Problems connecting Netbeans IDE to MS SQL Server database

I am operating a Windows 7 Home Premium OS with successfully installed MS SQL Server 2005 and Netbeans version 7.0 beta. Everything is working properly without any problem in software. I want to develop a Java project which is to be connected to a MS SQL Server database.
I am facing a problem that the Netbeans IDE is unable to connect with MS SQL Server database. The databases Node is shown in the Services Window when I click it, SQL Server is not shown but I can see Java DB database. I have registered the JDBC driver for MS SQL Server with Netbeans, but still I don't know how to connect to the database.
