In Eclipse IDE right click on project choose properties, choose Deployment Assembly make sure source and deploy path right, also any libs that you use out side web/inf must be deploy in WEB-INF/lib. After that try clean project and clean tomcat server and publish web application again. Check this post hope it can help you eclipse web application and maven dependency issues
