Bug Description

I have a java jar file, which is used by the HP RiLOE II remote console board. The applet is embedded into the web interface of the RiLOE like so:

<!-- Use jar based archive -->
document.writeln("<APPLET CODE = \"remcons.class\" ARCHIVE = \"remcons.jar\"");
document.writeln("width="+consoleWidth+" height="+consoleHeight+">");
document.writeln("<PARAM NAME = ARCHIVE VALUE = \"remcons.jar\" >");
document.writeln("<PARAM NAME=\"DUALCURSOR\" VALUE=\"false\">");

The applet only produces a gray square area, with so signs of any interactivity.

When the applet does work, using the official JDK, the applet displays a screen of my server, which I can use to remote control it.

Please note that on AMD64, I'm forced to using IcedTea as the official Sun JRE does not provide a web plugin!

Can you reproduce this in Hardy, using icedtea-gcjwebplugin ?

When using the beta live cd, and installing openjdk6 and icedtea-gcjwebplugin on it, firefox just totally freezes up.

So the applet does not just fail, it takes firefox down with it.

Also, other applets seem to freeze up firefox as well:

This is also broken for me, with intrepid. Is there anything one can do to aid debugging?

That PPA doesn't seem to contain a plugin for Firefox.

I've installed the openjdk-7-jdk package and the plugin definitely seems to be missing. I don't see any other packages starting with 'openjdk' that look like they might provide that. Trying to switch my alternatives to use openjdk-7 gives this error:

$ sudo update-java-alternatives -s java-7-openjdk
update-java-alternatives: plugin alternative does not exist: /usr/lib/jvm/java-7-openjdk/jre/lib/i386/IcedTeaPlugin.so

Searching further lead me to: http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=177

This bug was resolved as invalid. Bug 177 was caused by a certification issue. Here comes in the logic. When I connect to my compaq device, firefox starts complaining about the fact that the certificate can't be verified with any of its know CA's. So I have to force firefox to accept the certificate. What now think based on the link above is that icedtea is unable to fetch the java files from my compaq device because it does not accept the certificate of the device.

Do I now think in the right direction or am I way off here?

A workaround for an issue like this is provided here:
