    The @HeaderParam annotation allows you to map a request HTTP header to your method invocation.


    GET /books?num=5


       public String getBooks(@HeaderParam("From") String from) {


    Like PathParam, your parameter type can be an String, primitive, or class that has a String constructor or static valueOf() method.  For example, MediaType has a valueOf() method and you could do:


       public void put(@HeaderParam("Content-Type") MediaType contentType, ...)
