Hello there, first time poster here. I hope I am in the right list.
I am trying to learn JSTL, when reading this tutorial I get the below line that creates an error in my already existing JSP page.
<%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %>
--------------- example ----------------------
<%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c"
%> // Creates an error
<html>
<head>
<title> <c:out> Tag Example</title>
</head>
<body>
<c:out value = "${'<tag> , &'}"/>
</body>
</html>
---------------- End ------------------
The error reads:
HTTP Status 500 – Internal Server Error
Type Exception Report
Message:
java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator
Description:
The server encountered an unexpected condition that prevented it from fulfilling the request.
Using Netbeans 22, in my Debian machine I have added the 'JSTL 1.2.7 - jstl-impl' and the 'JSTL 1.2.7 - jstl-api' jar files in the 'Library' subdirectory, but to no avail.
What am I doing wrong?
