Using bean in JSF

I am using Sun Java Studio Creator Update 2 for developing JSF web
apps. I want to display a table (datatable) that gets it row data
from
a bean/java class that connects to the database using JDBC and gets
the rows from a table.
I know one way to display database table data is using data provider
from Server tab and bind the table to the row source. But I don't
want
to use visual tools for database connectivity, just use a business
logic bean like we use in simple JSP.
Please help....
