HOWTO: Installing Java J2SDK | J2RE with firefox plugins

[Gandalf]

Hello,
i don't know if this solution has been discussed before, because it differ than the one available in http://ubuntuguide.org/#jre if yes i apologise for this

the purpose of this HOWTO: is how to install J2SDK or J2RE (i will consider you will install J2SDK in this HOWTO) with mozilla-firefox java plugin as debian packages, not directly from sources..

first you need to download J2SDK or J2RE from http://www.blackdown.org/java-linux/java-linux-d2.html

go to the folder where you downloaded the .bin file (j2sdk-1.4.2-01-linux-i586.bin in my case)


$ sudo apt-get install java-package fakeroot
$ fakeroot make-jpkg j2sdk-1.4.2-01-linux-i586.bin


you don't have to fill your mail and other info asked just press enter, when this finished you will find blackdown-j2sdk1.4_1.4.2+01_i386.deb in the same folder


$ sudo dpkg -i blackdown-j2sdk1.4_1.4.2+01_i386.deb


verify that java has been installed correctly as a java envirement and mozilla-firefox plugin,

java -version
to verify the envirement

in mozilla-firefox

about:plugins
you should see Java(TM) Plug-in Blackdown-1.4.2-01

Enjoy!!! :D

If that does not work, visit http://www.ubuntulinux.org/wiki/Java .

I have yet to test Blackdown; is it faster than Sun's own ?

the update java section is also there
*this is still the temp page

[dejitarob]

I would be careful running an old version of java. http://ubuntuguide.org/#jre links to the latest version (other binaries on Sun's Java download page (http://java.sun.com/j2se/1.5.0/download.jsp))

Careful ? why? as long as the application doesn't demand it, they should work [some old versions work faster than others... supposedly]. Even Limewire for Windows, downloads a very old java version, the one that works, not necessarily new. On old java's I have used azureus, limewire and websites like dslreports.

But, if a new version is available, there is no point in using an old one.

I tried to install the Sun J2SDK 1.5.0 update 2 using the method above, however it still didn't install the plugin.

After some research I found out that the firefox plugin is "installed" by creating a symbolic link to a symbolic link in the /etc/alternatives directory, which points to a non-existing file.

Whether or not this is because Sun changed the directory layout, or the make-jpkg doesn't set it up properly I am not sure, however by changing the symbolic link for
/etc/alternatives/firefox-javaplugin.so
from:

/usr/lib/j2sdk1.5-sun/plugin/i386/ns7/libjavaplugin_oji.so

to

/usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so

I've been able to get firefox to work.

I guess that by changing the mozilla-javaplugin.so and the netscape-javaplugin.so one will be able to get these programs to work properly as well..

Another way to solve this problem is to update the install file in /usr/share/java-package/sun-j2sdk1.5 by changing:

# assemble the plugin path
plugin_dir="$j2se_base/plugin/$arch_dir"

to:

# assemble the plugin path
plugin_dir="$j2se_base/jre/plugin/$arch_dir"

before building the package with make-jpkg.

Judging by the confirmations I am getting from running from terminal, I should be able to run java without crashing, right...? So far the best I get is the browser no longer crashes. I then decided to right click in the browser document of a page that contains an embedded applet, and View Page Info > Tab "Media"... There is no media content in the Media tab related to java. I doublecheck the page source to make sure there is an embedded applet and sure enough it is there. Please, any suggestions would be welcome so I can stop ](*,)

Edit: I tried symlinking with the "alternatives" directory. What change did I get? about:plugins no longer registers java as a plugin, BUT Firefox acknowledges applets in the Media "Tab" under View Page Info. Am I getting closer or further away? Hmm...

Mmm.. None of the applets I looked at showed up in my "Media" tab... However, they do run properly... and therefor I don't mind...

Looks like you lost the plugin... Just a question: how did you install your java?

[WMCoolmon]

Question: I installed Sun Java before I realized there was no firefox plugin for the AMD64...is it OK if I just install blackdown Java over it?

[Z-Bo]

@remkio

Thanks for replying. What do you mean "lost the plugin?" You are referring to libjavaplugin_oji.so correct? I have it...

One thing that might be screwing things up is all the installs and removals of Java I have done in the past week or so to get Java to work...

[dejitarob]

Question: I installed Sun Java before I realized there was no firefox plugin for the AMD64...There are AMD64 binaries on Sun's Java download page (http://java.sun.com/j2se/1.5.0/download.jsp) (click on 'Download JRE 5.0 Update 2'). Follow the install instructions in the unofficial guide (http://ubuntuguide.org/#jre), substituting i386 for your binaries of course.

[WMCoolmon]

That's exactly what I did; the problem is, there's no firefox/mozilla plugin for the versions on Sun's site. :|

[RastaMahata]

Thank you Thank you Thank you Thank you Thank you Thank you Thank you Thank you.
I finally have java in firefox (efter i don t know how many repositories added)... Someone should fix the wiki at ubuntulinux.org and state that those instructions are for warty! (/me hits his forehead):(

[dejitarob]

That's exactly what I did; the problem is, there's no firefox/mozilla plugin for the versions on Sun's site. :|That is why the ubuntu guide (http://ubuntuguide.org/#jre-mozilla) was linked.

I have succesfully installed java-package and fakeroot, but when i execute

I get this:

So it fails after entering full name, whether i leave it empty or write something to it.

Any help?
