In Jersey 2.16 file download is very easy

Below is the example for the ZIP file

@GET
@Path("zipFile")
@Produces("application/zip")
public Response getFile() {
    File f = new File(ZIP_FILE_PATH);

    if (!f.exists()) {
        throw new WebApplicationException(404);
    }

    return Response.ok(f)
            .header("Content-Disposition",
                    "attachment; filename=server.zip").build();
}
