run the command 'telnet localhost 1521' on the command prompt where the database is running.
As you have said it is windows vista, 'telnet' may not work by default enable it by going to control panel and 'programs and features'.

if 'telnet localhost 1521' works then it is sure that your program should work.

It is like a specification where the implementors has to carry out.

any implementor can implement in his own way sticking to the contract.
