JSP annotations and character reference conventions

JS below are some special tags or characters that you can use to insert notes or characters that may be considered to have special meanings. Grammatical use
<%--Comment--%> jsp annotations, also known as "hidden annotations." The JSP engine ignores it. All JSP script elements, directives, and actions within the tag will not work.
The!--comment--> html annotations, also known as "output annotations," appear directly in the resulting HTML document. All JSP script elements, instructions, and actions within the tag are performed correctly.
<\% in the template text (static HTML) where you actually want the "<%" to appear.
%\> in the script element where you actually want the "%>" to appear.
\ ' Use single quotes within the properties of single quotes. However, you can use either single or double quotes, while another one will have a common meaning.
\ "Use double quotes within the properties of double quotes." See the description of "\".
