8.1 Write the opening and closing tags for the following JSP tag types:
Directive
Declaration
Scriptlet
Expression
8.2 Given a type of JSP tag, identify correct statements about its purpose or use.
8.3 Given a JSP tag type, identify the equivalent XML-based tags.
8.4 Identify the page directive attribute, and its values, that:
