelloFrame(running fine) and HelloFrame2(returning error))
The error message is : Il manque le champ obligatoire suivant dans le fichier de lancement : <jnlp>
which mean : There is missing an obligatory field in the launching file : <jnlp>
<?xml version="1.0" encoding="utf-8"?>

Ok I found a way to fix this problem but I don't like it. It's really stupid and I don't know why it would in anyway matter but it does. So if anyone could understand something of my following explication and tell me why it do it, I would be really gratefull.
Here is what cause the problem and what I did to solve it.
If I create a JNLP file and I don't upload it yet on my server (http://www.gudradain.byethost12.com/) and I try to run it from the folder in which I create it I will get an error message (which seems normal)
If I upload my JNLP file that I got an error message sometime before on my server and I then try to run it I still get an error message (which I don't understand why because the file is on the server now so it should be able to access it)
But if I create an exact copy of this file and I put it on the server and then test it (so I didn't get any error message before I test it) now it will work
What I realize is that if I ever get an error message with a JNLP file that mean my JNLP file is screw and will always return an error message even if I correct this error. WHY!!!???
