JAX-WS客户端：压缩响应不支持MediaException

Question

I wrote JAX-WS (from Sun) client which makes service calls which expect server responses to be gzipped:

Map<String, List<String>> theHeaders = new HashMap<String, List<String>>();
theHeaders.put("Content-Encoding", Collections.singletonList("gzip"));
theHeaders.put("Accept", Collections.singletonList("application/x-gzip"));
theHeaders.put("Accept-Encoding", Collections.singletonList("gzip, deflate"));
theHeaders.put("Content-Type", Collections.singletonList("application/x-gzip"));
((BindingProvider) client).getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, theHeaders);

According to the Fiddler, response is HTTP 200 (Ok) and soap response is gzipped. Still, I'm getting the following error:

com.sun.xml.ws.server.UnsupportedMediaException: Unsupported Content-Type: application/x-gzip Supported ones are: [application/soap+xml]
at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:322)
at com.sun.xml.ws.encoding.StreamSOAP12Codec.decode(StreamSOAP12Codec.java:107)
at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:156)
at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:312)
at com.sun.xml.ws.transport.http.client.HttpTransportPipe.createResponsePacket(HttpTransportPipe.java:295)

I read that JAX-WS should support gzipped webservice responses out of the box, but it looks like it doesn't. It tries to use default codec which is for application/soap+xml despite the fact response contains Content-Type: application/x-gzip header.

Is there a way to make it use another codec, for gzip? Is there such a codec?

Answer 1

The link you referred to is telling that it supports gzip when the response is sent with

Content-encoding: gzip

header, in addition to standard content-type header. If the server responds with Content-Type: application/x-gzip , it's a different header, and it doesn't seem that would be supported even though gzip in itself is supported. I don't think you should be setting this:

theHeaders.put("Accept", Collections.singletonList("application/x-gzip"));

instead, just set accept-encoding including gzip:

theHeaders.put("Accept", Collections.singletonList("application/soap+xml"));
theHeaders.put("Content-Type", Collections.singletonList("application/soap+xml"));
theHeaders.put("Accept-Encoding", Collections.singletonList("gzip"));
theHeaders.put("Content-Encoding", Collections.singletonList("gzip"));
