My first error of Hello Wolrd Struts

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
