Convert InboundJaxrsResponse to json string

I am trying to serialize a jax-rs Response to json string.

The response from the server is json, and I get it from jersey client with:

Response resp = target.request().method("PUT", Entity.json(payloadBean))

where payloadBean is my json request. Everything works fine but I cannot convert the resp in json string in order to log it.

If I try:

String s = EntityUtils.toString((HttpEntity) resp.getEntity());

I get: 

org.glassfish.jersey.client.internal.HttpUrlConnector cannot be cast to org.apache.http.HttpEntity

By the way if I don't cast to HttpEntity, compiler says:

toString (org.apache.http.HttpEntity) in EntityUtils cannot be applied to (java.lang.Object).

My relevant imports are:

import org.apache.http.HttpEntity;
import org.apache.http.util.EntityUtils;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Response;

Any ideas?

Finally I needed to buffer the message entity data since the stream was consumed and I was getting an error later when I was trying to re-read the response. Thus in order to log it first and then use it again I had to:

resp.bufferEntity();  //need to buffer entity, in order to read the entity multiple times from the Response's InputStream
String s = resp.readEntity(String.class);

Use resp.readEntity(String.class)

public abstract <T> T readEntity(Class<T> entityType)

Type Parameters: T - entity instance Java type.

Parameters: entityType - the type of entity.

Read the message entity input stream as an instance of specified Java type using a MessageBodyReader that supports mapping the message entity stream onto the requested type.
