132 Given the JavaBean class:
public class MyBean {
private Boolean roasted = false;
public MyBean () {}
public Boolean isRoasted () { returned roasted }
public void setRoasted (Boolean roasted) { this.roasted = roasted; ] }
Assume a controller has created an instance of this bean, called setRoasted (true), and inserted the bean into the application scope using the name "myBean".
A JSP contains these two tags:
＜jsp: useBean id = "aBean" class = "MyBean" scope = "page" \ /＞
＜jsp: getProprty name = "aBean" property = "roasted" \ /＞
Which is true?
(A) the page will include the output false
(B) the page will include the output true
(C) the page will report that the property roasted does not exist
(D) the page will report that the syntax of the useBean tag is incorrect
