REST Token based Authentication not working

I am trying to implement Token based authentication in java RESTful web service.

So far I have done following things 1) Created NameBinding secured

@NameBinding @Retention(RetentionPolicy.SOURCE) @Target({ElementType.TYPE, ElementType.METHOD}) public @interface Secured { } 

2) Created a authentication filter

@Secured @Provider @Priority(Priorities.AUTHENTICATION) public class AuthenticationFilter implements ContainerRequestFilter { @Override public void filter(ContainerRequestContext requestContext) throws IOException { // Get the HTTP Authorization header from the request String authorizationHeader = requestContext.getHeaderString(HttpHeaders.AUTHORIZATION); // Check if the HTTP Authorization header is present and formatted correctly if (authorizationHeader == null || !authorizationHeader.startsWith("Bearer")) { throw new NotAuthorizedException("Authorization header must be provided"); } // Extract the token from the HTTP Authorization header String token = authorizationHeader.substring("Bearer".length()).trim(); try { // Validate the token validateToken(token); } catch (Exception e) { requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED).build()); } } private void validateToken(String token) throws Exception { // Check if it was issued by the server and if it's not expired // Throw an Exception if the token is invalid } 

3) Now When I am trying to put secured annotation on my service method somehow it is not working and correct json is returned.

@GET @Secured @Path("{custid}/invoices") @Produces({"application/json"}) @Consumes({"application/x-www-form-urlencoded"}) public List<Document> getCustomerInvoices( @PathParam("custid") String account, @DefaultValue("") @QueryParam("fromdate") String fromDate, @DefaultValue("") @QueryParam("todate") String toDate) throws Exception{ Date from = null; Date to = null; SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); if(!fromDate.equals("")) { from = formatter.parse(fromDate); } if(!toDate.equals("")) { to = formatter.parse(toDate); } ArrayList<Document> invoices = (ArrayList<Document>) CustomerBiz.getInvoices(documentumConfigUtil,DocumentType.TAX_INVOICE,account,from,to); return invoices; } 

Please suggest me where I am doing wrong.

Note: I have used Apache CXF and spring to create java web service.
