I don't know how to connect (string connection) to a SQL Server 2005 db from NetBeans. I'm posting some of the database properties taken from SQL Server Management Studio Express:
Server name ACER-1155CCFAC6/NetSDK
Instance name NETSDK
How is the connection string in this case?
This information is useless.
if you're still having trouble post the code you tried so that we can at least see that you've amde an effort.
