Is it possible to use environment variables like %JAVA_HOME% within eclipse.ini?
I'd like to include the following without having to hardcode the absolute path to jdk:
-vm
%JAVA_HOME%\bin\javaw.exe
But that's not working and eclipse complains about missing jdk.
By the way: cmd echo %JAVA_HOME% shows the correct path.

It is not possible. There is already a bug opened for this.

I have developed a JAVA application for signature verification and I want to develop an Apache Nifi Processor for this JAVA application.
When I want to run .bat file in cmd i.e. run-nifi.bat I get this error :
"The JAVA_HOME environment variable is not defined correctly. Instead
the PATH will be used to find the java executable."
Also I can not find my processor at http://localhost:8080/nifi
Just define JAVA_HOME system environment variable and point it to your JDK dir. More detailed answer: How to set java_home on Windows 7?

Find the java.exe location from java [duplicate]

Get path to java JRE

I am wondering if there is a way, from java, to find the location of the java.exe running the program?
My use case is that I am trying to have Java execute a batch script that needs JAVA_HOME to be set in the local environment. The environment that I am executing this on may not have JAVA_HOME set or even the java executable on the path, but I would assume that the JVM knows where its executable is located.
System.getProperty("java.home");
is one option. Which shows the following directory in my machine:
C:\Program Files\Java\jdk1.7.0_02\jre
Most important system properties are listed here.
The java.home property will supply the path to the currently running JRE, regardless of what is installed, or what JAVA_HOME is. See the Oracle documentation here.
System.getProperty("java.home");

I need help with getting path to java.exe. But I need it to do with java code. And I want it to work on Linux and Mac and on other systems too, so there won't be java.exe, I don't know what's there.
Does anyone know how to do it? Thanks.
Take a look at this post. Get path to the JRE
It explains how to get the path of where your java.exe bin/java file lies on your OS.

Add these lines at the end of the user profiles in the ~/.profile file or, as a superuser, at the end of the global profiles in the /etc/profile file.
export JAVA_HOME=<jre installation home directory like /usr/lib/jvm/jrel.8.0>
export PATH=$JAVA_HOME/bin:$PATH
Logout and login again.
