需要jar包：

commons-logging-1.0.4.jar
httpclient-4.3.2.jar
httpcore-4.3.2.jar

測試：

package http;

public class TestSoap {
    public static void main(String[] args) {
        String soapXml="<?xml version=\"1.0\" encoding=\"utf-16\"?>" +
                "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org
 
/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +
                "  <soap:Body>" +
                "    <execute xmlns=\"webservices.wst.weaver.com.cn\">" +
                "      <in0>wer</in0>" +
                "      <in1
 
>2</in1>" +
                "    </execute>" +
                "  </soap:Body>" +
                "</soap:Envelope>";
        String result=HttpToSoap.doPostSoap("http://127.0.0.1:8087//services/WebServicesTest", soapXml, "", HttpToSoap.soap);
        System.out.println(result);
    }
}
