xfire调用webservice[#document: null]问题

xfire 调用.net webservice的时候返回[#document: null]这个事怎么回事呀？

Client client = new Client(

new URL(

"http://www.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx?wsdl"));

HttpClientParams params = new HttpClientParams();

params.setParameter(HttpClientParams.USE_EXPECT_CONTINUE,

Boolean.FALSE);

params.setParameter(HttpClientParams.CONNECTION_MANAGER_TIMEOUT,

(long) 9000);

client.setProperty(CommonsHttpMessageSender.HTTP_CLIENT_PARAMS,

params);

Object[] obj = (Object[]) client.invoke("getCountryCityByIp", new Object[] {

"125.64.15.45" });

返回的是org.apache.xerces.dom.DocumentImpl,你也可以强制转换为w3c的document。

java操作xml:

try {

Client client = new Client(new URL("http://www.webxml.com.cn/webservices/ChinaTVprogramWebService.asmx?wsdl"));

Object[] results = client.invoke("getTVchannelString",new Integer[]{2});

System.out.println(results[0]);

Document d = (Document)results[0];

System.out.println(d.getFirstChild());

NodeList nl =d.getElementsByTagName("getTVchannelStringResult");

NodeList n2 = nl.item(0).getChildNodes();

System.out.println(n2.getLength());

for (int i=0;i<n2.getLength();i++){

System.out.println(n2.item(i).getNodeName()+"::"+n2.item(i).getTextContent());

}

} catch (MalformedURLException e) {

e.printStackTrace();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}
