I am running spring framework with Tomcat 4.1.31. In order to get the webApplicationContext to work, I have the following lines in my web.xml:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
......
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListe ner
</listener-class>
</listener>
.....
</web-app>
but I got the following error message when Tomcat starts up:

looks like the listener tag is not valid . But when I check the DTD file, listener tag is valid. The strange thing is that even with the exception, my actin class can still use WebApplicationContext to load a bean from applicationContext.xml file. Here is a code segment from my baseAction class:
public void setServlet(ActionServlet actionServlet) {
super.setServlet(actionServlet);
ServletContext servletContext = actionServlet.getServletContext();
WebApplicationContext wac = WebApplicationContextUtils
.getRequiredWebApplicationContext(servletContext);
this.nexus = (NexusFacade) wac.getBean("nexus");
}
Any suggestions, comments, solutions would be highly appreciated.
