Well in fact the traffic uses ajp13, a protocol which is not really
"clear text". It's a binary format for optimization reasons.
Nevertheless it's of course not crypted (if you know the protocol), but
it might suffice for "minor" security demands as you cannot simply read
it using sniffer tools.

For mod_jk and Tomcat I doubt you can encrypt it. I never
heard/read/seen anything in the docu, too.
You could maybe try things with an ssl tunnel like, but
that's just a guess...

BTW: Why is the communication between Apache and Tomcat an issue at all?
Usually/Hopefully you're already in a "secure" environment with your
Apache behind a firewall etc.
