You mean
$(document).ready(function(){
$("#jmoldiv").html(Jmol.getAppletHtml("jmolApplet0", Info))
})
does not work?
If that's the case, then I think you have something subtle wrong with your
div styles. I'd like to see the page, if I could.

I'm guessing the problem is that you are trying to populate that div prior
to page completion, using Jmol.getApplet instead of Jmol.getAppletHtml.

Ah, yes. If that's the case, that that's significant, that would indeed be
the problem. Jmol is going to use:
var o = window[tokens[0]];
so if myMessageCallback is not the same as window.myMessageCallback, then
that will fail.
Interesting...

Yes, I see that looks inconsistent. Info.readyFunction is called by the
JavaScript on the page, thus the direct function reference. Jmol callbacks
are called from within the Java or JavaScript, so they have to be
transmitted as string names of functions.

I agree, but that's the way it is. Java itself cannot handle direct
JavaScript function objects as variables, I think.Those are being passed as
<param> tags to the <object>. So strings only.

I think you could do this:
Info.msgCallback = myMessageCallback
Info.messageCallback = "Info.msgCallback"
Just make sure
window.Info == Info
because Jmol is going to get that function as:
window["Info"]["msgCallback"]
