XML : Upload XML/CSV File using Rest Api in java

I just ask for help from the nearby comunity on StackOverflow upload XML or CSV file using the REST API in Java .

URL :

  Remote Address:127.0.0.1:8080  Request URL:http://localhost:8080/HSMV5/api/import  Request Method:POST    

Request Playload :

  ------WebKitFormBoundaryTnLhEykB6lreFMtz  Content-Disposition: form-data; name="aaaa.xml"; filename="aaaa.xml"  Content-Type: text/xml      ------WebKitFormBoundaryTnLhEykB6lreFMtz--    

here is my source code:

  @Path("/")  @Produces(MediaType.APPLICATION_JSON)  @Consumes({ MediaType.APPLICATION_JSON, MediaType.MULTIPART_FORM_DATA })  public class Dispatcher {      @POST      @Path("/import")      public Response importpostFile(              @FormDataParam("file") InputStream uploadedInputStream,              @FormDataParam("file") FormDataContentDisposition fileDetail)              throws HsmRestServiceException {          System.out.println(fileDetail.getFileName());          return importFile.doPost(null);      }    }    

at compile variables returns null :

  uploadedInputStream : null  fileDetail : null
