It's my first time to touch Struts. Here refers to Struts 2.1.8.1. The Hello World is deployed under Tomcat 6.0.20.
The error is caused by a typo error of the struts tag url , should be <%@ taglib prefix="s" uri="/struts-tags " %> .
<%@ taglib prefix="s" uri="/strutss-tags" %>
<html>
<head>
<title> Hello World!</title>
</head>
<body>
<h2><s:property value="message"/> </h2>
</body>
</html>
the error is reported as below using invalid code above which I mis-typed /strutss-tags:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
