how can i check that a page is up?

Hi in the past i was using the followng code below to check if a
server was up and if it was to call a jsp...
However the jsp now resides to my server so there is no point really
of chekcing if it is up to call it ..
So how can i check that the specific page

e.g http://server.com:8100my.jsp
is up??  (resouces / snip of code
please)

 try {

            InetAddress address =
InetAddress.getByName("servername.com");

            System.out.println("Name: " + address.getHostName());



            System.out.println("Addr: " + address.getHostAddress());

            System.out.println("Reach: " + address.isReachable(3000));


call url ....
}

 } catch (UnknownHostException e) {

            System.err.println("Unable to lookup the sic app");



            mySession.getVariableField(IProjectVariables.TEMP)

                        .setValue("error");

      } catch (IOException e) {

            System.err.println("Unable to reach the sic app");

            mySession.getVariableField(IProjectVariables.TEMP)

                        .setValue("error");



      }
