Think of the order of operation.
Client asks for test1.jsp. A bean (foo.myBean) is instantiated and held in
the session, there is no name request paramter so the name value of the bean
is not updated.
The client clicks on submit, this passes a name=xxx parameter to test2.jsp,
which access the bean created in test1.jsp, where the name was initialised
in the constructor,
