Dan, You are mixing up non-blocking i/o transport and a blocking i/o entity implementation. This is generally a bad idea as it cannot be done efficiently without full or partial content buffering in memory. If do not mind buffering the entire entity in memory, you can replace --- response.setEntity(responseEntity); --- with --- final ByteArrayOutputStream out = new ByteArrayOutputStream(); responseEntity.writeTo(out); response.setEntity(new ByteArrayEntity(out.toByteArray())); --- and your code will work just fine.
