Subject Re: ClassCastException with betwixt 0.6

Thanks a bunch for helping me out. I was able to get the example
working. It seems my problem was related to classpath and not using
the correct dependencies. I ran "ant get-deps" to create target/lib
and copied those jars to my sandbox lib directory. After doing that
the example code ran as expected.

Maven looks very interesting. Up until this point I had only used ant
as a build tool.

Again thanks for the tips and patience.
