Trouble installing Java - Unable to verify the security integrity

Let's say you get this error:

---------------------------
Error - Java(TM) Update
---------------------------
Unable to validate security integrity on the file. File is either corrupted or unsigned.
---------------------------
OK
---------------------------

And you go to www.java.com and do the "Free Java Download" ... installing it gets this:
---------------------------
Error - Java(TM) Installer
---------------------------
Downloaded File C:\Documents and Settings\username\Application Data\Sun\Java\jre1.6.0_17\jre1.6.0_17-pfrom15.msi is corrupt.
---------------------------
OK
---------------------------

What to do?
Go to the Manual Download section and download the Offline install (second link) (It should look similar to jre-6u17-windows-i586-s.exe)

If that doesn't work, drill down and find the jre .msi file and install that.

Installing Java 6 release 13 on ubuntu

For Firefox (sudo su):

mkdir java6
cd java6
wget http://ftp.mgts.by/ubuntu/pool/multiverse/s/sun-java6/sun-java6-plugin_6-13-1_i386.deb
wget http://ftp.mgts.by/ubuntu/pool/multiverse/s/sun-java6/sun-java6-jre_6-13-1_all.deb
wget http://ftp.mgts.by/ubuntu/pool/multiverse/s/sun-java6/sun-java6-bin_6-13-1_i386.deb
dpkg -i *.deb


Ubuntu!

OK, really quick:
1) The default java implementation ... stinks. Go to java.com and get a real implementation.
2) The multimedia answer is VLC. If I could sum up all the questions for how to watch DVDs, listen to streaming audio (like Live 365), etc., the answer is VLC. No, really. Yes, that DVD:/ error on totem. Install VLC. Use it. Enjoy.
3) All the cool Compiz goodness that you see on YouTube -- Wiggly windows, etc., are in System->Preferences->Appearance->Visual Effects and Extra. But you need to install the compizconfig-settings-manager and go back to there (Custom) and have fun
