Pls [sic] some help

Did you read the links I suggested?

You don't use explicit code like that to retrieve values. You do it by
binding your "value" attribute to a backing bean property, which bean is
specified in the faces-config.xml. JSF does the mapping for you.

Read the part about the JSF life cycle in the tutorial. Study it thoroughly.
Let us know that you've read the material before you repeat your questions
again. Then if you have specific questions about the material you can ask
them based on your reading, which you must do first.
