Galera olha esse meu JSP, preciso colocar um button para buscar um metodo na minha action como posso fazer isso me sujeriram usar javascript mais nao teria outra maneira?

JSP

        <title><bean:message key="titulo"/></title>
    <html:base/>
    </head>

            <html:submit value="Salvar"/>            
        </html:form>
    </body>
</html:html>

Action

public class ContaAction extends DispatchAction {
    
private final static String SUCCESS = "success";    
           
    public ActionForward salvar(ActionMapping mapping, ActionForm  form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
           
        HttpSession session = request.getSession();
        
        ContaForm contaForm = (ContaForm) form;
        Conta conta = new Conta();
        BeanUtils.copyProperties(conta, contaForm);
        
        PersistenciaDAO persistencia = new PersistenciaDAO();
        
        persistencia.salvar(conta);
        
        return mapping.findForward(SUCCESS);        
                
    }
    
    public ActionForward deletar(ActionMapping mapping, ActionForm  form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
           
        HttpSession session = request.getSession();
        
        ContaForm contaForm = (ContaForm) form;
        Conta conta = new Conta();
        BeanUtils.copyProperties(conta, contaForm);
        
        PersistenciaDAO persistencia = new PersistenciaDAO();
        
        persistencia.deletar(conta);
        
        return mapping.findForward(SUCCESS);        
                
    }
    
}

Susgentão que me deram

   1. funtion funcaoExemplo(){  
   2. document.forms[0].action="suaAction.do";  
   3. document.submit(0);  
   4. }

Mais onde irei passar o methodo deletar nesse javascript, pq ali so mostra como chamar a action
