To verify that the Derby Network Server is currently running, use the ping command.
You can use the ping command in the following ways:
private static boolean isServerStarted(NetworkServerControl server, int ntries)
{
for (int i = 1; i <= ntries; i ++)
{
try {
Thread.sleep(500);
server.ping();
return true;
}
catch (Exception e) {
if (i == ntries)
return false;
}
}
return false;
}
