I am trying to learn to work with Convention plugin 188.8.131.52 I read through http://cwiki.apache.org/WW/convention-plugin.html to set up the hello-world example. But i get 404 error with the url. All i did to setup the plugin was to put the convention plugin jar in my webapp's web-inf/lib. I dont know why then the plugin is not working?
You have provided almost no information with which to help.
Have you set devMode to true and enabled DEBUG logging for struts, xwork, and the convention plugin? Are there any errors on startup? Have you changed any of the default plugin settings? What's your class hierarchy? Have you used any annotations? Are your result pages in place? Have you followed the troubleshooting guide on the page you linked to?
