[Jmol-users] Re: Jmol problem with Internet Explorer or with code

Charles,

I have taken the liberty to copy this message to the jmol-users mailing
list so that others may benefit from seeing the response.

People should post these types of questions to the jmol-users mailing
list. Then other members of the jmol community can help you, and everyone
can see the answers. (I have subscribed you to the list & you will receive
a notification message.)

Also, if list readers know the answer to a question then they should
answer it. Then I don't feel obliged to answer and I get to spend a little
bit more time coding :-)

This is a minor point but ... the JmolApplet does not require any special
configuration of the web server. This differs from Chime, where it was
necessary to configure mime-types. (I only point this out because plugins
and applets work differently, and at times this causes confusion. So I
think it helps to point out the differences.)

Looks good ... works for me on
 Mozilla Linux
AND
 WinXP/IE 6.0.2800.1106/+ Java Plug-in 1.4.2_03

Netscape 7 does not have a built-in Java Virtual Machine. Therefore, you
must have the Sun Java Plug-in installed.

I suspect that the issue is that you do not have the Java Plug-in
installed on some of your systems. Microsoft no longer ships a Java
Virtual Machine. It must be installed separately. Go to:

  http://www.java.com

and click on

 'Get It Now' in the upper right corner

In IE, if you click on Tools then you should see an entry called Sun Java
Console. If not, then it is not installed. Or, under Tools -> Internet
Options ... -> Advanced you sould be able to see an entry called Java
(Sun) which has the checkbox checked.

Good.

Hmmm ... this has the MSFT virtual machine ... but you can optionally
install the Sun Plug-in. You can control which one is used under Tools ->
Internet Options ... -> Advanced

On *all* of these Internet Explorers?

In which case, my theory of not having the Java Plug-in installed was
incorrect.

Hmmm...

You should get some output in the Java Console (Sun or MSFT)

No, file format cannot cause this type of compatibility problem.


I suggest that you pick 1 of these machines. Tell us which JVM you are
using, and tell us what you are seeing in the Java Console.
