Question

Does anyone know how to downgrade the version for JRE/JDK from 1.6.0_24 to 1.6.0_18 on a Mac OSX thru Terminal? I need to downgrade in order to get a Java applet working in

I've had the very same problem. You can open the JRE 1.6.0_20 image file with Pacifist software and extract all the folders with the framework into the \System\Library\Frameworks\JavaVM.framework\Versions folders. After that the JRE should appear in your Applications/Utilities/Java Preferences JRE selection menu, where you can switch between the running JRE's.
