Hi,

I am facing an issue, where applet is not loading in FF3 and JRE version >= JRE 1.6.0_10.

Same applet is working fine in IE7 with same JRE. On using FF3 with JRE < JRE 1.6.0_10, it is also working fine.

Error on Java Console:
java.lang.ClassNotFoundException: xyz.class
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

[where xyz is name of an applet]

On navigating through various sites, finally i found on disabling the next generation plug-in, applet loads perfectly in FF3 also.
Windows Control Panel --> Java -->Advanced tab --> Java Plug-in --> uncheck Enable the next-generation and then restarting FF3, applet loads perfectly with out any error.

But what i want is :
can we do some changes in applet code so that it can load properly in FF3 rather than changing Java Plugin property?

Waiting for your reply.

Regards,
Vishal Razdan

Recently, Java and FF had some problems working well together - I had the same problem with FF not loading the applet and IE. Updating to JRE update 12 fixed it.
 
It is sorta covered in the JavaRanch Style Guide.
