It seems to load something but nothing shows up. I had assumed it would be as easy as that, but does this mean I have to install jsROOT on the server hosting the file?
Ok I figured this out on my own. “Installing jsROOT” is not difficult at all, just download the source code and copy the whole directory over to your webserver, then use the index.htm in the provided source instead of the gsi address.
I was relying on my browser providing a file listing when asked to show a directory without an index.html file present: uhhep.phys.uh.edu/~jcaron/ has no index file.
I guess somewhere the server generates such an index file but I’m not up to messing with the server configuration.
