Firefox 3.6 can not incorporate with current Java-Plugin

Hi:


I wrap the marvin sketch applet within a hidden div (style="display: none;"), in firefox, after the page has been loaded for a couple of seconds, an alert is thrown:


Firefox 3.6 can not incorporate with current Java-Plugin.
Probably it is an old Java version, update to a newer one

However, if I change the visilibity of that div by js just before the alert, no exception is thrown.


Moreover, everything's fine in IE8.


Marvin version: 5.3.4
Firefox: 3.6.3
Java:1.6.0_20


Help?

We have built-in a warning mechanism in our code to try to avoid launching applet in those cases where Java Plugin is not supported by the current browser.


After users' feadbacks, we have realized that this bugfix causes false alarm in extreme situations.


Your bug report fits to this issue.


Because of aboves, we are creating a hotfix release where current solution is replaced to a more stable and effective solution.


This hotfix release (5.3.5) will be available very soon, in a couple of days.

This problems still exists in 5.3.5, do you mean a hotfix based on that version?

Are you sure that marvin.js has been refreshed in your browser cache?


If applet behaves like earlier, it means still the old marvin.js generates the applet code.


If the new marvin.js is loaded, the applet or a highlighted warning message is embedded into the web page.


The warning message can be the following:


The applet cannot run, because Firefox 3.6 is only supported with 
"next generation Java plug-in versions JRE 1.6.0_10 or higher.

or


The applet cannot run because your java plug-in is not available.

Open marvin.js in your browser to be ensure that its proper version is used. The first couple of lines of marvin.js should look like this:


//
// Inserted the content of http://java.sun.com/js/deployJava.js />//

var deployJava={debug:null,firefoxJavaVersion:null,myInterval:null,preInstallJREList:null,returnPage:null,brand:null,locale:

My fault, forgot to change a small parameter in my application, which leads to the same error.


marvin.js works now, thanks

A student is reporting a similar error, and we are using Marvin 5.4.0:


an error appears on ACE when I try to access MarvinSketch through Firefox. The error states: 



The applet cannot run, because Firefox 3.6 is only supported with next generation Java plug-in versions JRE 1.6.0_10 or higher.

Do I need to update Firefox, Java, or both? I didn't want to update Java without your opinion because I do not want to mess up ACE on Safari. Do you know how to fix this?

Do you know how to fix this?

Which Java version is installed to your student machine?


As the error message says, new Firefox can not incorporate with  old Java versions.


If it is earlier than 1.6.0_10, there are two options:
