We followed the steps to install neo4j and create service from installation link

We were able to create the service on our linux machine but its giving the following Error of Java path.

[root@localhost Desktop]# service neo4j-service status
which: no java in (/sbin:/usr/sbin:/bin:/usr/bin)
ERROR: Unable to find java. (Cannot execute )
* Please use Oracle(R) Java(TM) 7 or OpenJDK(TM) to run Neo4j Server.
* Please see http://docs.neo4j.org/ for Neo4j Server installation instructions.[root@localhost Desktop]# 

On echo $JAVA_HOME = /usr/java/jdk1.7.0_71/bin/java

On echo $PATH= /usr/local/apache2/bin:/usr/java/jdk1.7.0_71/bin:/usr/local/apache2/bin:/usr/java/jdk1.7.0_71/bin:/usr/lib/qt-3.3/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/root/bin:/root/bin

Where is the problem in starting the service?
