I'm getting an exception trying to configure a custom media type:
SEVERE: A message body writer for Java type, class
mil.cnodb.rs.model.v1.NodeV1, and MIME media type,
application/v1-xml, was not found

How can I map application/v1-xml to application/xml? Similarly with
application/v1-json. Is there a way to avoid writing a custom
messageWriter for the media type?
I've configured a context resolver:
/**
*
*/
@Provider
@Produces({"application/v1-xml","application/v1-json"})
public final class Version1ContextResolver implements
ContextResolver<JAXBContext> {
private final JAXBContext context;
private final Set<Class> types;
/*
* The list of JAXB class types (top-level) need to be listed here.
*/
private final Class[] cTypes = {NodeV1.class};
public Version1ContextResolver() throws Exception {
this.types = new HashSet(Arrays.asList(cTypes));
this.context = new JSONJAXBContext(
JSONConfiguration.natural().build(), cTypes);
}
public JAXBContext getContext(Class<?> objectType) {
return (types.contains(objectType)) ? context : null;
}
}
Created a Resource that
Produces("application/v1-xml","application/v1-json")
@GET
@Produces({"application/v1-xml","application/v1-json"})
public NodeV1 getNode(
@QueryParam("id") String nodeId,
@QueryParam("name") String nodeName,
@QueryParam("level") String nodeLevel,
@QueryParam("allegiance") String allegiance,
@QueryParam("cc") String cc,
@QueryParam("typeGeneral") String
nodeTypeGeneral,
@QueryParam("typeSpecific") String
nodeTypeSpecific) {
NodeV1 nodeV1 = new NodeV1();
nodeV1.setNodeName("Nodes Name is");
return nodeV1;
}
Extended PackagesResourceConfig:
public class CnodbRestResourceConfig extends PackagesResourceConfig {
public CnodbRestResourceConfig() {
super(createProperties());
}
public Map<String, MediaType> getMediaTypeMappings() {
Map<String, MediaType> m = new HashMap<String, MediaType>();
m.put("v1-xml", CnodbMediaType.APPLICATION_V1XML_TYPE);
m.put("v1-json", CnodbMediaType.APPLICATION_V1JSON_TYPE);
return m;
}
protected static Map<String,Object> createProperties() {
Map<String, Object> properties = new HashMap<String,
Object>();
properties.put(PackagesResourceConfig.PROPERTY_PACKAGES,
"mil.cnodb.rs.resources.v1");
WadlGeneratorConfig config = WadlGeneratorConfig
.generator(WadlGeneratorApplicationDoc.class)
.prop("applicationDocsFile",
"classpath:/application-doc.xml")
.generator(WadlGeneratorGrammarsSupport.class)
.prop("grammarsFile",
"classpath:/application-grammars.xml")
.generator(WadlGeneratorResourceDocSupport.class)
.prop("resourceDocFile", "classpath:/resourcedoc.xml")
.build();
properties.put(ResourceConfig.PROPERTY_WADL_GENERATOR_CONFIG,
config);
return properties;
}
}
And edited web.xml
