Check whether remote server is accessible

Hi All,

I am parsing a WSDL from a remote server. If I have access to that server, I can do it very comfortably.

How do I put a validation like whether that Server is accessible to me. I saw a few examples like the one listed below (where I try to check whether echo port is accessible)

try {
Socket t = new Socket("<servername>", 7);
DataInputStream dis = new DataInputStream(t.getInputStream());
PrintStream ps = new PrintStream(t.getOutputStream());
ps.println("Hello");
String str = dis.toString();
if (str.equals("Hello"))
System.out.println("Alive!") ;
else
System.out.println("Cannot Connect to Server");
t.close();
} catch (Exception e) {
e.printStackTrace();
}

I want to throw an Error message if I am unable to read the file on remote server. Also do I need specify the complete path (along with filename) while checking for the accessibility.

Cheers!!!
Ronnie
