It shouldn't be necessary, but in this particular case it seems it is.

Odd. No error when you created the link? Then this should really be enough to get things working.

It still doesnt work.. What do you think the problem might be? I followed all of your proposed steps.

Could (remnants of) a previously installed Java plugin be interfering? What kind of Java installation did you have before (if any)?
Do any of the following terminal commands produce any output?
Code: Select all
locate javaplugin
update-alternatives --query firefox-javaplugin.so
update-alternatives --query mozilla-javaplugin.so

I guess I had the OpenJDK from the package that comes with the package manager. I had a problem with an applet and on a desktop Im running this java plugin and the applet works so thats why I'm trying to install it here. This is the output I get when running youre commands:
Code: Select all
simon@simon-HP-630-Notebook-PC ~ $ locate javaplugin
/opt/java/64/jre1.7.0_05/lib/i386/libjavaplugin_jni.so
/opt/java/64/jre1.7.0_05/lib/i386/libjavaplugin_nscp.so
/opt/java/64/jre1.7.0_05/lib/i386/libjavaplugin_nscp_gcc29.so
/opt/java/64/jre1.7.0_05/lib/i386/libjavaplugin_oji.so
/opt/java/64/jre1.7.0_05/plugin/i386/ns7/libjavaplugin_oji.so
/usr/lib/ure/lib/sunjavaplugin.so
simon@simon-HP-630-Notebook-PC ~ $
simon@simon-HP-630-Notebook-PC ~ $ update-alternatives --query firefox-javaplugin.so
update-alternatives: error: no alternatives for firefox-javaplugin.so.
simon@simon-HP-630-Notebook-PC ~ $
simon@simon-HP-630-Notebook-PC ~ $ update-alternatives --query mozilla-javaplugin.so
update-alternatives: error: no alternatives for mozilla-javaplugin.so.

Thanks!

There's definitely something odd here:
Code: Select all
/opt/java/64/jre1.7.0_05/lib/i386/libjavaplugin_jni.so
...etc.
That looks like a 32 bit Java in a 64 bit location. Does the symlink in ~/.mozilla/plugins actually exist? What does it point to?
I think you would probably be better off if you deleted the whole /opt/java/64 structure, downloaded a new tarball (make sure it's the 64 bit one!), removed the symlink in ~/.mozilla/plugins (never mind, the script should do that, I think) and ran the script again.

Great explanation!
One tiny little thing. I am running Peppermint 1, and when I right click the tar.gz file and told it to "extract here" it did not. I needed to doubleclick it, and open up archive manager, and use it to extract. I think this is an issue with peppermint, not your instructions. I used leafpad to read the scrip file, and pretty much understood it (I know my way around a C: prompt, but need a cheat sheet to do common Linux commands)
Just wanted to thank you for your great tutorial/script

Thank you! I'm a beginner at BASH scripting really, but that script was of "okay" difficulty (just mv, rm, cp, and ln commands).
Also, Pjotr's tutorial was my inspiration for making it (and partly my laziness at manually installing Java at every update LOL
).

Oracle Java 7 is vulnerable. Java 6 is safer and OpenJDK Java is safe, because IcedTea plugin does not allow the malicious code.
http://forums.linuxmint.com/viewtopic.php?f=58&t=111226
Code execution was confirmed with the latest Oracle and IBM Java 7 web browser plugin. IcedTea-Web using OpenJDK7 blocks this exploit by not allowing applet to change the SecurityManager (which is allowed in Oracle and IBM Java plugin).
Java 6 is currently not known to be affected.

Edit 1.9.2012
Oracle has fixed the problem publishing Java 7u7 ..
Edit 3.9.2012
Fixed an still broken ..

Downloading JRE 6 u 31 lol. Also gonna have to add a wee bit of bash code; I'll mark the codebox as "work in progress" for now and take the link off.

Are you sure that's a good idea? The most recent update of version 6 is 34.
