Following Miguel's post: > To run locally without a web server (using file:///.......) you *must* put > *all* of your files in the same directory. This includes the > JmolApplet.jar file. So your [applet] tag must say > codebase="."
Things wll work in local mode if the applet is in the *same* folder, as Miguel points out, but also if the applet is *above* the molecule file in the file tree. (In the example cited, the applet was in a sibling folder with respect to the molecule, that's the cause of the error.) So, you can also have codebase=".." or even codebase="../.." I like to have several folders for my models and pages, so my solution is to put the applet file in the root of the site.
