Very pleased to report that we should have no problem with file:// based
loading of Jmol and JSpecView java applets. In fact, now you don't need a
browser to open them, either. The solution was to provide "Java Network
Launch Protocols" in the directory containing the JAR files and to
reference that with a jnlp-href attribute in the applet's object tag.
Simple as that! Here is the Oracle developer forum answer that gave me the
clue: https://forums.oracle.com/message/11256775#11256775
I must say, my hat is off to these guys. Java applets still rock. Hope to
have files people can test tomorrow.
