Exception Handling for failed connection

[jmorr212]

Hello again, i have this code working fine.

sR = (HttpsURLConnection)daLogin.openConnection();          
            sR.setRequestProperty("Authorization",
            "Passport1.4 OrgVerb=GET,OrgURL=http%3A%2F    %2Fmessenger%2Emsn%2Ecom,sign-in=" +
            uN.replaceAll("@", "%40") + ",pwd=" + pW+ "," + cS);

The only problem is the exception handling, this connects to the msn server. If the username(uN) or password(pW) are incorrect, i want it to throw some form of exception so that the next few lines or code are not executed. I am unsure of such an exception though? I can use getResponseCode() to see whether its 200(authorized) 401(unauthorized) but even if it returns 401 it doesnt throw any error. I tried HTTPException and it didnt work..

thanks,

So far im using

int errorCode = sR.getResponseCode();
if(errorCode == 200)
{
 //do stuff here
}
else{}//when its 401 do nothing

I would like to know a more efficient way though.
