How to call an embedded jre from command line in order to run java applications

Is it possible to bundle a JRE within an exported stand alone Java app? We have a very specific requirement to run a standalone AnyLogic Java app on a machine that does not have the latest Java version installed and due to company IT policies we will not be able to do so

Through some research I have found some sites to claim that they have already been doing it for Windows and Mac.

Using a bundled JRE on OSX

My issue is that most of these posts refer to bundling an app for Mac OS x and requires that the jar files be created in an IDE like Eclipse. But since I use AnyLogic the jar files gets exported without myself being able to intervene. What I need is to change the command line code that runs the jar files and currently looks like this:

java -Xdock:name="AnyLogic Model" -Dnativewindow.awt.nohidpi=true -cp com.anylogic.engine.jar:com.anylogic.engine.nl.jar:lib/database/querydsl/querydsl-sql-codegen-3.6.3.jar -Xmx256m model6.Simulation $*

(Note: Code reduced for readability)

into something that I assume will pass the jre or JVM to be used as an argument to the java call. Or maybe set the directory to be used for java or something... as calling the java command on a machine without java installed renders nothing.

I have a very simple app, as well as a jdk plugin that I got from the moneydance app, which is a java app that runs on OSx with its own embedded jre, available here




A colleague of mine who is not on Stack Exchange gave me the answer so here goes, actually quite easy:

In order to meet my specific circumstances one just needs to include a jre and then reference the the java executable in the execution file. The solution for Windows and Mac are slightly different so here goes:

On Mac

You can find the jre in the following folder. It is a hidden folder so if you Mac is not set to show hidded folders go to finder use command-shift-g and go to


there should be a jdk folder and then navigate to


On Windows

The location of the jre is in

c:\Program Files\Java\

you can see the location in the .bat file that AnyLogic creates automatically in line of code that looks like this:

@SET PATH_XJAL="%DISK_XJAL%\Program Files\Java\jre6\bin\java.exe"

Once you have the jre copy this folder to the same location as the stand alone java app. Then the only thing that remains is to change the referenced location in both mac command line executable and the windows.bat file

On Mac

Change from

java -Xdock:name="AnyLogic Model"


./jre/bin/java -Xdock:name="AnyLogic Model"

On Windows

Change from

    @SET PATH_XJAL="%DISK_XJAL%\Program Files\Java\jre6\bin\java.exe"


   @SET PATH_XJAL= \jre6\bin\java.exe"

Running the java app on both Mac and Windows will now be independent from the Java version on the machine or whether it is installed or not
