Looking for help

Hi I am desperatly trying to install BubbleUPnPServer on my Unraid but am having difficulty.  I would like to have this installed as it creates OpenHome Media Renderers from any UPnP AV renderer (provides on-device playlist, multiple Control Point access to the same renderer) this would allow me to control my music in any room via various IOS apps allowing me to create playlists on the app etc (my preferred app is the Lumin App)  There was an Unraid user who did have this working on his unraid but has since abandoned Unraid.  sam9s http://www.hifivision.com/home-theater-pc-htpc-media-pc/28439-part-ii-sam9s-nas-project-powered-unraid-2.html his instructions on installation was to install Java from unmenu but Buuble now requires Java7 or above.

I have installed http://www.slackware.com/~alien/slackbuilds/openjdk/pkg/13.37/openjre-7u71_b14-i486-1alien.txz via the extra folder on my flash drive.  when I run find /usr -name java and have the following output

/usr/lib/java

/usr/lib/java/jre/bin/java

To get Bubble to start you need to edit the launch.sh file add on the last line the java path which I have done

#!/bin/sh

HOMEDIR="$(dirname ${0})"

cd ${HOMEDIR}

if [ "x$JAVA_HOME" != "x" ]; then

    JAVA="$JAVA_HOME/bin/java"

else

    JAVA="java"

fi

# to make sure ffmpeg is found and used if present in start directory

export PATH=.{PATH}

# -Xss256k: thread stack size. 256K reduces per-thread memory usage and may prevent "java.lang.OutOfMemoryError: unable to create new native thread" on some systems

# -Djava.awt.headless=true: required for image transcoding to work on headless systems (eg no X-Window libraries)

exec "${JAVA}" -Xss256k -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dfile.encoding="UTF-8" -jar BubbleUPnPServerLauncher.jar exec java -Xss256k /usr/lib/java/jre/bin/java -jar BubbleUPnPServer.jar

but when I run the launch.sh file I get this

root@Tower:/boot/BubbleUPnPServer# ./launch.sh

./launch.sh: line 20: /usr/lib/java/bin/java: No such file or directory

./launch.sh: line 20: exec: /usr/lib/java/bin/java: cannot execute: No such file or directory

what am I missing here many thanks any help would be appreciated
