Tomcat 7: "Cannot locate Java Home"

Question

Arch Linux. Servlet apparently had compatibility problems with openjdk so I uninstalled it and installed the plain jdk/jre from AUR.

# /etc/rc.d/tomcat7 restart
:: Stopping tomcat7 daemon [FAIL] 
:: Starting tomcat7 daemon [BUSY]
Cannot locate Java Home

Added export TOMCAT_JAVA_HOME=/opt/java to /etc/profile.d/jdk.sh (and equivalent under jdk.csh), rebooted. echo $JAVA_HOME and echo $TOMCAT_JAVA_HOME both return /opt/java, but still no dice. Why?

Solution

I solved this issue following this page: https://bugs.archlinux.org/task/24126

Basically you have to add these lines in your /etc/rc.d/tomcat7 file, below the line ". /etc/conf.d/${daemon_name}"

# The JAVA_HOME of the JVM for Tomcat to use

if [ -x /usr/lib/jvm/java-6-openjdk ]; then
TOMCAT_JAVA_HOME=/usr/lib/jvm/java-6-openjdk
elif [ -x /opt/java/ ]; then
TOMCAT_JAVA_HOME=/opt/java/
fi

# Tomcat additional commandline options
CATALINA_OPTS=

Hope this helps.

I was already root; no sudoing involved. Tried your solution anyway though; didn't work.

javac exists, yeah. As I said I installed the JDK from AUR (community repo). which java is /opt/java/bin/java. No alternatives system on Arch. Anyway, Java is already in my PATH. Haven't edited any existing variables; only added a new one (TOMCAT_JAVA_HOME).

Tried this. Didn't work.

@Hugh Guiney - what happens when you try robregonm's answer? Also, when you set your var do you also export it? This shouldn't be this hard of an issue and you have given us limited information. Can you possibly post your start script or is it too long?
