Hi. My web host is Lunar Pages, and their operating system is UNIX (mine is Windows 7). On my localhost copy of my PHP/SQL website on my computer, I simply use PHP's exec() function to call "java ChatServer" and it runs. However, this does not work online. So I was wondering if there were any alternatives, or fixes to this. I have everything ready but this. So, any input would be really appreciated. Thank you in advance.
