使用HttpClient 4.1.2调用webservice
下载httpclient，把压缩包里lib目录的所有jar放到项目的编译目录里，
通过Post方式调用webservice，代码如下：

import java.io.IOException;import java.io.UnsupportedEncodingException;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.methods.HttpPost;import org.apache.http.entity.StringEntity;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.protocol.HTTP;import org.apache.http.util.EntityUtils;public class HttpclientSoap {public static void main(String[] args){DefaultHttpClient httpClient = new DefaultHttpClient();String soapRequestData = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +"<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">"  +  "<soap12:Body>" +   " <SetData xmlns=\"http://tempuri.org/\">" +     " <dz>宁波海曙市</dz>" +    "  <id>27000</id>" +    "  <xx>27000</xx>" +    "  <yy>13112</yy>" +    "  <bui_id>4209</bui_id>" +    "  <mc>天一数码</mc>" +    "</SetData>" + " </soap12:Body>" +"</soap12:Envelope>" ;HttpPost httppost = new HttpPost("http://localhost/Service1.asmx");/*把Soap请求数据添加到PostMethod*///byte[] b = soapRequestData.getBytes("utf-8");//InputStream is = new ByteArrayInputStream(b,0,b.length);try {HttpEntity re = new StringEntity(soapRequestData,HTTP.UTF_8);httppost.setHeader("Content-Type","application/soap+xml; charset=utf-8");//httppost.setHeader("Content-Length", String.valueOf(soapRequestData.length()));httppost.setEntity(re);HttpResponse response = httpClient.execute(httppost);System.out.println(EntityUtils.toString(httppost.getEntity()));System.out.println(response.getStatusLine());System.out.println(EntityUtils.toString(response.getEntity()));} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (ClientProtocolException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}finally{httpClient.getConnectionManager().shutdown();}}}
