this full example to upload image using jersey client and webservice you client code

public class Test {

    private static URI getBaseURI() {
        return UriBuilder.fromUri("http://localhost:8080/restfullwebservice/resources/generic").build("");
    }

    public static void main(String[] args) throws FileNotFoundException {
        final ClientConfig config = new DefaultClientConfig();
        final Client client = Client.create(config);

        final WebResource resource = client.resource(getBaseURI()).path("upload");

        final File fileToUpload = new File("C:/Users/Public/Pictures/Desert.jpg");

        final FormDataMultiPart multiPart = new FormDataMultiPart();
        if (fileToUpload != null) {
            multiPart.bodyPart(new FileDataBodyPart("file", fileToUpload,
                    MediaType.APPLICATION_OCTET_STREAM_TYPE));
        }

        final ClientResponse clientResp = resource.type(
                MediaType.MULTIPART_FORM_DATA_TYPE).post(ClientResponse.class,
                multiPart);
        System.out.println("Response: " + clientResp.getClientResponseStatus());

        client.destroy();
    }
}

your webservice

@POST
@Path("upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void uploadFile(@FormDataParam("file") InputStream uploadedInputStream, @FormDataParam("file") FormDataContentDisposition fileDetail) throws ServiceChannelException {
    OutputStream os = null;
    try {
        File fileToUpload = new File("C:/Users/Public/Pictures/Desert1.jpg");
        os = new FileOutputStream(fileToUpload);
        byte[] b = new byte[2048];
        int length;
        while ((length = uploadedInputStream.read(b)) != -1) {
            os.write(b, 0, length);
        }
    } catch (IOException ex) {
        Logger.getLogger(GenericResource.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        try {
            os.close();
        } catch (IOException ex) {
            Logger.getLogger(GenericResource.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}
