Browsers and Java 1.6 on MacOS 10.5.8

I am trying to load an applet that requires Java 1.6. I am running MacOS 10.5.8 on an Intel machine with all updates installed. Java Preferences shows the following boxes checked:

Java SE 6 64-bit 1.6.0_24-b07-334

J2SE 5.0 32-bit 1.5.0_28-b04

J2SE 5.0 64-bit 1.5.0_28-b04

I went to the Sun Java test site here, and it told me my Java version was J2SE Runtime 5 Update 28.

This page gave instructions for changing Java versions.

java version "1.6.0_24"

Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-9M3326)

Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)

So the OS is now telling me that the default version of Java is version 1.6.

However, even after restarting my computer, I still can't load the applet, and Sun is still telling me that I am running J2SE Runtime 5.

I see the same symptoms in both Safari 5.0.5 and Firefox 3.6.17.

Is there a way to tell Safari or Firefox to use Java 1.6 on MacOS 10.5.8?
