WLST script without a plain text password

One of the things that has annoyed me about WLST is the seemingly missing method of being able to invoke a WLST script without having a plain text userid and password either in the script or in a properties file. I came across a great post on the Oracle Blogs today by Bola Kothandaraman that describes how you can have a WLST script without having a plan text username and password to your admin Server. It's similar to the boot.properties file, but there are some nuances of this method that are described pretty well in this post (at least I think they are... see my current script issue below): http://blogs.oracle.com/bala/2008/09/encrypt_the_credentials_when_r.html UPDATE: I originally had posted that I was having issues with this method, but I found my problem, and it was a super dumb mistake on my part which I fixed and tested this morning. The method described above is working like a charm and I'm happy to understand how to use WLST without a plain text username and password now.
