See nothing when running Java Applets

: My problem is: When I use Netscape to access Java Applets (like on web
: page, I see nothing
: being displayed on the applet window, but when I move the mouse into
: the window, Netscape's bottom bar showed "Applet running...".

Use the IP address of the host instead.  There's a Netscape bug that
prevents systems behind a firewall to view applets.

Another option it to use Internet Explorer....


See nothing when running Java Applets

: Thanks for the Cladera hype, but I seriously doubt that the problem has
: anything to do with the linux operating system since he's running the netscape
: from Win95.  The reason there are some many more complaints about slackware
: is because so many more people are using it.....
: Ming - Since you're running Netscape from windows, I don't think I can help you.
: I installed Netscape3.0b5 on my linux box last night and java works fine,
: although you MUST follow the README instructions for the java stuff to work
: right.

Thanks for all the suggestions. I actually installed Netscape Atlas on
my Linux box and the Java applets work well on Linux.

But my problem is I can't see anything (even with reload or refresh) on
my Win95 machine running Netscape 3/IE 3 connect to the Internet via the
Linux box (acts as a proxy server, running CERN proxy or Squid 1.0.5). I
can see the Java applets only if I connect my Win95 machine directly to my
ISP using a modem link.

Anyone recommend me a good proxy software for Linux other than CERN,
Squid, Apache and Harvest?



1. problem running Java Applets on linux - threads: cannot find class java/lang/Thread ????

I have a problem running Java Applets.
I'm running a SuSE7.2 based machine.

When accessing a page that has a simple "Hello World!" Java Applet
on it, the Konqueror window stays "Loading Applet".
When accessing the same page from another machne, it runs fine.

So... conclusion: the Applet is fine?

So now what is wrong?
I already checked some things.

In the browser, Settings->KonquerorBrowser->Java
I Do have: "Enable Java Globally" enabled,
I have Path to java executable to 'java'
And have not specified any Domain specific stuff

The 'java' points to:


This is a version 1.1.8:

java version "1.1.8"

So, IMHO, it seems that I DO have a working java. Don't I?

I also tried a different java, under: :/usr/lib/jdk1.3/jre/bin/java

java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)

But with similar results.

I tried starting Konqueror from the commandline, to see if it
complains.... Well it does, a little.
kdecore (KProtocolManager): ERROR: Protocol  not found
Unable to initialize threads: cannot find class java/lang/Thread
kjas: ERROR: could not parse length out of:
kjas: ERROR: could not parse length out of:

BUT, I can not really understand what would be wrong.
It seems that the 'threads' error might be the clue....

Anyone who has a suggestion here?

Btw, I also tried Netscape's Java, but with similar restults.
