i've made a project, i want to test this code:

Code:
String cmdlocation = "c:\\program files\\Mozilla Firefox\\firefox.exe";
String gweb = cmdlocation
try {
Runtime.getRuntime().exec(gweb);
}
catch(IOException ioe){
System.out.println("Did not work");
}
and well, it works... but when i jar the file and add the jar to a html file, it doesnt work in the html file, but the jar file works opening with a batch file.

does anyone know how to fix that?
