如何在Java中Ping WSDL

Question

如何在Java中爲我的WSDL執行Ping？

我已經嘗試過這樣的：

InetAddress.getByname(my_wsdl).isReachable(3000); 

，但沒有奏效。

試試這個

private boolean isWSDLAvailable(String wsdlAddr) { 
     HttpURLConnection c = null; 
     try { 
      URL u = new URL(wsdlAddr); 
      c = (HttpURLConnection) u.openConnection(); 
      c.setRequestMethod("HEAD"); 
      c.getInputStream(); 
      return c.getResponseCode() == 200; 
     } catch (Exception e) { 
      return false; 
     } finally { 
      if (c != null) c.disconnect(); 
     }  
}
