Network is unreachable

[Cristian Popovici]

Hello guys,

I have a standalone application tha gathers some data and loads it into the database. The application is running on a pc that changes its IP from hour to hour. After the ip is changed all my jdbc requests are giving a

  
java.net.SocketException
MESSAGE: Network is unreachable

Any ideas?

Thanks.

Do you create a connection pool or keep a connection across the IP change? My gut feeling is that the connection is not valid after the IP change for whatever reason (session with db is invalid, underlaying network socket closed and so on). If this is not an interactive program you could probably get away with creating the connection each time you update the data. You could also talk to your network administrator and try to convince him that you need a static ip address.
