Jersey + Spring 3 + Maven 3 + Tomcat 7 @Resource in @Component Class are always null

I have searched and tried about everything I can think of to fix this but the Dao in the TestService class is always null. I see the Spring logs showing that the Dao is injected as well as the TestService class. I have tried running under WTP for eclipse as well as straight up in Tomcat. Both result in the same error. Can anybody please help decipher where the error is that causes the Dao to be null in the TestService Class.
