public static void main(String[] args) throws IOException {
    		String r = AnalysisXML.getXml(); //要传入的xml字符串
    		String path ="http://localhost:8080/axis/services/bxserver";
    		java.net.URL url = new java.net.URL(path);  
    		// 打开连接
            HttpURLConnection connection = (HttpURLConnection) url
                    .openConnection();
            // 设置是否向connection输出，因为这个是post请求，参数要放在
            // http正文内，因此需要设为true
            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setRequestMethod("POST");
            // Post 请求不能使用缓存
            connection.setUseCaches(false);
            connection.setInstanceFollowRedirects(true);
            connection.setRequestProperty("Content-Type",
                    "text/xml");
    		connection.connect(); 
    		DataOutputStream out = new DataOutputStream(connection
                    .getOutputStream());
            out.writeBytes(r); 
            out.flush();  
            out.close();
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    connection.getInputStream()));
            String line;
            System.out.println("=============================");
            System.out.println("Contents of post request");
            System.out.println("=============================");
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            System.out.println("=============================");
            System.out.println("Contents of post request ends");
            System.out.println("=============================");
            reader.close();
            connection.disconnect();
    	}

Servlet中获取流信息：

String resultXml = "";
    		boolean resultStr = true;
    		String XMLData = null;
    		StringBuffer tempStringBuffer = new StringBuffer();
    		String tempString = null; 
    		BufferedReader reader = request.getReader();
    	    while ((tempString = reader.readLine()) != null){
    	        tempStringBuffer.append(tempString);
    	    } 
    	    XMLData = tempStringBuffer.toString();
