MarvinView Applet and JRE problem

Most of our users have JRE 1.4.2_14 installed, but the MarvinView applet does not seem to work for them. It works for those of us who have installed JRE 1.6.0_02 (via download directly from Sun). I believe all of our users still have Microsoft's JVM installed, but the Sun JRE is set as their default. The MS JVM will be physically removed later this year. Is it possible that the MarvinView applet is detecting the MS JVM and trying to use it instead of the JRE?





Here is an example of the applet:


<applet name="SamMarvinMolecule" code="JMView" archive="marvin/jmarvin.jar" width="250" height="250">


<param name="mol" value="...mol-string-here..." />


<applet/>

Does writing applet code with marvin.js work for you or not?

Code:

mview_name="SamMarvinMolecule" mview_begin(".",250,250); mview_param("mol","...mol-string-here..."); mview_end();
