Place the code snippets in the proper order to construct the JSP code to import static content into a JSP page at translation-time.
4. Your web application views all have the same header, which includes the <title> tag in the
< head> element of the rendered HTML. You have decided to remove this redundant HTML code from your JSPs and put it into a single JSP called /WEB-INF/jsp/header.jsp.
However, the title of each page is unique, so you have decided to use a variable called pageTitle to parameterize this in the header JSP, like this:
10. <title>${param.pageTitle}<title>
Which JSP code snippet should you use in your main view JSPs to insert the header and pass the pageTitle variable?
A) <jsp:include page='/WEB-INF/jsp/header.jsp'>
$ {pageTitle='Welcome Page'}
< /jsp:include>
B) <jsp:insert page='/WEB-INF/jsp/header.jsp'>
< jsp:param name='pageTitle' value='Welcome Page' />
< /jsp:insert>
C) <jsp:insert page='/WEB-INF/jsp/header.jsp'>
$ {pageTitle='Welcome Page'}
< /jsp:insert>
D) <jsp:include page='/WEB-INF/jsp/header.jsp'>
< jsp:param name='pageTitle' value='Welcome Page' />
< /jsp:include>
E) <jsp:include file='/WEB-INF/jsp/header.jsp'>
$ {pageTitle='Welcome Page'}
