I am running a tool which just makes connection and closes it (using JDBC)
.. The JDBC connection never says 'Can not establish connection' .. I just
says ' at this time ' took 70 secs to establish a connection .. So my
guess was network was not a problem,( since connection was established but
takes extra time ) .. The application says 'Can not establish connection'
=> cant establish connection in a specified timeout..
Am i guessing anything wrong or can I get any ideas please ?
