solved: java.lang.ClassNotFoundException for listener class
I was wong, the deployed context under eclipse and under tomcat autonomous instance were not identical at all. Form some reason when eclipse deploys the web application copy the class files under WEB-INF/services/ under WEB-INF/classes, so the tomcat class loading finds classes were expected -- Hello all. I have developed a web application using Eclipse as an IDE and test environment and it runs as expected. Then I have built a war file and deployed it under another Tomcat instance. In both case tomcat version is 8.5 Under this last instance the application can't start and in the log files I find: 07-Sep-2023 07:48:18.173 SEVERE [http-nio-8080-exec-129] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class [it.archimede.met.obliterazione.zse.servlet.CreaConnessione] java.lang.ClassNotFoundException: it.archimede.met.obliterazione.zse.servlet.CreaConnessione at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1358) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1180) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:545) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:526) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:150) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4613) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5155) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:183) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:743) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:719) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:705) at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:614) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:486) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1634) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:607) at org.apache.tomcat.util.modeler.BaseModelMBean.invoke(BaseModelMBean.java:286) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:819) at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:801) at org.apache.catalina.manager.ManagerServlet.check(ManagerServlet.java:1562) at org.apache.catalina.manager.ManagerServlet.deploy(ManagerServlet.java:990) at org.apache.catalina.manager.HTMLManagerServlet.deployInternal(HTMLManagerServlet.java:320) at org.apache.catalina.manager.HTMLManagerServlet.doPost(HTMLManagerServlet.java:209) at javax.servlet.http.HttpServlet.service(HttpServlet.java:652) at javax.servlet.http.HttpServlet.service(HttpServlet.java:733) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:231) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.filters.CsrfPreventionFilter.doFilter(CsrfPreventionFilter.java:211) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.filters.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:109) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:199) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:96) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:668) at org.apache.catalina.valves.RequestFilterValve.process(RequestFilterValve.java:348) at org.apache.catalina.valves.RemoteAddrValve.invoke
