Hi first of all its a problem not of deployment, its problem when you accessing the page javax.faces.FacesException: An exception occurred processing JSP page /Todo.jsp at line 21
Second you have not added any details about version of you MyFaces libs and you env. Third - check the constructor of class de.vogella.jsf.todo.model.Todo - there must be one without parameters, I suspect that it has only constructors with parameters 2010/10/26 El Arbi ABOUSSOROR
