Mock Exam Question:
A JSP page has the following useBean declaration that references a bean called Person. The person class has a private field calledfirstname and an appropriate getter (accessor) method for retrieving the value of that field.<jsp:useBean id="person" type="com.examulator.Person" class="com.examulator.Person" scope="session" />Which of the following is the correct syntax for a getProperty tag to retrieve the value of the instance of Person.
a)<jsp:getProperty name="person" property="firstname"/>
b)<jsp:getProperty name="person" property="getFirstname"/>
c)<jsp:getProperty id="person" property="firstname"/>
d)<jsp:getProperty name="person" property="firstname" class="com.examulator.Person"/>
e)<jsp:getProperty name="person" property="firstname" scope="session"/>
a. a
b. b
c. c
d. d
e. e

I answered e, but mock result gives me option a, since in usebean they have mentioned scope as session i think while getting the value we have to put scope attribute.. Correct me if iam wrong

getProperty can never contain scope attribute.
Farmers know to never drive a tractor near a honey locust tree. But a tiny ad is okay:
