java help

[blondielegs]

okay i want to install the latest version of java. version 6 update 10 and it says go into the terminal and enter su then the root password. i finally figured out how to do that. so now what is the next command cause i cant seem to figure it out.

[taurus]

Applications -> Accessories -> Terminal

sudo apt-get update
sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-plugin

When you get a java licensing screen, just press Tab to highlight the <OK> at the bottom and hit Return to accept it.

[blondielegs]

thank you but now it says its the latest version and its set to manually install and that i need to remove the old ones

[taurus]

So you don't want the version in the repos; instead, you want to install it manually. What's the name of the file that you've download and where did you save it on your computer?

[blondielegs]

im not sure which one i needed so i got both. and they are saved to the desktop. one is jre-6u10-linux-i586-rpm.bin and the other is jre-6u10-linux-i586.bin

[blondielegs]

if it helps i got it from java.com. i was getting it to play games on iwon.com.

[taurus]

You want the jre-6u10-linux-i586.bin since the other version is for rpm distros. The best way is to move it to /opt and unpack it from there.


cd ~/Desktop
sudo mv jre-6u10-linux-i586.bin /opt
cd /opt
sudo ./jre-6u10-linux-i586.bin
Now, you need to configure your machine to use the new java version.


sudo update-alternatives --config java
You should see the new version on the list and make sure you make it is the default one.


java -version

[blondielegs]

it keeps saying bash: cd: /desktop: no such file or directory everytime i try to enter cd ~/desktop
so now what am i doing wrong?

[blondielegs]

is there anyway for you to get into my computer and show me how to do it?

[madsmeg]

Capital "D" so

cd /home/username/Desktop

You should always ensure you have the correct case for the folder/file you are working with

[blondielegs]

still not working. and i used a capitol D. what now?

[taurus]

Don't forget the ~ in front.


cd ~/Desktop

[blondielegs]

i did that and it says bash: cd: /root/Desktop: no such file or directory
is it possible im in the wrong thing
im in [root@dani-desktop:~#

[taurus]

Why are you logged in as root? When you downloaded those two files, were you logged in as root also or with your regular account?

What's the output of this command from a terminal now?


ls -la

[gandaran]

are you running a ubuntu version that is not english? cd to 'Desktop' only works for english versions!

[blondielegs]

cause the directions said to loggin with my root password and i dont know what those commands were for that you just gave me. how do i get out of root. and yes i have been in it the whole time

[blondielegs]

im pretty sure it is english i live in nevada

[blondielegs]

that ls -la thing brought up this:
total 48

[blondielegs]

okay im not signed into root anymore. and the cd ~/Desktop thing worked. now what

[taurus]

Now do the steps in my post #7.

[blondielegs]

only the first one then this is what i did and its response.
dani@dani-desktop:~/Desktop$ sudo mv jre-6u10-linux-i586.bin /opt
mv: cannot stat `jre-6u10-linux-i586.bin': No such file or directory

[jgoguen]

Can you give the output of "ls -l" again?

you don't have to move it to /opt! what for?
you just run the install from desktop! just make sure you spell the correct file name

I thought you said you downloaded both versions!



im not sure which one i needed so i got both. and they are saved to the desktop. one is jre-6u10-linux-i586-rpm.bin and the other is jre-6u10-linux-i586.bin


You need to go back and download the jre-6u10-linux-i586.bin and then try those commands again.

[blondielegs]

i did i ran it again and this is what it said.

i have no idea what any of this means. and i tried your instructions again and it still doesnt work.

[blondielegs]

i just did what taurus told me i have no idea what im doing. i dont understand any of these commands. i came over from windows. and still havent figured this ubuntu thing out yet.

[taurus]

you don't have to move it to /opt! what for?
you just run the install from desktop! just make sure you spell the correct file name

Yes, you can just unpack it in your $HOME directory and run it from there BUT what if you have other users on your machine and you want them to use the new java version. However, you don't want people to browse your $HOME so you set the permissions to 700 to lock them all out. Then, they won't be able to use java version in your $HOME then.

So, there is a right way (logical way) to do things in Unix/Linux and there is a half-@$$ way to accomplish the same task. It's up to you which method you want to employ. If you feel comfortable with your method, use it.

[blondielegs]

i am the only user and is it usually this hard?

[blondielegs]

okay i was in the opt command and typed in ls -la and it said this:

[Elfy]

If you are getting errors please post what they say.

No it's not usually this hard :)

[jgoguen]

It's actually usually quite simple. But I have to ask, is there a reason you have to install this version, or would it be OK to install from repositories? The repository method doesn't require anything special, can be done from command-line or a graphical application, and gets automatically updated when necessary.

[blondielegs]

i did exactly what they said. and nothing is working. where am i going wrong?

[Elfy]

You need to follow taurus post #7 from here, you've moved the files so if you try again it will fail.

cd /opt
sudo ./jre-6u10-linux-i586.bin

and then do the rest

[blondielegs]

nope I don't agree! installing the file from desktop with sudo will install java in root file system (and i believe it won't be able to install anywhere else) where all users can use it and this is the correct way of installing things in linux

[blondielegs]

okay i went back to the instructions and i put this into the terminal:
chmod a+x jre-6u10-linux-i586.bin
and then i put the other command that you guys kept telling me to put in and it worked!!!
thank you guys.
