4. You have a use case in your web application that adds several session-scoped attributes. At the end of the use case, one of these objects, the manager attribute, is removed and then it needs to decide which of the other session-scoped attributes to remove.
How can this goal be accomplished?
A) The object of the manager attribute should implement the HttpSessionListener and it should call the deleteAttribute method on the appropriate session attributes.
B) The object of the manager attribute should implement the HttpSessionListener and it should call the removeAttribute method on the appropriate session attributes.
C) The object of the manager attribute should implement the HttpSessionBindingListener and it should call the deleteAttribute method on the appropriate session attributes.
D) The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes.
5. 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'> <jsp:param name='pageTitle' value='Welcome Page' /> </jsp:include>
B) <jsp:insert page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:insert>
C) <jsp:insert page='/WEB-INF/jsp/header.jsp'>
<jsp:param name='pageTitle' value='Welcome Page' />
</jsp:insert>
D) <jsp:include page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include>
E) <jsp:include file='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include>
