All,
Again, thanks to Otis for answering my previous question. I have another
issue...
I am attempting to create a simple exercise for our first year chemistry
students to create a page that displays molecule with JSmol. I have created a
pared down page from the test2 page and I give part of it below. I'm attempting
to restrict the exercise to using only HTM5/JavaScript and not touching Java
and I thought I had removed all reference to Java. The file works fine on my
own computer (in Firefox and IE and now in Chrome with Otis' workaround) but
when I attempt to open it on the computers available to students I get an
'Application Error' alert saying 'ClassNotFoundException' that appears to refer
to JmolApplet.class. The JSmol window seems to do something as it's black
whenthe page is loading but then shows a pale grey outline with a file icon and
red exclamation mark in the top right hand corner of the JSmol window. I'm not
entirely sure what differences there are between my computer and those
available to students but it seems there is something significant. I am
confused as I thought I had stripped out any reference to Java so what have I
done wrong?
As ever, many thanks for any pointers as to what's going on, and I appreciate
this may be a bit of an open ended question with the unknowns regarding what
applications are available.
