This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I believe you'll find these classes in the JCE API (http://java.sun.com/products/jce/index.html). You can double check by either scanning the java docs or examining the contents of the jar file using the command jar -tf xxx.jar or, if you want to examine a specific package (i.e. is this package in there?), do this. jar -tf xxx.jar com.sun This will only list classes below that package. Hope this helps. Sean
