Cannot load Woody component

[Upayavira]

(ignore previous message - premature send :-(

I've started working with Woody (which seems impressive). I have just 
started getting the following:

ConfigurationException: Could not load class 
org.apache.cocoon.woody.acting.MakeFormAction for component named 
'woody-make-form' at 
file:/D:/documents/cocoon/cocoon%20dev/build/webapp/woody/sitemap.xmap:28:108

I had this problem originally, then it resolved itself and I was able to 
get on. It has now restarted.The block is included, and the jar file is 
in the lib directory.

Any ideas where to look?
