OK, I'm reading this and it seems to be saying to copy JARs over the $JAVA_HOME/lib/security.

Instead, can I put that path in the CLASSPATH in front and override it that way?

Then when maintenance gets applied, I won't get stomped on...

Has anybody tried this?

Do you use JKS on USS or AT-TLS from RACF?

Well, I got this to work.

We did copy the JAR files from the $JAVAHOME/demo/jce/policy-files/unrestricted to $JAVAHOME/lib/security and updating the CLASSPATH did not work. I guess it all gets loaded before the CLASSPATH gets a chance to override stuff.

Note that $JAVAHOME is what z/OS WMB uses and not $JAVA_HOME.

I see references to both in my ENVFILE and they do not point to the same version of Java...

To build the JKS key store (and I didn't build a separate trust store), I used the keytool program that gets delivered with Java. Oddly enough, I had to build a self signed key to build the key store. Then I build a certificate request based on that key by the label name. Signed it with my CA and received it. You may need to tinker with the keytool options as I don't think the doc is 100% correct. Imported a CA with a 4K key and all worked.

Since mine was outbound, I don't know if I needed a key for the broker but I built one anyway just because I didn't want to take another iteration.
