Dear eclipse jersey users,
I have a jersey v2.30 application using jersey-container-grizzly2-http and jersey-grizzly-connector. I have an endpoint which returns a pdf file, the endpoint seems to work which means the client gets the file successfully, however on the server side I can see the exception below.
From google seems like this error means the client is closing the connection and I would like to dig a little bit more and understand why is doing that and what can I do to stop this from happening.

This is my code:
@POST
@Path("/au/last-mile-label")
@Consumes(MediaType.APPLICATION_JSON)
@Produces("application/pdf")
public Object postLastMileAu(UberShipment shipment) {
EntityManager em = MyPonyApp.emf.createEntityManager();
// get carrier API provider
String carrier = "AUPostApi";
Response response = CarrierApiFactory.carrierApiMapping.get(carrier)
.createDomesticShipmentAndCreateAndGetLabelLastMile(
em,
shipment);
em.close();
return response;
}
@Override
public Response createDomesticShipmentAndCreateAndGetLabelLastMile(EntityManager em, UberShipment uberShipment) {
String shipmentId = this.createShipment(em, uberShipment, uberShipment.getLastMileOrigin(), uberShipment.getLastMileDestination());
uberShipment.setCarrierRefFrontMile(shipmentId);
String request_id = this.createLabel(em, uberShipment, null, null);
return this.getLabel(em, request_id);
}
public Response getLabel(EntityManager em, String request_id) {
...
return getLabelFromUrl(jsonNode.get("labels").elements().next().get("url").textValue());
}
private Response getLabelFromUrl(String url) {
Client client = ClientBuilder.newClient()
.register(MultiPartFeature.class)
.register(new LoggingFeature(Logger.getLogger(LoggingFeature.DEFAULT_LOGGER_NAME), Level.INFO, null, null));
client.property(ClientProperties.CONNECT_TIMEOUT, 2000);
client.property(ClientProperties.READ_TIMEOUT, 20000);
Invocation.Builder req = client.target(url)
.request()
.header("client_id", api_key);
Response response = req.get(Response.class);
return response;
}
Any advice would be highly appreciated
thank you
