Erro em Update/Delete no Hibernate c/ Struts! [MySQL]

Opa galera, seguinte, consigo listar e inserir beleza, mas quando vou atualiza, ele faz é inserir, e no delete dá erro. O que estou errando? O banco é MySQL!

Codigo do update e do delete.

public void update(Object bean) throws Exception  {		
		Transaction tx = session.beginTransaction();
		session.evict(bean);
		session.merge(bean);		
		tx.commit();		
		session.evict(bean);
	}


	public void delete(long id, Class classe) throws Exception  {
		Transaction tx = session.beginTransaction();
		Object obj = session.get(classe, new Long(id));		
		session.delete(obj);
		tx.commit();
		session.evict(obj);
	}


// Chamo assim

public ActionForward update(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {

		UsuarioForm userForm = (UsuarioForm)form;
		Usuario userBean = new Usuario();
		BeanUtils.copyProperties(userBean, userForm);
		userBean.verificaFlags();
		
		UsuarioBusiness userBusiness = UsuarioBusiness.getInstance();
		userBusiness.update(userBean);
		
		search(mapping, form, request, response);
		return mapping.findForward("main");
	}


// e 
	public ActionForward delete(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {

		UsuarioForm userForm = (UsuarioForm)form;
		Usuario userBean = new Usuario();
		try {
			UsuarioBusiness userBusiness = UsuarioBusiness.getInstance();
			userBean = userBusiness.getUserByLogin(userForm.getLogin());
			userBusiness.delete(userBean.getIdUsuario());
		} catch (Exception e) {
			System.out.println("erro: " + e.getMessage());
		}
		search(mapping, form, request, response);
		return mapping.findForward("main");
	}
