If I insert a line
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> to the beginning of the jsp file
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="description" content="library"> <meta name="author" content="me"> then in the browser the entire jsp is displayed simply with text with all the tags.
jstl does not work either, they are also displayed simply with text, for example, "$ {PERSONS}" here is pom.xml:
