Hi Arpana

I could see the following places where the compilation error could occur.

(1) The beginning of the first line is not proper

 %@page language="java" %> 

(2) No imports specified for Vector and Enumeration

(3)

 Public void jspInit() 

'Public' should be 'public'

On correcting all the above the jsp compiles and gives the output
First Value Second Value

Hope I am clear.

Hi Arpana
I think Balamurugan is incorrect.
JSP file gets translated first and then compiled. During translation it checks for correct syntax of all JSP elements. Since the page directive syntax is incorrect, it should generate a translation error (unless it is a typo in your text). So the correct answer should be C. Translation Error

Correct me if I am wrong.
