Default CentOS, Firefox, and Java Plugin

The latest updates to CentOS 5.5 seem to have broken the Java plugin, and have defeated any and all attempts to get it working again. I'm running CentOS 5.5 (32-bit) and Firefox 3.6.9 (installed from the CentOS repository); I've tried BOTH the openJDK plugin available through the Argeo repositories, and installing Java 1.6.0 directly from Sun/Oracle and creating the plugin soft link in /usr/lib/mozilla/plugins. Neither works at all. This was working a while ago, but it broke and I didn't notice.

Thanks for any help you can provide,
-G.

Starting in Firefox 3.6.7 (I think) the (Sun) Java plugin changed names.
Here is what it should look like ...

$ ls -la /usr/lib/mozilla/plugins/libnpjp2.so
lrwxrwxrwx 1 root root 37 Jun 24 19:32
/usr/lib/mozilla/plugins/libnpjp2.so -> /usr/java/latest/lib/i386/libnpjp2.so

The plugin name changed .. the old one plugin is still in the jdk, but
will silently fail in the browser.

Hope this helps.

Barry

Funny I ahve: amd64 java "Sun" FF 64bit
libnpjp2.so -> /usr/java/jre1.6.0_21/lib/amd64/libnpjp2.so

and it does not work period. Sun says 64bit plugin works? All my 32
bit workstations are fine.

I only have 32-bit, which is what my example is from.

> epository); I've tried BOTH the openJDK plugin available through the Argeo repositories, and installing Java

I am the packager of the Argeo version of the JDK containing the plugin.

Please first note that the location has changed because some other
packages in the repo started to be used more widely and I wanted to
clearly separate Java efforts:
http://www.argeo.org/linux/argeo-el/5/java-plus/

Please also note that it will probably change location again (we are
upgrading our infrastructure) or even disappear if there is little
interested (I did not think that anybody else used it).
I recommend interested users to download the SRPM as a backup, in
order to be independent of future evolutions.

Now to your problem:
- the plugin is still working for me, and went smoothly through the
CentOS 5.5 update (from a package update perspective).
- but it is working badly: at some point it starts eating all the CPU
and I need to restart Firefox, or even kill the process
- the bug for x86_64 has been updated in July and they recommend to
try again with the standard version:
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=405

Did you try removing and installing the Argeo OpenJdk again?

I haven't looked at it yet, but my idea was to try again building the
plugin and if it works, to have an additional package only for the
plugin, which would not require to update the base OpenJdk (I had
rebuilt everything at the time because I also needed 1.6.0-b16 because
of some bugs fixed between b09 and b16, not only the plugin).#

If there is interest that I keep this effort public, please let me
know (off- or on-list).
This will give me a motivation to look at it sooner.

I realize that I should have been more precise (and read the OP more
carefully): the plugin from the Argeo repo is working for me on
x86_64, but I haven't tested it for a while on i386.

So it is indeed possible that the Argeo RPM plugin is broken on 32 bit
(this is a completely different plugin which is built between i386 and
x86_64 since the main plugin was broken on 64 bits)

I'll let it know on the list when (if) I find time to work on this again.
(interested users/testers/packagers are welcome to show up)

As per
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=405
the old default plugin (which is the one built for 32 bits in Argeo's
RPMs) is not supported anymore.

The NPP plugin is now the supported version which may explain why the
64bits is still working (more or less) and the 32 bits would be
broken.

So maybe a simple rebuild based on the existing specs files and using
the NPP plugin for 32 bits as well could already give at least basic
support (as in 64bits).
Using the latest version maybe a bit harder and require more analysis.
I'll let you know.

Thanks to everyone for their help. It turns out that I had two problems:
1) The page that you get redirected to by the Firefox plugin finder links
to these (incorrect) install instructions:
http://java.com/en/download/help/linux_install.xml#rpm
The correct install instructions can be found at Oracle's website:
http://www.oracle.com/technetwork/java/javase/install-linux-rpm-137089.html
2) I was using the Argeo-Plus plugin (32-bit), which appears to be broken.
Mathieu, if you get it working again, I'd be happy to use it, but if not, I understand.
I was aware that the location had changed (serendipitously), and have the latest
version (I've since rolled everything to the Oracle/Sun plugin).

Thanks all,
-G.

CCing the CentOS group on this... maybe someone there knows how to
handle the error.

Sorry to not answer this part in my previous email. I wanted to search
around to see if I could get the answer for myself... and it hasn't been
easy.

Apparently I don't have the java plugin browser installed. I've tried
to install it using the rpm.bin file at
<http://java.com/en/download/linux_manual.jsp?locale=en&host=java.com>,
but it's erroring out: "/bin/sh: bad interpreter: Text file busy".

I've never seen that error before.
