安卓开发 调用java写的jax-ws 格式的webservices

public static final String NAME_SPACE = "http://webService.sxthnet/";
public static String URL = "http://100.123.68.166:8080/wbs1/Server1Port";

@Override

ed1.setText("bkkd");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
SoapObject request = new SoapObject(NAME_SPACE,Method2);
//传递参数必须是arg开头，//写真实的变量名也没有用，必须是　arg0 ,arg1 一直排下去，好像只支持10个参数．//其他人说的都弱毙了
request.addProperty("arg0", "张木生" );

// request.addProperty("username", "我的" );

if(envelope.getResponse()!=null){

}
else
ed1.setText("No");
} catch(Exception e){ 
System.out.println(e.toString());
e.printStackTrace();
ed1.setText(e.toString());
