User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1 Red Hat/1.0.1-1.4.3

Every time a java dependent web page is accessed, the little plug-in character
appears, and I am directed to install the missing plug-in. The problem is that
java is already installed. I have contacted the Redhat people, and they believe
the difficulty is that the current version of Mozilla does not have the ability
to work well with the 64-bit (AMD opteron) version of java under Linux.

Reproducible: Always

Steps to Reproduce:
1. went to a java enabled web page
2. tried to run the java app (or just look at one that should have loaded
automatically
3. got the "you need to download the missing plug-in" message

Actual Results:  
see above

Expected Results:  
given that java is already installed and enabled, the applet should run

The system is a dual AMD opteron 250 stand alone workstation running Red Hat
Enterprise Linux WS Version 4

Do you symlinked the plugin to the Mozilla plugin directory ?
Do you see  the plugin in "about:plugins" ?

which version of Java is installed? SUN just released JRE 1.5.0_02 Update 2

Installed the _02 latest release and linked the plugin directory to it - no
effect, and the plugin never shows up in firefox....

ccing roc, since this sounds like a 64-bit problem....

I have never been able to get java to work on my system either.  I just
downloaded the latest version, rm all of the previous installations as per the
Sun directions, intalled the jre in the /usr/java directory, went to the firefox
directory - /usr/lib/firefox-1.0.3/plugins and created a symbolic link.  Java
appears in correctly in the control center, but is not in the about:plugins in
Firefox.

I don't know if this is pertinent, but the default plugin is installed but
disabled.  I cannot find where to enable it.

I have Fedora core 3 running on a 2.8 ghz Athlon (32 bit) with Fedora core 3 and
the latest updates.  gcc343 is also installed.

When I try to go to http://www.java.com - the browser crashes.

I have the latest version of Java running as well.

I'm having similar problems with JRE 1.5.05 and Seamonkey 1.5a on Fedora Core. I installed the JRE with the RPM, and confirmed that I had a good link to the lib file.

If I try to view the Sun test page (http://www.java.com/en/download/help/testvm.xml)
I get the error message "This page cotntains information of a type (application/x-java-vm) that can be viewed only with the appropriate plug-in".  (Plug-in download goes to some netscape java page that is immediately redirected to "http://browser.netscape.com/ns8/").

I've spent a half an hour reading about linux java bugs without obtaining any clear understanding whether java is currently believed to work on linux.  Please opine if you have any current information on the matter.

See https://bugzilla.mozilla.org/show_bug.cgi?id=252659, which is about not getting the Java plug-in to work on Fedora...
