Planet M.U.L.E.

I downloaded the game today and got the ELFCLASS32 error as described in http://vsingleton.blogspot.com/2012/03/wrong-elf-class-elfclass32-possible.html (http://vsingleton.blogspot.com/2012/03/wrong-elf-class-elfclass32-possible.html). I followed the instruction and got the error

./mule.sh: 11: ./mule.sh: /bin/java: not found

I ran "whereis java" and got

java: /usr/bin/java /usr/share/java /usr/share/man/man1/java.1.gz

So I simply added the line "JP=/usr/bin/java" to mule.sh. Now running ./mule.sh works up to when I see the message "INFO: Launching game" after which of course the game doesn't launch. What should I do next?

Output of "./mule.sh" below:

My modified mule.sh file below:

#!/bin/sh
cd data
export LD_LIBRARY_PATH=.:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64
if [ -f /usr/lib/jvm/java-6-sun/bin/java ]; then
   JP=/usr/lib/jvm/java-6-sun/bin/java
elif [ -n $JAVA_HOME ]; then
   JP=$JAVA_HOME/bin/java
else
   JP=java
fi
JP=/usr/bin/java
$JP -jar ./launcher.jar nohup $JP -Xms64m -Xmx256m -Djava.library.path=lib -jar ./data.jar

For now I worked around this by running the Vista version with Wine. Seems to be working fine for now.
