send a form parameter from Chrome Advanced REST Client

Question

I want to send a form parameter from Chrome Advanced REST Client, however, it comes as null. This my resource class

IKeywordResource.java

@Path("")
public interface IKeywordResource {

    @POST
    @Path("/upload")
    @Consumes("multipart/form-data")
    public List<Keyword> uploadKeywords(MultipartFormDataInput uploadFile,
                                        @FormParam("list_format") String listFormat) throws IOException;
}

KeywordResource

public class KeywordResource implements IKeywordResource {

    @Inject
    public KeywordService keywordService;


    @Override
    public List<Keyword> uploadKeywords(MultipartFormDataInput uploadFile,
                                        @FormParam("list_format") String listFormat) throws IOException {

        return keywordService.upload(uploadFile, listFormat);
    }
}

And this is how I send the POST request and define the form parameter.

However, as I said list_format comes as null that I dont know why. I will appreciate for any kind of help

You are trying to map the request payload twice. You can either map all parameters to a MultipartFormDataInput object and retrieve your parameter with uploadFile.getFormDataMap().get("list_format"); or you map each parameter with @FormParam.
