And could you tell me how can I register the listener, if the web-app element of web.xml, hardwired in xerces distributed with Catalina, doesn't support element listener? I've tried to set the appropriate dtd (PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"), I've downloaded the dtd from Sun's site, xmlnorm or emacs's PSGML verified the xml document with element listener, I've added the listener element to the document's header and I've received: tapik@pc4:/opt/jakarta-tomcat-4.0.1> cat logs/catalina.out Starting service Tomcat-Standalone Apache Tomcat/4.0.1 PARSE error at line 578 column 11 org.xml.sax.SAXParseException: The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*)". Starting service Tomcat-Apache Apache Tomcat/4.0.1 tapik@pc4:/opt/jakarta-tomcat-4.0.1> Could you help me? As written in Javadoc for HttpSessionListener, " Implementations of this interface may are notified of changes to the list of active sessions in a web application. To recieve notification events, the implementation class must be configured in the deployment descriptor for the web application.
