Ping Server Status & Action

[Tarun Trehan]

Hi All,

I have a blog site for which i need to check the status and send an alert if the blog is not up and running.
I need to repeat this task every 30 minutes(configurable in code). Though i have couple of other questions which i can come to later; my initial one is that:
"If the server has not been started/not responding , there is problem and i should get a notification/alert for it.
I wrote the java code for this. However, whenever the server is not started, i do not get a proper response code; instead i get a "Connect Exception".
Hence, i have to call the alert/notification code from an exception."
Is that correct (to initiate a business scenario from a catch block) or am i missing something here ??

Following are some code snippets.

private static void sendGet(String c) {
		try {
			URL obj = new URL(url);
			HttpURLConnection con = (HttpURLConnection) obj.openConnection();
			con.setRequestMethod(requestMethod);
			System.out.println(con.getInputStream());
			int responseCode = con.getResponseCode();
                        // If the server is up, i get 200 as response code. However, if its not up, it gives a exception and i am looking for a code.
			System.out.println("Response Code : " + responseCode);
		} catch (ConnectException e) {
			System.out.println("ALERT Now");
			// Is it ok to process some business logic from catch block ????
                        alertOwners();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}


// Code to send alert/notification. Skipping the description of this code.
private static void alertOwners()
	{
		
	}
