Hard to tell without the code, but a lot of times the error is the component metadata is not present or it's wrong. If you hand wrote it you might have a typo, or you might not have the metadata generators configured.

The Last Hero Thanks, Jason ---------------------------------------------------------- Jason van Zyl Founder, Apache Maven http://twitter.com/jvanzyl http://twitter.com/takari_io --------------------------------------------------------- Our achievements speak for themselves. What we have to keep track of are our failures, discouragements and doubts. We tend to forget the past difficulties, the many false starts, and the painful groping. We see our past achievements as the end result of a clean forward thrust, and our present difficulties as signs of decline and decay. -- Eric Hoffer, Reflections on the Human Condition
