Hmm. Looks ok (but I don't use annotations, either). Are you sure
that the hivemodule.xml file is being copied over to the classes
directory? Check that.
I find it easier (for webapps) to just drop it directly in the WEB-INF
directory. Since you're typically running tomcat with the docBase
pointing back to your project (for development, anyway -- and likely
so if you are using Kent's book) this should work fine.
