How to Install Java on Linux Lite

[waynebob]

On both my LL 2.8 and LL 3.0 my installed Flash is Ver. 11.2.202.632.
Go to Adobe, select APT for Ubuntu and download now, get "the address wasn't understood, Firefox doesn’t know how to open this address, because one of the following protocols (apt) isn’t associated with any program or is not allowed in this context.
 You might need to install other software to open this address.

And in the Java Control Panel the enable Java content in the browser is enabled.
The Java version appears to be a Server VM.
linuxlite@linuxlite-H170-D3HP:~$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
linuxlite@linuxlite-H170-D3HP:~$ /usr/lib/jvm/oracle_jdk8/bin/jcontrol
linuxlite@linuxlite-H170-D3HP:~$ /usr/lib/jvm/oracle_jdk8/bin/jcontrol
linuxlite@linuxlite-H170-D3HP:~$

I'm not in front of my LL box..
But for the Flash you want the APT not Yum.. If I recall if once APT file is downloaded it install easily; similarly to how Synaptic does..

For enabling in the browser, I believe in the Java Control panel (see the path I listed in a previous thread) under Security there is a check box to enable in the browser...

Still don't have Java working in Chrome, Firefox or Chromium. Tried the Java website to enable FF and Chrome but didn't work.
Chrome no longer supports NPAPI (Java) and will no longer support Flash in September.
Chromium needs Flash update and Java is a no go.
Firefox needs Flash update (YUM or APT) and Java is a no go.
I was searching for a "best linux for Java and Flash" and downloaded Ubuntu Gamepack and PlayLinux thinking maybe they would be set up for online gaming. Still fooling around in Virtual Box, no luck yet.
Thanks for your help, Wayne.
P.S. I installed Teamviewer

Good to see you got it!!!!

The tar command will extract the compressed file..

Shortened explanation of the command tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1
tar -zxvf extracts the compressed jre file (more so any file starting with jre-); into the directory../oracle_jdk8 ..

Crap, reading this do I have to unzip the downloaded file first. I am in the downloads folder but the file is still compressed.
Unzipped the file and it now shows. Tried the next step and got a very long message that it did not work. Should I put it here, it is very long?
Maybe my previous missteps have borked the install.
Redid Jerry's instructions and it worked now. I didn't even think to unzip the downloaded file, rookie mistake.
Now just have to get it working in Firefox and Chromium.
I see Chrome is going to stop using Flash in September so more fun ahead. :-)

Here is what I have now, looks like it worked.linuxlite@linuxlite-H170-D3HP:~$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
linuxlite@linuxlite-H170-D3HP:~$

Given up LOL; naw you're almost there - just little things, no show stoppers...
Just to confirm, your version of Linux lite is also 64bit?

So the error says there's no jre file.. It needs the correct location - you can cd to the full path or
Open Thunar (file manager) to the location of the downloaded JRE file. If its in your downloads folder open download.
Then right click (a blank area) and I believe its open terminal from here - you want terminal to be pointing to your downloads..

If you open terminal and its at "~" (aka your home folder - /home/user) You can cd to Downloads,

Code: [Select]

cd Downloads
The above is the same as the command below - assuming your username is linuxlite

Code: [Select]

cd /home/linuxlite/Downloads
You can confirm you are in the correct directory by typing

Code: [Select]

lsThis will list the items of the directory (folder) you're currently in (Downloads in this case) you should see the jre file listed - if not cd to the correct directory..

Then you can run the tar command..

Code: [Select]

tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1
If you have already done the touch and leafpad commands those should be fine as is..
I would finish with the

Code: [Select]

source /etc/profile.d/oraclejdk.sh

 Good Morning, haven't given up on me yet eh? ;-) Yes I downloaded the 64 bit  that Jerry recommended. Here is what I get when running your script.
linuxlite@linuxlite-H170-D3HP:~$ tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1
tar (child): jre-*: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
linuxlite@linuxlite-H170-D3HP:~$

Well I sure am getting practice using the terminal. That is a good thing right.

[firenice03]

Is there any errors when running the script?

Code: [Select]

tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1
Something to confirm from the Java download page https://www.java.com/en/download/linux_manual.jsp

You downloaded the correct version for your OS?
- Java x64 for 64bit LL or Java for 32bit LL

This is what I show now.
linuxlite@linuxlite-H170-D3HP:~$ java -version
The program 'java' can be found in the following packages:
 * default-jre
 * gcj-5-jre-headless
 * openjdk-8-jre-headless
 * gcj-4.8-jre-headless
 * gcj-4.9-jre-headless
 * openjdk-9-jre-headless
Try: sudo apt install <selected package>
linuxlite@linuxlite-H170-D3HP:~$
I think this is a lost cause, the last instructions did not go perfectly.
Both Firefox and Chromium are complaining about Flash, Chrome is okay.
The Java for Perfect Pair Solitaire is still MIA. :-)
Tired and will look at this again in morning.
Thanks for your help, I am getting too old (67) for all this brain teasing.

Once java is installed..

Code: [Select]

java -version should show an output similar to this

dad@TRCD-LLMini:$ java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) Client VM (build 25.91-b14, mixed mode)

If you need the java control panel after its installed you can run the following in terminal..(it will open a GUI)

Code: [Select]

/usr/lib/jvm/oracle_jdk8/bin/jcontrol

[firenice03]

You're just about there - I've installed Oracle java this way several times I use it for work and once installed it works fine...
I don't use pogo - but have had to "support" it for some friends - Pogo uses a lot of flash.. I checked and was prompted to update my flash (adobe) - prompts for .tar.gz and apt... Don't use yum or rpm (other distro's)..

I'll look to see if I see anything in regards to flash here.. but I assume pretty straight forward
Flash is installed by default..

[firenice03]

OK so java isn't installed yet..

So I assume you've downloaded java and its in your download folder if so...
You can open terminal from here...

This will unzip/install

Code: [Select]

tar -zxvf jre-* -C /usr/lib/jvm/oracle_jdk8 --strip-components=1
Allow to run then

Code: [Select]

touch /etc/profile.d/oraclejdk.shCreates the file oraclejdk.sh

The next command will open the newly created file in a text editor (leafpad - similar to notepad)

Code: [Select]

leafpad /etc/profile.d/oraclejdk.sh
Leafpad will be blank - copy the next few lines into the document and save..
Its "coded" to ease selecting, just select and copy then paste into leafpad)

Code: [Select]

export J2SDKDIR=/usr/lib/jvm/oracle_jdk8
export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre
export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin
export JAVA_HOME=/usr/lib/jvm/oracle_jdk8
export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db
Once you have the above pasted and saved (file-save) you can close.
then in the terminal window

Code: [Select]

source /etc/profile.d/oraclejdk.sh

I even did both browser Java stuff on their website and neither browser shows the plugins or will work at Pogo for the wife's game. Crap.
