Spring Cloud Micro Services

Hi, I am trying to get the Zuul proxy to work in Spring for the Micro Services architecture and I am following Josh's video ([login to view URL]). In that he is not creating a RestTemplate object, but merely declaring it and getting it Autowired. But when I do that, Spring can't intialiase the bean and it complaints which pushes me to create the rest template. Then with that, when I call the exchange method on the rest template, I get service not found exception, even though eurka service shows the service I am accessing registered. I feel it's because of a configuration issue thus would like to get some help from an expert to get things going. Thanks
