webservice实现有多种方式

比如最常用的有axis框架，xfire框架，通过该框架可以发布wsdl接口，也可以实现webservice客户端，目前eclipse都有集成的插件，可以根据wsdl文件生成webservice客户端调用接口，但是这样部署的时候必须依赖框架的jar包，有时候可能因为环境等等原因，我们仅仅需要wsdl中的某一个接口，这时候可以通过http接口或socket接口直接发生xml数据，来调用服务端webservice服务，其实webservice底层还是发送xml数据，只是框架封装了对xml数据进行序列化与反序列化操作，下面以两个简单的例子说明http方式和socket方式。

http实现webservice接口调用例子：

1. import java.io.BufferedReader;  
2. import java.io.IOException;  
3. import java.io.InputStreamReader;  
4. import java.io.OutputStreamWriter;  
5. import java.io.UnsupportedEncodingException;  
6. import .MalformedURLException;  
7. import .URL;  
8. import .URLConnection;  
9.   
10. public class
11. void
12. try
13. new
14.             URLConnection con = url.openConnection();  
15. true);  
16. "Pragma:", "no-cache");  
17. "Cache-Control", "no-cache");  
18. "Content-Type", "text/xml");  
19.               
20. out = new
21.             String xmlInfo = getXmlInfo();  
22. out.write(new
23. out.flush();  
24. out.close();  
25. new BufferedReader(new
26. "";  
27. new
28. for (line = br.readLine(); line != null; line = br.readLine()) {  
29. new String(line.getBytes(),"UTF-8"));  
30.             }  
31. out.println(buf.toString());  
32. catch
33.             e.printStackTrace();  
34. catch
35.             e.printStackTrace();  
36.         }  
37.     }  
38.   
39. private
40. // 通过wsdl文件可以查看接口xml格式数据，构造调用接口xml数据
41. "<SOAP-ENV:Envelope xmlns:SOAP-ENV=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:SOAP-ENC=/"http://schemas.xmlsoap.org/soap/encoding//" xmlns:xsi=/"http://www.w3.org/2001/XMLSchema-instance/" xmlns:xsd=/"http://www.w3.org/2001/XMLSchema/">"
42. "<SOAP-ENV:Body>"

55. "</m:getItemDetailSingle>"
56. "</SOAP-ENV:Body>"
57. "</SOAP-ENV:Envelope>";  
58. return
59.     }  
60.   
61. public static void
62. "http://localhost:9003/dataService/services/Job";
