How do you get Safari 7 on Mavericks 9.1 to use Java 6?

I have one old website that use the Java plug-in. It does not work with Java 7. On the new iMac, Java 6 is installed.

I have a few apps that use Java and they all have no problem finding Java 6. But Safari 7 does not even see the installed Java 6, although when the site was first accessed and you clicked on the missing plug-in button, Java 6 was installed.

All help sites refer to Safari preferences to enable Java, but this preference doesn't exist in Safari 7. There is a manage plug-in option, but Java is not listed. I'm thinking maybe Safari 7 is looking at a new location for Java and I may be able to add an alias to point to Java 6.
