Java applications don't get loaded
 
I am running Debian Squeeze, fully updated. I have installed java packages and created a symlink to libnpjp2.so

Both Iceweasel and Opera report that the plugin is installed. The correct version is reported. I can remove and re-install Java with the expected results.

When I enter a site with a Java applet, the applet is being downloaded, but fails to run. This is the message in the Java console:

Code:
load: class Foil.class not found.
java.lang.ClassNotFoundException: Foil.class
        at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
        at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)

        at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
        at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: Foil.class
This happens for every applet I try to execute.

I have different other machines with Debian Squeeze which run Java just fine. I have dpkg --get-selections on those machines, and made sure all those packages were installed on this problem machine, but to no avail. For the record, these are all java packages currently installed:

sun-java6-plugin                                install
tzdata-java                                        install
I have also tried to install openjdk and the java version from the Java website, with exactly the same results. All java versions, the Debian package, openjdk and the downloaded version from the Jave website run on other machines.

I hope the error messages make sense to someone.

Easy: the class cannot be found...try this: do a sys-wide find for foil.class, and either append that to your PATH system variable, or (my preferred option) make a symlink in one of the folders that is in the PATH (usually /ect or /bin) to the location of foil.class. You could just make a symlink to foil.class alone, but that may just be too narrow...

Good luck

No that can't be.
Foil.cl is the applet I download from the web site I am currently at.

So check on you own machine whether Foil.cl is present. It is not.
Then go to this site:
http://www.grc.nasa.gov/WWW/k-12/airplane/foil3.html
And see? Foil.cl is executed.

Now, even if Foil.cl is downloaded at the instant I enter that web site, and stored on my machine and executed, why does this mechanism not work on my problem machine?

Oww, you got me with my pants down...okay, so, the bottom line is that an applet cannot be executed. Let's see just what the applet needs...
I just tried is, and it ran (dunnow at all just WHAT happened, but, something did happen), I did do a thread dump, though. To see what gets loaded. I suggest to compare bot thread dumps...
Can the problem box run ANY applet at all?
Next, let's look at the browser. Could it be the thing wrongly codebase addresses the base address of Applets? Just a thought...let's compare browsers.

This IS interesting...food for thought.

Not any Java applet is being executed. Foilsim is just an example for which I know is working correctly on most of my computers. Any applet raises that ClassNotFound exception.

I wish I'd understand what exactly happens when the Java plugin is started. I assume the plugin has to know where the standard classes of Java can be found so everything can be build and loaded together before execution. And it seems somewhere goes wrong just there, but I see zero debugging possibilities.

What exactly do you mean with thread dump? Is that something I can produce?

I am using the latest Opera and Iceweasel (=Firefox) version 3.5.16

Yes, you can reproduce that, but the console has to be visible. Run jcontrol, usually found in /opt/java/jre - but your location could differ, select the lat tab and select to show the console...

Great pointer. But it doesn't make any sense to me. Does it to you?

Just a quick thought...is Debian Squeeze 64 bit? Just checking, because, this:

Quote:
Java HotSpot(TM) 64-Bit Server VM (2
caught my attention...according to the release notes, 64 bit is supported, is the hardware 64 bit? According to this

Quote:
(Linux 2.6.32-5-amd64)
it seems to be.

Furthermore, does the user (you, in fact) have execute rights on the plugin?

Wat does about : plugins (kill the spaces - the forum softwzare would make a smiley...) say? Type that in the address field...does the plugin appear in the list?

Yes, it is 64 bits.
I have 4 other machines running Debian Squeeze running 64 bits, they all perform correctly with Java. Of of them has 32-bits Java installed.
I also installed the 32 bits version on the problem machine, same result.

Thor
The plugin appears in the list in both Opera and Iceweasel. When I remove the Java installation they disappear. When I re-install Java, they re-appear.

IMHO the plugin is actually running. It tries to lead the requested class and then tells me it cannot. Is there some kind of inherent search path? I know for stand-alone applications you need a CLASSPATH. But that seems not to be needed on any of the other machines to launch a Java applet in the browser.

Just being utterly curious, what is the PATH variable like? Try to compare that with the well-behaved boxes...

It was so easy after all.... sigh

Don't know why I suddenly found the correct thread.

Thanks for your assistance. Especially the pointer to jcontrol was helpful.

No sweat! Glad I could help! :)
