how to manager the "managed bean" on jsf in visual web application and another questions

[dreampeppers99]

Using the netbeans when I create a Visual Web Project, have the three perspectives [jsp][java][design].

If put a text field on the center, do this creates a component on Java Perspective.

But I need to convert the .getText().toString() to return an String.

How can I bind a domain object with a component like text field.
And never convert to int, double.

And how can I populate a table using a list?
Can I use another implementation of jsf(like tomahawk) on netbeans?
