How to install Java Virtual Machine for Mozilla?

JockVSJock · 05-10-2005, 01:53 PM

Running the almighty Slackware w/Mozilla 1.7.7 and I'm trying to get JVM up and running so I can check and send email via a web based Lotus Notes that has java.

-I'm putting the jvm under .mozilla/plugins

-Turn it into ./ by chmod u+x

-Then ./the bin file...

What else do I need to do to get it working ok. It still isn't showing up in the plugins.

thanks

You need to first install the java runtime and then create a symbolic link for libjavaplugin_oji.so into your Mozilla plugins directory.

There are detailed instructions on how to do this on my linux tips page, scroll down to a little below the middle of the page.
I wrote this some time ago and I was using I don't remember what version of RH back then but the jre install is quite similar on every distro.

Install it somewhere else and make a symbolic link pointing at jre1.5.*/plugin/i386/ns7/libjavaplugin_oji.so from ~/.mozilla/plugins

For some reason under my /home/.mozilla/plugins, I can't delete this directory:

jre1.5.0_02

It has the following directory

.systemPrefs

And it won't let me delete it.

Other than that I've create a directory in my home directory call .java and then have created soft links that link to the plugins directory under .mozilla but they still are not working.

***bump***

Still not getting the results that I need here, any ideas or help would be great.

thanks

You haven't said whether you've tried creating a symbolic link in ~/.mozilla/plugins pointing to the libjavaplugin_oji.so supplied with your java runtime environment. That's the way to go.

libjavaplugin_oji.so is in /home/.mozilla/plugins, why would I have to create a softlink for it?

Because it is not supposed to be in the plugin directory. From Mozilla.

Java Runtime Environment
1. Install Java Runtime Environment.
2. Make a symbolic link to libjavaplugin_oji.so in your Mozilla Plugins directory. Unless you are using an old version of Mozilla, or one you compiled yourself with gcc 2.9x, use the copy located in the plugin/i386/ns7 directory of JRE 5.0, or plugin/i386/ns610-gcc32 if you are using JRE 1.4.2.

"Do not copy the plugin to your plugs directory. If you do, Mozilla will crash any time you attempt to view a page containing a Java applet. " http://plugindoc.mozdev.org/linux.html

"On Linux, Mozilla requires JRE 1.4.2 or later.
Mozilla 1.4 and later, and Mozilla Firefox, are compiled with gcc 3.x. A gcc 3.x compatible version of the Java plugin must be used. JRE 1.4.2 and later contain a compatible plugin.

If you installed the JRE 5.0 RPM, this plugin is /usr/java/j2re1.5.0/plugin/i386/ns7/libjavaplugin_oji.so - and to install it for Mozilla (including Mozilla Firefox), do the following:

* Open a terminal
* Change to your Mozilla (or Mozilla Firefox) plugins directory
* Issue the following command: ln -s /usr/java/j2re1.5.0/plugin/i386/ns7/libjavaplugin_oji.so

Important! If you install your JRE in a different way (self extracting package, debian package, etc), libjavaplugin_oji.so will quite likely be in a different location. Do not just blindly use the command listed above!

Note: In JRE 1.4.2, this file was in plugin/i386/ns610-gcc32

Important! Always make a symbolic link, as shown above, instead of copying the plugin. If you copy the plugin, your browser will crash every time you open a page containing a Java applet. You have been warned!

If you are using an older Linux distribution, you may need to install the gcc3 support libraries, as the gcc 3.2 version of the Java plugin requires libgcc_s.so.1 to operate. You may be able to find packages using Google.

If you are using an old or unofficial build of Mozilla (1.4a or later) or Mozilla Firefox, you can check which compiler was used by entering about:buildconfig in the location bar and pressing enter. You will see a line such as "gcc version 3.3.2", which will show the compiler that was used. If gcc2.9x was used, you need to use the ns7-gcc29 or ns610 plugin, not the ns7 or ns610-gcc32 plugin."

Ok, I think I really messed up this time...

I've got alot of junk under /.mozilla/plugins...and I'm not sure what I need to keep and get rid of

Code:

ls -a

.
..
classic
client
flashplayer.xpt
green_threads
hotspot
install_flash_player_7_linux.tar
jre1.5.0_02
libJdbcOdbc.so
libagent.so
libawt.so
libcmm.so
libdcpr.so
libdt_socket.so
libflashplayer.so
libfontmanager.so
libhprof.so
libioser12.so
libjava.so
libjavaplugin_jni.so
libjavaplugin_oji.so
libjawt.so
libjcov.so
libjdwp.so
libjpeg.so
libjsound.so
libmlib_image.so
libnet.so
libpreemptive_close.so
libverify.so
libzip.so
native_threads
server

Do I only want to get rid of the .so files and then create the softlinks to this directory? I want to ask this question before I screw it up further...

thanks

If it helps I only have two files in my .mozilla/plugins directory.
nphelix.xpt
nphelix.so

The plugins that I have installed for Firefox are listed in /usr/lib/mozilla-firefox/plugins
Plugins (7):
* Helix DNA Plugin: RealPlayer G2 Plug-In Compatible
* DjVuLibre-3.5.14
* QuickTime Plug-in 6.0, Windows Media Player Plugin are supported by mplayerplug-in
* Shockwave Flash
* MozPlugger 1.7.1
* Adobe Reader 7.0
* Java(TM) Plug-in 1.4.2_06-b03

My java plugin is in /usr/lib/j2re1.4-sun/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

None of this probably helps. I have never had to create symlinks. apt-get install seems to do it automatically.

JockVSJock · 05-26-2005, 11:16 AM

When trying to create the following softlink, I get the following error:

ln './libjavaplugin_oji.so': File exist

I only have the following under /.mozilla/plugins

flashplayer.xpt
libflashplayer.so
