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

Solution 1

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.

Solution 2

1. Add JAVA_HOME variable to .bash_profile

2. Add path/classpath entries

3. Export them

e.g.

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

export JAVA_HOME PATH CLASSPATH
