Hey David,

I was mistaken, jetty-6.1.25 was in the lib, but here's the error:

INFO   | jvm 1    | 2010/08/12 05:19:38 | WrapperSimpleApp: Encountered an
error running main: java.lang.NoClassDefFoundError:
org/mortbay/jetty/HandlerContainer
INFO   | jvm 1    | 2010/08/12 05:19:38 | java.lang.NoClassDefFoundError:
