security - How to obtain the location of cacerts of the default java installation?

Question

I am looking on how how to obtain the location of cacerts of the default java installation, when you do not have JAVA_HOME or JRE_HOME defined.

I need a solution that works at least for OS X and Linux.

Yes. java -v is assumed to work :)

Answer 1

Under Linux, to find the location of $JAVA_HOME:

readlink -f /usr/bin/java | sed "s:bin/java::"

the cacerts are under lib/security/cacerts:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

Under mac OS X , to find $JAVA_HOME run:

/usr/libexec/java_home

the cacerts are under Home/lib/security/cacerts:

$(/usr/libexec/java_home)/lib/security/cacerts

UPDATE (OS X with JDK)

above code was tested on computer without JDK installed. With JDK installed, as pR0Ps said, it's at

$(/usr/libexec/java_home)/jre/lib/security/cacerts
