Unable to load Java Runtime Environment with embedded jre

I am trying to bundle a java application on windows for mac using appbundler-1.0.jar and Ant with an embedded jre 7.

This is the build.xml:

    <?xml version="1.0" encoding="UTF-8"?>
    <project name="AppName" default="default" basedir=".">
        <property environment="env" />
        <taskdef 
            name="bundleapp" 
            classname="com.oracle.appbundler.AppBundlerTask" 
            classpath="lib/appbundler-1.0.jar" />
        <target name="bundle-AppName">
            <bundleapp 
                outputdirectory="dist" 
                name="AppName" 
                displayname="AppName" 
                identifier="com.hmf.AppName" 
                icon="files\logo48.icns"
                shortversion="1.0"
                mainclassname="hmf.AppName.app">
                <classpath file="files/AppName.jar" />
                <librarypath dir="pathToLibraries" />
                <option value="-Dapple.laf.useScreenMenuBar=false"/>
                <option value="-XstartOnFirstThread=true"/>
                <option value="-Dcom.apple.macos.useScreenMenuBar=false"/>
                <option value="-Dcom.apple.smallTabs=true"/>
                <option value="-Dsun.java2d.d3d=false"/>
                <option value="-Derby.storage.pageSize=8192"/>
                <option value="-Djava.library.path=lib/swt.jar:lib"/>
                <option value="-Xmx1400M"/>
            </bundleapp>
        </target>
    </project>

I then copy jre 7 for mac to PlugIns directory under AppName.app. (I cant make it work with the runtiime tag)

But when I try to run the application I get: "Unable to load Java Runtime Environment".

When OS use system jre it works but I want to be able to use the embedded jre.

Also see:
http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html
Application is using Java 6 from Apple instead of Java 7 from Oracle on Mac OS X?

I've solved the issue with my "Unable to load Java Runtime Environment" by using an installed JDK as the jre to be embedded within my app. I was until now using a jre unzipped within a user folder. with the JDK I set the environment variable at the command line

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home

I then used the 

<runtime dir="${env.JAVA_HOME}" />

and it worked as the jre gets installed under the Plugins directory as it should i.e no need to manually copy jre
