[SOLVED] Java Complications

[LngLvThKng1682]

I've installed Frostwire, but when I go to run the program I get this message:

Starting FrostWire...
Java exec found in PATH. Verifying...
OOPS, you don't seem to have a valid JRE. FrostWire works best with Sun JRE available at http://www.java.com
OOPS, unable to locate java exec in  /usr/lib/  hierarchy
You need to upgrade to JRE 1.5.x or newer from http://www.java.com
ls: cannot access /usr/java/j*: No such file or directory
OOPS, unable to locate java exec in  /usr/java/  hierarchy
You need to upgrade to JRE 1.5.x or newer from http://www.java.com
ls: cannot access /opt/j*: No such file or directory
OOPS, unable to locate java exec in  /opt/  hierarchy
You need to upgrade to JRE 1.5.x or newer from http://www.java.com

According to the Ubuntu Documents it said to run: sudo update-alternatives --config java
and choose the option with Sun in the name, but none of my alternatives have Sun.
Am I missing something or doing something wrong?
All help is appreciated.

Do you have the "universe" and "multiverse" repositories selected in your Software Sources? If not, do that and open up Synaptic then search for "sun." It should show the Sun version of Java in several packages (JREs and JDKs).

How do I get to my Software Sources?
Sorry..

Please forgive me for my last post, it's been one of those days.
I completely looked over Software Sources when I went into the Administration.
What you suggested did work. I enabled the multiverse and found the Sun updates in Synaptic.
Frostwire works fine now.
Thank you very much, and I again apologize.

No need to apologize. These things aren't always obvious, and even if they are it's easy to miss. I once spent half a day trying to diagnose a wireless network problem on a laptop only to realize that the killswitch on the front had been turned to OFF the whole time.
