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:
