I am trying to install Oracle SOA Suite 12 on Windows 10. I set the JAVA_HOME correctly (able to echo it), and then trying to run the JAR. It gives me the following message:
This installer must be executed using a Java Development Kit (JDK)
but C:\Program Files\Java\jre1.8.0_161 is not a valid JDK Java Home.
It seems to look for the JRE folder and by default neglecting the JAVA_HOME environment variable. I did a workaround by navigating to the JDK folder, and then running the java.exe inside the JDK folder (java.exe -jar /path/to/soasuite). It works well. I just want to know what might be the reason.
I advise you to set the properties as follow. Adapt correctly to your path in the JAVA_HOME property, and the others will follow.
JAVA_HOME := C:\java\jdk1.8.0_151
JDK_HOME := %JAVA_HOME%
JRE_HOME := %JAVA_HOME%\jre
CLASSPATH := .;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
PATH := %JAVA_HOME%\bin;%PATH%
EDIT:

the java.exe inside the JDK folder (java.exe -jar /path/to/soasuite).

This means that you are missing the change in the PATH environment.
I was not able to utilize the path variables described - did not want to restart the machine durng and install of oracle software. I was able to successfully complete the install of weblogic oracle fusion by doing the following.
RUN JAR files using command prompt due to having issues running the java installed setups for oracle12c, weblogic ,etc.
RUN command prompt as adminsitrator:
1. CHANGE DIRECTORY IN COMMAND PROMPT TO:
C:\Program Files\Java\jdk1.8.0_181\bin
RUN the command like this - pointing to the proper JAR file.
java -jar c:\oracleformssoftware\fmw_12.2.1.3.0_infrastructure.jar
This definately worked for me but please note I did finally setup the path variables instructions noted here.
I am trying to install Apache Spark on my Windows 10 computer. My first step to install Spark was to download Java from here it was then downloaded through this path: C:\Program Files (x86)\Java the one folder that was downloaded during this installation was: \jre1.8.0_151
Next I installed the JDK from here and downloaded the windows x86 version. I used the same path as above in the Java folder to download it. After it was done I had two folders inside the Java folder: jdk1.8.0_151 and jre1.8.0_151
Afterwards, I set the JAVA_HOME variable to point to C:\PROGRA~1(x86)\Java\jdk1.8.0_151 and in Path I added %JAVA_HOME% I then installed Scala from here and downloaded the Scala binaries for Windows. The environment path was added in path as: C:\PROGRA~1(x86)\scala\bin
Next I installed Spark from here and installed spark-2.2.1-bin-hadoop2.7.tgz Afterwards, I placed this folder here D:\spark-2.2.1-bin-hadoop2.7I then added the environment variable as SPARK_HOME with the path: D:\spark-2.2.1-bin-hadoop2.7\bin and I then updated path to %SPARK_HOME%\bin
Finally I tried to see if everything was installed. I typed java -version and the correct java was installed. I then typed scala and scala was open for me to type in expressions and such. I then typed in spark-shell but I got this error:
'spark-shell' is not recognized as an internal or external command,
operable program or batch file.
What am I doing wrong that is not making spark open? Please note: I am using cmd for everything.
It looks like you set your %SPARK_HOME% to a wrong place and thus when "I then updated path to %SPARK_HOME%\bin" it resulted in adding D:\spark-2.2.1-bin-hadoop2.7\bin\bin with double \bin which is obviously wrong. %SPARK_HOME% should be without \bin.
Generally you can test your environment variables by calling echo %PATH% in the command line or SET to show all of them
Mac OSX 10.11.14 (El Capatin) does not ship with Java, either the complete development kit (JDK) or the run-time environment (JRE). My need was to just run a .jar file and not for complete Java development. So I downloaded the JRE from here, which is a much smaller file compared to JDK (quite obviously).
This SO answer says that JRE is enough to run jar files.
After installation of JRE I couldn't locate the directory where installation happened or run java command to execute files on my mac. How do I run jar files now?
To run java application you can either use
/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
or (as you found)
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
In any case, if you need to run java often, you should set JAVA_HOME in either your ~/.bash_profile or ~/.profile and amend the PATH to include the bin directory.
After JRE installation, the correct path is:
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin
But now, how do I run the java command? It seems like the java file located in the directory above is not an executable.
I installed a new JRE 1.7 on my Centos server.
However, when I type in java -version it shows the version 1.6, which means the hosting provider preinstalled that before?
How do I shift it over to the new one 1.7 I installed and make it permanent?
Thank you!
You need to set your PATH environment variable so that the bin/ directory from your Java installation precedes the system-wide ones. For example, in my user-specific ~/.bashrc configuration file for the Bash shell I currently have:
export PATH="/usr/java/latest/bin:$PATH"
Note that I prepend (rather than replace) the Java program path to the previous value of the PATH variable, so that other programs will keep working without requiring the use of absolute paths. As for /usr/java/latest, it is a symbolic link created by the RPM packages Oracle provides that points to the latest version of Oracle Java installed on my system.
For bash, edit the startup file (~/.bashrc):
PATH=/usr/local/jdk1.7.0/bin:
export PATH
For sh, edit the profile file (~/.profile):
PATH=/usr/local/jdk1.7.0/bin:
export PATH
Source: PATH and CLASSPATH
I installed openjdk-6-jdk on my ubuntu box using apt-get.
In system info jenkins is telling me Java.Home is /usr/lib/jvm/java-6-openjdk/jre
However when I specify that directory as JAVA_HOME in Jenkins : "configure system", it returns error message saying that directory does not look like a jdk directory.
it is also failing to pick up my maven install.
Am I missing something obvious ?
Your JAVA_HOME variable must be set to /usr/lib/jvm/java-6-openjdk and it must be available for the user that starts Jenkins.
From Kyle Strand comment:
As of April 2015 (I think), Jenkins requires Java7. Also note that the java binary path (JAVA) must be set to the correct version if the system default is still Java 6. Finally, for anyone wondering where these variables are set, it's in a config file listed with the installation instructions on the Jenkins webpage (e.g. for Debian it's /etc/default/jenkins).
Using Jenkins 2 (2.3.2 in my case), the right way seems to insert the following into your pipeline file:
env.JAVA_HOME="${tool 'jdk1.8.0_111'}"
env.PATH="${env.JAVA_HOME}/bin:${env.PATH}"
"jdk1.8.0_111" beeing the name of the java configuration initially registered into Jenkins
On CentOS 6.x and Redhat 6.x systems, the openjdk-devel package contains the jdk. It's sensible enough if you are familiar with the -devel pattern used in RedHat, but confusing if you're looking for a jdk package that conforms to java naming standards.
I was facing the same issue and for me downgrading the JAVA_HOME from jdk12 was not the plausible option like said in the answer. So I did a trial and error experiment and I got the Jenkins running without even downgrading the version of JAVA_HOME.
Steps:
open configuration $ sudo vi /etc/init.d/jenkins
Comment following line:
#JAVA=`type -p java`
Introduced the line mentioned below. (Note: Insert the specific path of JDK in your machine.)
JAVA=`type -p /usr/lib/jdk8/bin/java`
Reload systemd manager configuration: $ sudo systemctl daemon-reload
Start Jenkins service: $ sudo systemctl start jenkins

I just wanted to add a solution for Windows machines.
Windows Server 2008 R2 Standard, SP1
Jenkins 2.89.4
Java version 8.171
Symptom: Jenkins service starts and immediately stops.
Jenkins.wrapper.log has a line indicating the incorrect path to Java:
- Starting C:\Program Files\Java\jre1.8.0_141\bin\java -Xrs -Xmx6g -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "C:\Program Files (x86)\Jenkins\jenkins.war" --httpPort=8080 --webroot="C:\Program Files (x86)\Jenkins\war"
The fix: Jenkins has the path hard-coded in jenkins.xml. Change the path to the new Java location.
<env name="JENKINS_HOME" value="%BASE%"/>
<!--
if you'd like to run Jenkins with a specific version of Java, specify a full path to java.exe.
The following value assumes that you have java in your PATH.
-->
<executable>C:\Program Files\Java\jre1.8.0_171\bin\java</executable>
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"</arguments>
You can also use Windows Environment Variables, but I wasn't successful with that and I don't think the Java installer updates those, so you'd need to update that by hand every time anyway.
<env name="JENKINS_HOME" value="%BASE%"/>
<!--

openjdk-6 is a Java runtime, not a JDK (development kit which contains javac, for example). Install openjdk-6-jdk.
Maven also needs the JDK.
[EDIT] When the JDK is installed, use /usr/lib/jvm/java-6-openjdk for JAVA_HOME (i.e. without the jre part).
This is an old thread but for more recent Jenkins versions (in my case Jenkins 2.135) that require a particular java JDK the following should help:
Note: This is for Centos 7 , other distros may have differing directory locations although I believe they are correct for ubuntu also.
Modify /etc/sysconfig/jenkins and set variable JENKINS_JAVA_CMD="/<your desired jvm>/bin/java" (root access require)
Example:
JENKINS_JAVA_CMD="/usr/lib/jvm/java-1.8.0-openjdk/bin/java"
Restart Jenkins (if jenkins is run as a service sudo service jenkins stop then sudo service jenkins start)
The above fixed my Jenkins install not starting after I upgraded to Java 10 and Jenkins to 2.135
java jenkins java-home ubuntu centos
For those of you coming to this issue and have access to configure your Jenkins Agents, you can set the JAVA_HOME from the Jenkins > Nodes > "the agent name" > Configure page:
Setting "per agent" environment variables
In case anyone has similar problems, I used the default sudo apt-get installs for the relevant packages and here are the correct settings:
JAVA_HOME=/usr/lib/jvm/java-7-openjdk-i386
and
MAVEN_HOME=/usr/share/maven2
In Jenkins try setting JAVA_HOME to /usr/lib/jvm/java-6-openjdk
Upgrading from Ubuntu 10.0.4 to 12.0.4 we got wrong footed.
We had a JDK installation configured (auto-configured?) pointing to /usr/lib/jvm/java-6-openjdk
this no longer contained a JDK,
Changing to /usr/lib/jvm/default-java fixed, and should make for a seamless java-7 upgrade.
So in answer to the question: do not specify JAVA_HOME on Ubuntu.
In Ubuntu 12.04 I had to install
openjdk-7-jdk
then javac was working !
then I could use /usr/lib/jvm/java-7-openjdk-amd64 as path and jenkins didn't complain anymore.
Download package rpm package from http://pkg.jenkins-ci.org/redhat/ you can give additional java location like I have default 1.7 java in my system but I am using /opt/jdk1.8.0_60/bin/java for jenkins. Open jenkins startup script /etc/init.d/jenkins and add additional java here, I m case I have added /opt/jdk1.8.0_60/bin/java,
Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.

i found the directory of java_home
so it's
