JSP query! Can anyone give solution for this

[srinivas pola]

Question: For manageability purposes, you have been told to add a "count" instance
variable to a critical JSP Document so that a JMX MBean can track how frequent this JSP is being
invoked. Which JSP code snippet must you use to declare this instance variable in the JSP Document?

A. <jsp:declaration>
int count = 0;
<jsp:declaration>
B. <%! int count = 0; %>
C. <jsp:declaration.instance>
int count = 0;
<jsp:declaration.instance>
D. <jsp:scriptlet.declaration>
int count = 0;
<jsp:scriptlet.declaration>

The answer for the above question was given as 'A' in the mock exam paper. But i think 'B' is the right answer.
Can anyone help me solve this?
Thanks in advance.

Hi Srinivas,
In the question, it is mentioned that "add a "count" instance
variable to a critical JSP Document so that........" .

A JSP document is a JSP page written in XML syntax as opposed to the standard syntax. As per the standard syntax...option B is correct. Here we need to look for the XML syntax as it is mentioned as a JSP document. Hence Option A is correct.

Hope this helps.

Hi,

The Question is asked about JSP Document.

It means jsp is XML complaint. So it should be <jsp:declaration> </jsp:declaration>

it should not be<! int a=0;%>, this is not xml complaint.

Thanks,
