Hi Mark,
You have not configured your web.xml correctly to use your own
extension of PackagesResourceConfig.
I do not know what the package name of your class
CnodbRestResourceConfig is, but for the sake of example and clarity i
am going to assume it is "mil.cnodb.rs". The servlet declaration
requires just the following init-param:
<init-param>
<param-
name>com.sun.jersey.config.property.resourceConfigClass</param-name>
<param-value>mil.cnodb.rs.CnodbRestResourceConfig</param-value>
</init-param>
Plus in your CnodbRestResourceConfig you do not require all the WADL
configuration stuff as copied from the camel web example, i dunno if
you are using that or not. You just require the following:
public class CnodbRestResourceConfig extends
PackagesResourceConfig {
public CnodbRestResourceConfig() {
super("mil.cnodb.rs.resources.v1");
}
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;
}
}
Paul.
