The tutorial was obviously written before Struts 1.3.8. These TLD files are required for versions 1.2.9 and below, but for version 1.3.8, they are bundled in the struts-taglib-1.3.8.jar file and should not be copied to the WEB-INF folder.
Your tutorial will also no doubt tell you to use taglib declarations in your JSP that are incorrect for version 1.3.8. Here are the correct ones. <blockquote>code:<pre name="code" class="core"><%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %> <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %> <%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %></pre></blockquote>
