Thank you for replying, Aravind!
Also interesting - I had a LoggingFeature added to the JAXRSClientFactoryBean
with which I set up the web service. I removed that (and removed the stream
cache enabling to get back to starting point). With that, I can get a Response
into my handler after invoking the service, but trying to read the response
entity as:
String body = wsResponse.readEntity(String.class);
I get an exception:
javax.ws.rs.client.ResponseProcessingException: Problem with reading the data,
class java.lang.String, ContentType: application/json;charset=UTF-8.
