How can I specify the default MimeType returned by a REST resource with Jersey - rest

Question

I am creating a REST interface and have a resource 'data'. Now I want that an user can specify whether he wants the data as XML or as JSON. Therefore I have created two methods for the same path, one produces application/xml, the other produces application/json. Everything works fine, but how can I specify what should be returned, if an user doesn't set the 'Accept' header field?
My tests have shown that it is not always the same. Yesterday the default was application/xml, today my tests have failed, because as default application/json was returned.
How can I specify a default?
Code Snippet:
#GET
#Path("/rest/data")
#Produces(MediaType.APPLICATION.XML)
public Object getDataAsXML() {
// return data in XML format
}
#GET
#Path("/rest/data")
#Produces(MediaType.APPLICATION_JSON)
public Object getDataAsJSON() {
// return data in JSON format
}

Answer 1

#Path("/myResource")
#Produces("text/plain")// doGetAsPlainText method defaults to the MIME type of the #Produces annotation at the class level.
public class SomeResource {
#GET
public String doGetAsPlainText() {
...
}
#GET
#Produces("text/html")
public String doGetAsHtml() {
...
}
}
The doGetAsPlainText method defaults to the MIME type of the #Produces annotation at the class level. The doGetAsHtml method's #Produces annotation overrides the class-level #Produces setting, and specifies that the method can produce HTML rather than plain text.
#GET
#Produces({"application/xml", "application/json"})
public String doGetAsXmlOrJson() {
...
}
The doGetAsXmlOrJson method will get invoked if either of the media types "application/xml" and "application/json" are acceptable. If both are equally acceptable then the former will be chosen because it occurs first.
