406 Not Acceptable Spring Rest WS - spring

Question

I am writing a spring rest WS to return response as XML. Below are my classes and pom file.
I am getting Http 406 Error on executing the service as below:
http://localhost:8080/SpringRestExample/rest/emp/dummy.xml
However, I am getting the JSON response back when executing
http://localhost:8080/SpringRestExample/rest/emp/dummy.json
Please advise
pom.xml
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>${jackson.version}</version>
</dependency>
EmployeeController:
#RequestMapping(value = "/rest/emp/dummy", method = RequestMethod.GET,produces={"application/xml"})
public #ResponseBody Employee getDummyEmployeeXML() {
logger.info("Start getDummyEmployee");
Employee emp = new Employee();
emp.setId(9999);
emp.setName("Dummy");
emp.setCreatedDate(new Date());
empData.put(9999, emp);
return emp;
}

Answer 1

406 means that the server is not able to produce a response in the content type asked by the client. Check the Accept header of your HTTP request, and make sure it contains application/xml.
Maybe it contains text/xml, and that's what you should use in the producesattribute of your #RequestMappingannotation. BTW, you should use the constants in org.springframework.http.MediaType instead of hard-coding the string as you're doing.

Answer 2

for any type of xml conversion you need to add #XmlRootElement annotation on top of Model class. i have done the changes and run the above program and got the result.Just add #XmlRootElement above Employee class and you are done.
