Spring RESTful Client/Server tutorial

[Toxic]

I used this example and I have a problem. here is the error stack :

javax.servlet.ServletException: Could not resolve view with name 'jaxbView' in servlet with name 'LabResult'
org.springframework.web.servlet.DispatcherServlet. render(DispatcherServlet.java:1029)
org.springframework.web.servlet.DispatcherServlet. doDispatch(DispatcherServlet.java:817)
org.springframework.web.servlet.DispatcherServlet. doService(DispatcherServlet.java:719)
org.springframework.web.servlet.FrameworkServlet.p rocessRequest(FrameworkServlet.java:644)
org.springframework.web.servlet.FrameworkServlet.d oGet(FrameworkServlet.java:549)
javax.servlet.http.HttpServlet.service(HttpServlet .java:690)
javax.servlet.http.HttpServlet.service(HttpServlet .java:803)

You need two things:

1.

<!-- Resolve views based on string names -->
<bean class="org.springframework.web.servlet.view.BeanNa meViewResolver" />


2.

<!-- XML view using a JAXB2 marshaller -->
<bean id="jaxbView" class="org.springframework.web.servlet.view.xml.Ma rshallingView">
<constructor-arg ref="jaxbMarshaller" />
</bean>


And

I did all of that, here is my labresult-servlet.xml

the index page get displayed as it doesn't pass through the servlet but all other pages gives the same error

Please use code tags when displaying code. Also, could it be that you only map ".list" operations in your web.xml?

[Itf]

Thanks Toxic,
I wanted to only map ".list". Should I map any thing else? in my controller, I only need ".list"
here is my controller:

@Controller
public class LabResultController {

	private ResultServiceDAO resultServiceDAO;
      @Autowired
	public void setResultServiceDAO(ResultServiceDAO resultServiceDAO) {
		this.resultServiceDAO = resultServiceDAO;
	}
      @RequestMapping(method = RequestMethod.GET, value = "/labresult.list")
	public ModelAndView myRestMethod() {

		result = resultServiceDAO.getResultProfileByResultId(0);
		if (!result.isEmpty()) {

			return new ModelAndView("labresult", "response", result);
		} else
			return null;
	}
}

[Toxic]

It seems that either your spring-config is not picked up properly or that your controller mappings are not. I'm not sure whether there's case-sensitivity involved in your servlet (e.g., try naming it lowercase "labresult"). In the latter case, you should also supply the beans

<context:component-scan base-package="my.controller.package"
<annotation-driven/>

That was a great post. Nice work. Even two years later, it is one of the more concise write-ups I have seen.
