Default JAva version in this machcne is java6,  while start MS, we need to pick java7 from /usr/lib/jvm/jre-1.7.0 or $JAVA_HOME

We need to fix this in classpath.conf


export CLASSPATH
if   [[ ! -d "$JAVA_HOME" && -d /usr/lib/jvm/jre-1.7.0 ]]; then
     export JAVA_HOME=/usr/lib/jvm/jre-1.7.0
fi
PATH=$JAVA_HOME/bin:/sbin:/usr/sbin:$PATH
export PATH
