These are the "tag library descriptor" files that describe the custom tags in the various Struts tag libraries. The tld file for any Struts taglibs that you use should be copied into the WEB-INF directory of your web application. (Applications under Servlet 2.3 containers can omit this step if the standard uri is referenced.) That can be achieved as follows. <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %> For Servlet 2.3/2.4 containers only: The Servlet 2.3 and 2.4 specifications simplify the deployment and configuration of tag libraries. The instructions above will work on older containers as well as 2.3 and 2.4 containers (Struts only requires a servlet 2.2 container); however, if you're using a 2.3/2.4 container such as Tomcat 4.x/5.x, you can take advantage of a simplified deployment. All that's required to install the Struts tag libraries is to copy struts.jar into your /WEB-INF/lib directory and reference the ta

Some times we may get ClassNotFoundException- Dispatcher Servlet in Spring MVC , even though we keep the spring.jar and spring-webmvc.jar using configuring the build path. The root cause of this error is your IDE expects the jars to be located physically in the lib folder. So Copy all the required jars in the lib folder, that should solve the problem.
