I installed an SQL Server Express 2008 on my local PC (Window XP SP3). I downloaded sqljdbc4.jar to Crystal Reports for Eclipse
IDE library path and tried to Test Connection, but got the Ping failed message : The TCP/IP connection to the host localhost, port 1433 has failed. It said that check that an instance of SQL Server is running on the host (I saw SQL Server SQLEXPRESS is Running on my PC) and accepting TCP/IP connection at the port (I enabled TCP/IPin my PC's SQL Server Network Configuration),
and that no firewall is blocking TCP connection to the port(I turned OFF Window Firewall on my OC). Can anyone tell me how can I fix this problem ?
