How do I get jar files to work? Learning Tomcat I have a simple "HelloServlet" class. When compiled and the class file is inserted into the directory
/opt/tomcat/webapps/test/WEB-INF/classes/example and the web.xml file given below is placed in /opt/tomcat/webapps/test/WEB-INF/ and tomcat is restarted then the url http://localhost:8080/test/hello page reads: Hello, world! But if the same class is placed in a jar file and this jar file is inserted into any of the following directories and given permissions tomcat:tomcat /opt/tomcat/webapps/test/WEB-INF/lib /opt/tomcat/common/lib /opt/tomcat/shared/lib when tomcat is restarted and the same url is addressed first there is < Blank page > the second time the page is refreshed there is Status 500: javax.servlet.ServletException: Wrapper cannot find servlet class example.HelloServlet or a class it depends on and the third and all subsequent times the page is refreshed there is Status 400: Servlet hello is not available How do I get jar files to work?
