Hi Chuck, I send you a sample code where a resource generates a representation according to the file extension. It doesn't rely on a Filter, but seems to work. the code illustrate 2 cases, the first one where the Resource knows the mappings between extensions and metadata, the second one where the resource relies on the parent application metadataService:
**************************
// Case 1 - without the Application metadata service
if ("js".equals(ext)) {
getVariants().add(new Variant(MediaType.APPLICATION_JSON));
} else if ("xml".equals(ext)) {
getVariants().add(new Variant(MediaType.APPLICATION_ATOM_XML));
} else {
// What you want, even let the Variants set empty (will return 404
// response)
getVariants().add(new Variant(MediaType.TEXT_PLAIN));
}
// Case 2 - uses the Application metadata service
Application application = (Application) context.getAttributes().get(
Application.KEY);
Metadata metadata = application.getMetadataService().getMetadata(ext);
if (metadata != null && metadata instanceof MediaType) {
getVariants().add(new Variant((MediaType) metadata));
} else {
// What you want, even let the Variants set empty (will return 404
// response)
getVariants().add(new Variant(MediaType.TEXT_PLAIN));
}
**************************
I hope this will help you.
Best regards,
Thierry Boileau
