Hi, I'm using Hibernate to connect to an SQL Server 2008 named instance.
This works if I use the default instance name but not when using the "named" instance.
config.setProperty("hibernate.connection.url","jdbc:sqlserver://127.0.0.1\INSTANCE_NAME:1433;databaseName=DB_NAME;autoReconnect=true");

Thanks i...
