Hello, I've run into the issue where tomcat (5.5.15) is not able to undeploy my webapp after I incorporated struts2 into my web app. The undeploy deletes all files but the struts2-core-2.0.8.jar in <CATALINA_HOME>/webapps/myapp/WEB-INF/lib. I am wondering if there is some reference to this struts jar that tomcat is not able to delete it. As far as configuration goes, I simply followed everything said in the Struts2 Bootstrap tutorial - copied JARs and struts.xml to right place and edited my app's web.xml to include the FilterDispatched for struts2. All references to struts is contained inside my webapp and there is nothing at the tomcat level. Any insights into this would be helpful. I thought I would check to make sure I am fine on the struts side before posting to the tomcat forum. Undeploy fails with the exception: INFO: Reloading context [/GlobalXMS] Jun 28, 2007 11:39:14 AM org.apache.catalina.core.StandardContext stop INFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/ GlobalXMS] has not been started Jun 28, 2007 11:39:14 AM org.apache.catalina.startup.ContextConfig applicationWe bConfig INFO: Missing application web.xml, using defaults only StandardEngine[Catalina].
