[SOLVED] Missing Java on LM 18.2?

[richlion2]

Hello,

I am a bit lost here. I have one laptop with LM 18.2 which is an old installation (from 18.1) and has been constantly updated and upgraded. I have an application that is in Java and this is what I have installed:
java -fullversion
openjdk full version "1.8.0_131-8u131-b11-2ubuntu1.16.04.3-b11"

The application works.

On another computer on which I installed 18.2 directly from a new .ISO download it seems Java is not exactly there:

$ java -fullversion
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>

My first question, where is Java, is it not included in the 18.2 installation?

Second, how to install the proper version? I tried following this link:
https://www.2daygeek.com/install-java-o ... archlinux/#

Used:
sudo apt-get install openjdk-8-jdk

But Java is still not there.

Regards,
Richard

Hi "richlion2",

It would help to know more about your system setup. If you run "inxi -Fxzd" from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.

Which Java application is it?

Oracle Java and Open Java installation

The Java runtimes are probably available in the Software Manager or Synaptic Package Manager (SPM).

Install new Oracle Java 8 In Ubuntu, Linux Mint, with links to install previous versions (6,7).
http://www.webupd8.org/2012/09/install- ... a-ppa.html

To install this using the PPA method, open a console terminal, type in, or copy & paste, each line below one by one:

Code: Select all

sudo add-apt-repository ppa:webupd8team/java

Code: Select all

sudo apt-get update

Code: Select all

sudo apt-get install oracle-java8-installer

[/color]

For Java9

Code: Select all

sudo apt-get install oracle-java9-installer

[/color]

VIP: Switching between Oracle Java 8 and Java 9
Later on, if you want to switch Oracle Java 9, use the following command (make sure "oracle-java9-installer" package is installed):

Code: Select all

sudo update-java-alternatives -s java-9-oracle

[/color]

And, switch back to Oracle Java 8 using:

Code: Select all

sudo update-java-alternatives -s java-8-oracle

[/color]

If you get some warnings when running these two commands, ignore them.

VIP: Setting Java environment variables
To automatically set up the Java 8 environment variables, you can install the following package:
sudo apt-get install oracle-java8-set-default
-------------------------------------------------------------------------------------------------------------------------
OpenJDK Java 8 has been made into official Ubuntu repositories for 14.10 Utopic and higher.
For Ubuntu 14.04, Ubuntu 12.04, and Linux Mint 17 users here’s how to install it from PPA.
http://ubuntuhandbook.org/index.php/201 ... 12-04-lts/

Code: Select all

sudo add-apt-repository ppa:openjdk-r/ppa

Code: Select all

sudo apt-get update 

Code: Select all

sudo apt-get install openjdk-8-jdk

[/color]

VIP: If you have more than one Java versions installed on your system. Run the command below to set the default Java:

Code: Select all

sudo update-alternatives --config java

[/color]

Type in a number to select a Java version.
And set default Java Compiler by running:

Code: Select all

sudo update-alternatives --config javac

[/color]

4. Finally check out current Java version by running:

Code: Select all

java -version

It outputs something like this:

openjdk version "1.8.0_01-internal"
OpenJDK Runtime Environment (build 1.8.0_01-internal-b04)
OpenJDK 64-Bit Server VM (build 25.40-b08, mixed mode)

Hope this helps ...

I would love to use the Software Manager, but how do I find it?
First - programs/packages are not sorted by name and there are thousands of them.
Second - the search button has never worked, I type a text like "java" and press the search button and nothing happens.

I used your instructions and still no luck, here are the results (Sorry, Polish version):

The program I am using is for my Forex trading platform in Java downloaded from here:
https://www.oanda.com/forex-trading/pla ... e-platform

[richlion2]

Solved:

installed LM 18.1, performed ugrade to 18.2.

You can test it, go to
https://www.oanda.com/forex-trading/pla ... e-platform

scroll down to where the Download button is.

This will pull the file fxTrade_installer.tar, when you inpack it it's a file fxTrade_installer.sh.
Run the script, this will create a shortcut in your Desktop folder. You then try and launch it. If there is a problem, an error shows immediately.
if Java is installed then you will see the application launch as in the attachment.

Regards,
Richard

This worked for me on 6-16-18. Needed to install JRE to use LibreOffice macros. Thanks very much.
