As per the docs[1], this only works for a previously-deployed application. Deploying a new application requires additional parameters. > This is the way we have done it for years on Tomcat 6.

Thanks.

You've been using /my-app above, but probably in an attempt to anonymize your application. Always helps to double-check the speling. > 16:49:24.847 SEVERE [http-nio-8080-exec-1] > org.apache.catalina.core.ApplicationContext.log Manager: > ManagerServlet.undeploy[/das-qa-java8] > javax.management.InstanceNotFoundException: > Catalina:type=Deployer,host=localhost at > com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getMBean(DefaultMBeanServerInterceptor.java:1095) > at > com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:816) > at > com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:801) > at > org.apache.catalina.manager.ManagerServlet.removeServiced(ManagerServlet.java:1530) > at > org.apache.catalina.manager.ManagerServlet.undeploy(ManagerServlet.java:1440) Seems like it can't find the application. Can you start Tomcat, deploy the application, and then connect to the server using JMX? You should be able to find the application under /Catalina/Deployed/localhost, then choose "Operations" and execute the "isDeployed" operation with the argument "/my-app". It should return "true". If it doesn't something isn't quite right with your setup. For example, are you using the <Host name="localhost"> for this application? The Manager expects that it (the Manager) and your application are running under the same <Host>. Hmm... that stack trace shows that the application should have been stopped + deleted by the time this removeServiced() method is called. What do the log files say? I'm guessing something else is going wrong, such as the inability for Tomcat to remove the application artifacts from the disk. Maybe a permissions problem? The initial error is probably being masked by the exception thrown during removeServiced() (which is called in a finally{} block). -chris [1] https://tomcat.apache.org/tomcat-8.5-doc/manager-howto.html#Deploy_a_previously_deployed_webapp --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
