Greetings.
I would appreciate guidance regarding review question # 6 from Chapter 13 - Reusable Web Components in the book SCWCD Exam Study Kit by Hanumant Deshmukh and Jignesh Malavia.
What I do not understand is how the red and green param values appear in the colors array.
The question is as follows:
File 1: this.jsp
html body pre
jsp:include page="that.jsp"
jsp
aram name="color" value="red" /
jsp
aram name="color" value="green" /
/jsp:include
/pre /body /html
File 2: that.jsp
%
String colors[] = request.getParameterValues("color");
for (int i=0; i<colors.length; i++)
{
out.print(colors[i] + " ");
}
%
What will be the output of accessing the this.jsp file via the following URL?
http:/localhost:8080/chapter13/this.jsp?color=blue
The answer is: red green blue
Explanation
The parameters passed via the <jsp
aram> tag to an included component tag take precedence over the parameters already present in the request object of the including component. Also, the order of values passed via the <jsp
aram> tag is the same as the order in which the tags appear. Thus, the correct answer is c. The output will be red green blue.
Thank you in advance for your assistance.
