I have a Tomcat7 install on a CentOS (6.7) system. Tomcat will not run, throwing exception in catalina.out
```
/usr/sbin/tomcat: line 29: -classpath: command not found
```
and related tomcat-initd.log
```
/usr/sbin/tomcat: error: Failed to set JAVACMD
```
According to this SF post, I should be able to set it in /usr/share/java-utils/java-functions like this:
```
# Add all sorts of jvm layouts here
  if [ -x "$JAVA_HOME/jre/sh/java" ]; then
    JAVACMD="$JAVA_HOME/jre/sh/java"
  elif [ -x "$JAVA_HOME/bin/java" ]; then
    JAVACMD="$JAVA_HOME/bin/java"
  else
    JAVACMD=`which java 2>/dev/null`
  fi

  if [ ! -x "$JAVACMD" ]; then
    echo "$0: error: Failed to set JAVACMD"
    return 1
  fi
```
But I still get the exception. What's missing? What am I not understanding, and how do I resolve the exception?

JAVA_HOME is set:
```
echo $JAVA_HOME
/usr/java/jdk1.7.0_79
```
Checking tomcat status:
```
sudo service tomcat status
PID file exists, but process is not running                [WARNING]
tomcat lockfile exists but process is not running          [FAILED]
```
This is true even after deleting the Tomcat pid file, rinsing and repeating.

Request responses:
```
whereis java
java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java

ls -lad /usr/bin/java
lrwxrwxrwx. 1 root root 21 Jul 21  2015 /usr/bin/java -> /usr/java/jre1.8.0_51

ls -lad /etc/alternatives/java
lrwxrwxrwx. 1 root root 20 Jul 21  2015 /etc/alternatives/java -> /usr/java/glassfish4
```
after commenting out JAVA_HOME in tomcat.conf
```
/etc/rc.d/init.d/tomcat start
Starting tomcat:                                           [  OK  ]
sudo service tomcat status
tomcat (pid 13517) is running...                           [  OK  ]

  Could you run 'whereis java' and show the output?

  Your JAVA_HOME does not seem to match your installed JAVA.

  comment JAVA_HOME in the /etc/tomcat/tomcat.conf and then run 'JAVA_HOME=/usr/java/jre1.8.0_51 bash -x /usr/sbin/tomcat version'

  Possible duplicate of CentOS, Tomcat 6 failed and won't start - java issue?
