Home JAX-RS Mixing @FormParam and MultivaluedMap<String, String> formParams
 I've a method that returns all records sons of a father record (document and rows for example): public Datasource getSonsFromParent( @FormParam(value = "idparent") Long idparent, MultivaluedMap formParams) throws Exception;  I've a well known parameter, "idparent". I want to get this parameter simply using @FormParam . It's useful for exposing this method to other people: they know that a "idparent" is required. Also, I have a number of undefined parameters for sorting and filtering my datasource, for example sort[0]=name sort[1]=surname filter[0][field]=name filter[0][operator]=equal filter[0][value]=Marc The problem is : using @FormParam, the multivalue map is always empty. How can i mix MultivaluedMap and @FormParam together ?
