please, this is y concern: I'll like to know how to query a web service defined as in the below code using postman for test purposes. PS: I can't change the method signature
I have a web service like this :
@POST
@Path("/uploadOpenAccountRequestFiles/{requestId}")
@Consumes({MediaType.APPLICATION_JSON,MediaType.MULTIPART_FORM_DATA})
public Response uploadOpenAccountRequestFiles(@PathParam("requestId") String requestId,
        MultipartFormDataInput multipartFormDataInput)
        throws JsonGenerationException, JsonMappingException, IOException {
    initContext();
    logger.info("DIGIBANK : uploadOpenAccountRequestFiles END: ");
    String msge = "";
    try {
        digiBean.saveToserver(requestId, multipartFormDataInput);
    } catch (Exception e) {
        msge = e.getMessage();
        e.printStackTrace();
    }
    org.af.webservice.Response resp = new org.af.webservice.Response(
            request.getSession().getId(), "uploadOpenAccountRequestFiles", "",
            msge.equalsIgnoreCase("OK") ? true : false, msge.equalsIgnoreCase("OK") ? false : true, "",
            msge.equalsIgnoreCase("OK") ? true : false, "Boolean", msge);
    logger.info("DIGIBANK : uploadOpenAccountRequestFiles END: ");
    return Response.ok().entity(mapper.writeValueAsString(resp)).build();
}
this is are images of my configurations:
