Specify JRE/JDK when starting Apache Tomcat 7

Question

Is there a way to tell Tomcat 7 the path to the JVM that must be used? For example:

startup --jvm /path/to/my/jvm

Is there a way to do this in Ubuntu that is system-specific? I shall scour AskUbuntu as well.... — icedwater, Jul 23 '13 at 03:52

A more flexible approach is to create a file named setenv.bat / setenv.sh (pick the right one for your platform) in $CATALINA_BASE/bin and set JAVA_HOME there. That way it only affects Tomcat, not anything else you are running. It also makes it easy to run multiple different Tomcat installations on different JVMs.

This is helpful. Is this documented on Tomcat's site? (As opposed to only knowing this by viewing the source files.) – Michael Plautz Mar 05 '15 at 10:31
See RUNNING.txt in the root of every Tomcat installation. – Mark Thomas Jun 23 '15 at 20:28

Add JAVA_HOME variable to .bash_profile
Add path/classpath entries
Export them

e.g.

JAVA_HOME=/usr/local/java
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib

export JAVA_HOME PATH CLASSPATH
