Re: [JAVA3D] Applet reading from file?

If u r trying to read the file from local system, then, no, u can't do it (unless u grant appropriate permissions like BOL said). But u can read anything via URL connection, for instance, from the webserver. So, if u need to read some .txt file with your applet's configuration in it, then u can do

I think if you just give the complete path to the earth.jpg file, it will work. This solution is only if you are running the applet locally in a browser. Otherwise you will probably have to make a URL, etc. to download textures, etc. remotely. "Kasparian, Raffi J." wrote: > Hello all, > > This i
