Because something at a higher level in the classloader hierarchy is hanging on to a reference to your webapp's classes (or classloader). As Mark noted, loggers are infamous for this behavior, as is improper use of ThreadLocal. > Isn't Tomcat responsible for unloading my classes > when I order it to undeploy my webapp?. Tomcat does clean up what it knows about, but it can't really protect against ill-mannered code in your webapp or libraries. Here's a link from the Tomcat FAQ that discusses the issue: http://opensource.atlassian.com/confluence/spring/pages/viewpage.action?pageId=2669 - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
