			//將響應的訊息轉換為dom物件
			Document doc = responseMessage.getSOAPPart().getEnvelope().getBody().extractContentAsDocument();

			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block

得到結果：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><xsd:add xmlns:xsd="http://soap.lichen.cn/"><a>50</a><b>34</b></xsd:add></SOAP-ENV:Body></SOAP-ENV:Envelope>

-----------invoking-------------

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Header/><S:Body><ns2:addResponse xmlns:ns2="http://soap.lichen.cn/"><addResult>84</addResult></ns2:addResponse></S:Body></S:Envelope>
