How to change JAVA_HOME and JAVA_OPTS on Tomcat installed on Linux?

I have a version of Tomcat 5.5 installed on Linux with a package, and while I am used to deal with sh scripts stored in the Tomcat bin directory, here /usr/share/tomcat5/bin doesn't contain the usual scripts and Tomcat is started instead with /usr/java/latest/bin/java. Do you have any advice on how to change the JAVA_HOME and JAVA_OPTS (to set VM parameters such as heap size) in this environment?

In the file /etc/profile add the following after "export path":

JAVA_HOME= your jdk directory e.g. /usr/lib/jdk
export JAVA_HOME

export PATH=$JAVA_HOME/bin:$PATH

Thank you for the tip. But I have been already trying to set JAVA_OPTS and JAVA_HOME in /etc/profile, but that didn't have any effect.

Probably, you should set these parameters to the shell environment of the
user with which you are executing the tomcat startup script - probably on
his/her profile.

Uninstalling and reinstalling the JDK and Tomcat packages solved the problem. And after this, setting the variables in /etc/profile works. Thanks guys.
