i am new to predictionio and i am not able to install the predictionio on my PC. The steps given on the apache site i am not able to understand command like
$ tar zxvf apache-predictionio-0.12.1.tar.gz
$ gpg --verify apache-predictionio-0.12.1.tar.gz.asc apache-predictionio-0.12.1.tar.gz
.

.
which are given on site document
can you please provide step by step installation for windows.
The Prediction.io engine is meant to be installed in a Linux environment.
If you only have Windows available, you could download a VM manager, say Oracle's Virtual Box, setup a Linux distro, Ubuntu is fairly easy to use.
There's plenty of ressources online to do those steps.
Then follow along with the documentation of prediction.io, and it will work like a charm !
Or as #McMutton mentionned, a Docker installation documentation is also available.

I cannot install Java on Fedora.
I looked in the internet for tutorials and followed every of them and still no one of them helped.
If I try to do `java --version~ it says:
[root#fedora michael]# java
bash: java: command not found...
Install package 'java-11-openjdk-headless' to provide command 'java'? [N/y] y
* Waiting in queue... Failed to install packages: java-11-openjdk-headless-1:11.0.11.0.9-2.fc34.x86_64 is already installed
I don't know what to do, can someone help?
OK. I found solution: alternatives --config java
Try with:
sudo dnf install java-1.8.0-openjdk.x86_64
Enter the command:
dnf list --installed | grep -i java
And write what is displayed to you.

I'm on this for a really long time. I need to have JRE 6 running on a new nonactivated Windows server 2019 essentials to be able to use a very old remote controller for some servers (old IBM & DELL racks).
No matter what version of java I install, it's just not running. I don't see it in the bottom right corner or in the running services. I know it seems very basic but I couldn't find a solution online.
Am I missing something? All I could find online is suggestions to add java to the environment variables but that is for a different issue. I tried it desperately but of course it didn't solve the problem.
Java, or more precisely the Java Virtual Machine (JVM), is not something that runs in the background. JVM is used to start specific applications. How the java.exe or similar executable will be resolved and invoked will depend on the specific application.
What you usually see in the Windows task tray area is a the Java update checker (Jucheck.exe). Whether or not this service is present will depend on selected installation options. It also might be that a very old Java 6 simply does not ship it.

I am trying to launch JMeter through the BAT file on a windows machine but I am getting the following error:
Not able to find Java executable or version. Please check your Java installation.
errorlevel=2
Press any key to continue . . .
I have set the java path earlier and this was working perfectly fine earlier. can anyone suggest me how to fix this issue?
The message is telling you there is no Java in the path, which you can check by typing in a command line:
java -version
So you need to install JDK 8 or 11 , you can choose Oracle JDK or Open JDK.
Also check you use last JMeter version which is 5.0

I was working for a testing team, where we will be testing the application End-to-End. Every time before I test I have to install the java of different version and need to uninstall the same. We tried to do this using AutoIt but we failed to Automate the installation and un-installation part of java. I hear that we can install the java through command prompt, but not sure how to do it.
I use Window greater version with different flavors of java.
Can any one help how to Install & Un-install java through command prompt, which can reduce some of the manual efforts...!
Thanks in advance.
In order to install java silently you can simply make a batch file(.bat) with the following command
javaSetup.exe /s ADDLOCAL="ToolsFeature,SourceFeature,PublicjreFeature" INSTALLDIR=C:\Java\x86\ javaVersion /INSTALLDIRPUBJRE=C:\Java\x86\ jreVersion
A proper example for above skeleton will be
Here JDK 1.8.60 (x86) with source code is going to C:\Java\x86\jdk1.8.0_60 and JRE to C:\Java\x86\jre1.8.0_60:
jdk-8u60-windows-i586.exe /s ADDLOCAL="ToolsFeature,SourceFeature,PublicjreFeature" INSTALLDIR=C:\Java\x86\jdk1.8.0_60 /INSTALLDIRPUBJRE=C:\Java\x86\jre1.8.0_60
Just make sure you keep the batch file in the same directory as your setup file

I 'm use to work with Netbeans 7.2.1 on ubuntu 12.04.
Since the update on july 24, it's no more possible to create projects with it. That comes from the update of the openjdk, as mentionned on this topic.
The more convenient solution seems to use oracle-java instead of open-jdk. Hopefully, there are plenty of docs explaining how to switch from one to the other.
Nevertheless, I encounter an issue while trying to install oracle-java7 on my ubuntu.
In a terminal I type in sudo apt-get install oracle-java7-installer
Up to there, everything is going well, but then, the connection to edelivery.oracle.com fails because timeout expires
I'm behind a company proxy, so I assume the problem may come from that. But I'have no clue how to resolve that.
I have Linux Mint, I don't like relying on apt to have Oracle Java, so I did this:
Download the JDK from the Oracle website.
Unpack it in /opt/jdk_17
Create a link from /opt/jdk to /opt/jdk_17 (so every time I update the JDK I just need to update the link)
Add JAVA_HOME=/opt/jdk in /etc/environment
Update (or add) PATH to include /opt/jdk/bin
