cannot undeploy and deploy web app in tomcat

Question

When I stop and undeploy the old verstion and tried to deploy a new one using tomcat manager, the message shows ok but the app didn't show up in the application list. Then I delete the war file and directory in both webapps and work directory, and deploy again, it still the case. I google it but cannot find a useful answer. So I can only deploy war file with different name now. Any one can help?

Answer 1

Stop an application before undeployment. It helped me.
