I am building a example web app in
tomcat as part of my study. I have tried to use the listener tag in the web.xml file but tomcat throws an expection when it tries to digest the web.xml as it can't parse the listener tag. The exception lists the the dtd entry for the web-app tag and the listener tag is not is even in it.
Could this be caused by an old version of Tomcat or an old version of servlet.jar?
