acho que é poqrue na sua action vc não associou o seu form tente isso:

<action name="LoginForm" path="/efetuaLogin" type="br.com.caelum.struts.action.LoginAction">   
            <forward name="erro" path="/erro.jsp"/>   
            <forward name="ok" path="/ok.jsp"/>   
        </action>

isso deve resolver
