Hello Sir/Madam I am using Tomcat 4.1
I have created a web application having context as "gm". All classes are placed at appropriate places, and jsps are at approprate places. In this application we are using struts frame work. I copied a) struts.jar b) commons-beanutils.jar c) commons-collections.jar d) commons-digester.jar e) commons-validator.jar in my web application's "WEB-INF/lib" And placed *.tld files related to struts in my application's "WEB-INF" folder. placed web.xml and struts-config.xml in "WEB-INF" folder. and when i run the application and click the Login.jsp i get following exception description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Cannot inherit from final class at
