View Full Version : [ubuntu] Sun Java

September 25th, 2008, 02:13 AM
I am using ubuntu desktop 8.04 fully updated as far as I know, and Firefox 3.02

A few days ago Sun released update 7 to java6. A couple of days later my yahoo mail and chat stopped working, have to go to classic mail, cannot get into my bigstring.com mail, google adwords disappeared from my webpage, several other things apparently also use java as they stopped working and disappeared.

Went to Sun java website to upgrade to update 7 as it has not appeared in a ubuntu as of yet.

Managed to download to desktop, came in as a dot Bin. After much trial and error, using terminal. got it to run and said it was done. sun jave 6 update 6 is usr/lib/jvm/, so is update 7. nothing works!!!

If I go to root terminal an enter java version, the following is what get:

root@OlerThanDirt-laptop:/home/fred# java version
Exception in thread "main" java.lang.NoClassDefFoundError: version
Caused by: java.lang.ClassNotFoundException: version
at java.net.URLClassLoader$1.run(URLClassLoader.java: 200)

at java.lang.ClassLoader.loadClass(ClassLoader.java:2 51)
at java.lang.ClassLoader.loadClassInternal(ClassLoade r.java:319)

So what should I do?? I did not put in smiley face!!! maybe it means something???

My thought is do and un-install for update 6 and 7,then re-install 7

Anybody got any ideas???

As per usual advance thank you cannot find star with blue ribbon!!! to use

You can try and see if you get the same behavior with different flavors of Java. To see how to change the default java in use, see the bottom of this page (https://help.ubuntu.com/community/Java).

I have SOLVED this one. In the SUN JRE for which ever update you are trying to get to run. Look in the BIN file, There is one called Control Panel, double click on it comes with a dialog box asking if you want to run in terminal, display, or run, picking the run option as root If you have done a launch pad for nautilus. allows you to set it up using a GUI

At least that is the way I remember it!!! Kicking 70 yrs CRS is pretty prevalent



CRS= Cannot remember stuff is the clean way. Sub Stuff with another S word :roll: this is an LOL

It should be
java -version - you are missing the minus sign.
