(sun) java installation

[slwx]

hi,
Recently I've removed all default java and tried to install sun java 6, jdk and jre.

java -version
java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) Server VM (build 14.1-b02, mixed mode)

but I dont seem to be able to run java aplications anymore! The most important beeing netbeans.

I've tried this:
export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.15/
but it doesnt work, and honestly, i dont know what it does..

Anyone have an idea? I'm new to ubuntu, so sory if its a dumb question :)

thx

hi

- go to https://help.ubuntu.com/community/Java and see the Choosing the default Java to use bit , you need to update your alternatives .

- you may need to reinstall the progarms that use java , I know for open office you need to install are package open office-java or on the lines of that


hope it helps

ps for more see http://www.cyberciti.biz/faq/howto-ubuntu-linux-install-configure-jdk-jre/

You dont have authorization? You're not root? you may have to contact your administrator.

hi


-update 15 is out of date but its in ubuntu repos, could do with fixing that some time .

- what you need java?. if its just for everyday internet, openofffice use the openjava , as it says at http://sites.google.com/site/easylinuxtipsproject/java#TOC-OpenJDK-and-the-Icedtea-Plugin-are- the main java is been regularly moved about & removed .:KS 0r just do by the main website ...............

hi,
the extra info provided by coolcaseley67 (on the website http://www.cyberciti.biz/faq/howto-u...igure-jdk-jre/)
tell me:
"You also need to edit a file called /etc/jvm. This file defines the default system JVM search order. Each JVM should list their JAVA_HOME compatible directory in this file. The default system JVM is the first one available from top to bottom. Open /etc/jvm
$ sudo vi /etc/jvm"

-> but i have no file /etc/jvm
when i go to the folder and try to make one, i get "no authorisation" error..

i dont know how to go in root to make the file, im new!
thx

Hello,
to be complete, this is the original problem i had:
http://forums.netbeans.org/post-72261.html (http://forums.netbeans.org/post-72261.html)
its not really relevant, but maybe you want to know.
I was told to install the sun java instead of the default.
this is what i did, step by step:

removing via s/w centre:
OpenJDK java 6 runtime
OpenJDK java 6 webstart

removing via apt:
openjdk-6-jdk
default-jdk
openjdk-6-jre-headless

Then I installed Sun Java:
via apt:
sun-java6-jdk
sun-java6-jre

via s/w centre:
sun-java6-plugin

and finaly
sudo update-alternatives --config java


at this point java sun still didnt work. so i followed the instructions given by you here (http://www.cyberciti.biz/faq/howto-ubuntu-linux-install-configure-jdk-jre/)

*at first i didnt have a file at "/etc/jvm" , (this is what i posted on above, i didnt know how to make a file :s)
but now i found my way, i made a file at /etc/jvm/ with this in it:
/usr/lib/jvm/java-6-sun
/usr/lib/jvm/java-gcj
/usr/lib/jvm/ia32-java-1.5.0-sun
/usr/lib/jvm/java-1.5.0-sun
/usr

like the instructions tell me

finally i made a file
$HOME/.bash_profile

and in it, ther is:

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin



ok, now i have followed evry instruction, still netbeans doenst start, neither do any java applications (e.g. on internet).

thx

Hi
-I've just tried it MANUALLY and it worked and I verified online @ http://java.com/en/download/installed.jsp .

- i will check netbeans , i think you may need to go in to synaptic package manager and remove the programs and the con figs. then reinstall ..

hope it helps ](*,)

update
netbeans use the openjava ...... so you've remove it witch it needs to run ...

hi,
I have reinstalled java-sun-6 + downloaded netbeans manually from the website, and reinstalled it to. now it is working!
thanks for the help!
