Is there a way to load a different cacerts than the one specified in the java_home/jre/lib/security folder?

I have a single installation of java in a system that runs 2 or 3 applications.

All the applications use the same runtime.

Is there a way to specify a different keystores for the ca certs than the one in java_home/jre/lib/security. That is, is there an option to specify an "extra" keystore that is loaded and added to the certs loaded from java_home/jre/lib/security/cacerts?

What I want to avoid is having to re-import our local ca every time I upgrade the jdk in the box.

I think you want to specify the truststore:

java -Djavax.net.ssl.trustStore=/home/gene/mycacerts ...

Or if you are using certs through JSSE (you probably are), you can copy your truststore to jssecacerts in the $JAVA_HOME/jre/lib/security/ directory (although you'd still have to do that each time a JDK got installed/reinstalled). Sun's JSSE looks for $JAVA_HOME/jre/lib/security/jssecacerts before $JAVA_HOME/jre/lib/security/cacerts.

See http://java.sun.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#X509TrustManager

According to this:

Java SSE Referece Guide - Customization

You could use the system property:

javax.net.ssl.keyStore

Like: 

java -Djavax.net.ssl.keyStore=youkeystore YourProgram

But!! I have never tried. Let me know if it works would you?
