Jersey Client API - Getting JavaIOException premature EOF when consuming a service

Question

I'm using Jersey to implement my webservices. I'm creating a java Client that will consume these services based on Jersey Client API. When I call a webservice that resturns a list of String, a map or a business object ALL is OK and I get the expected response in my client side. However, when calling a webservice returning a String or an int, I get JavaIOException: premature EOF. Do you have any idea about this issue please?

I'm instantiating my client in this way :

String serviceUrl = "http://localhost:9998";
ClientConfig config = new DefaultClientConfig();
config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
Client client = Client.create(config);
resource = client.resource(serviceUrl + "/infos");
resource.accept(MediaType.APPLICATION_JSON_TYPE);

The Method I'm calling should return a String :

public String getInfo() {
    return resource.get(String.class);
}

Here is the error stackTrace :

Answer 1

Also may be you are call the response.getEntity] more than one time that mean you will call closed stream , as the Closeable reader will be closed from first call. So just call response.getEntity then use the entity to get resource values.
