Por exemplo, fiz um teste....

package br.com.surson.negocio;

import java.util.Iterator;

import java.util.LinkedList;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionForward;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.*;

public class ExcluirCursosAction extends Action{

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,

HttpServletResponse response)throws Exception {

ActionErrors errors = new ActionErrors();

try{

HttpSession s = request.getSession();

String idCurso = request.getParameter("idCurso");

// remove o bean da pagina altera jsp para garantir que não haja sugeira

// traz a lista de cursos para poder listá-los afim de achar o que bate com a solicitação

LinkedList listaCursos = (LinkedList)s.getAttribute("listabean");

Iterator i = listaCursos.iterator();

while (i.hasNext()){

Curso curso = (Curso) i.next();

if (curso.getIdCurso()== Integer.parseInt(idCurso)){

AdminCursos c = new AdminCursos();

c.excluirCurso(curso);

LinkedList lista = c.obterListasCursos();

s.setAttribute("listabean", lista);

break;

}

}catch (Exception e) {

return(mapping.findForward("failure"));

}

return(mapping.findForward("success"));

}

package br.com.surson.negocio;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.*;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionMessage;

// função de lidar com os campos do nosso formulário... Ele Validam e resetam

public class SalvarCursoForm extends ActionForm{

private int idCurso;

private String curso;

public void reset(ActionMapping mapping, HttpServletRequest request){

idCurso = 0;

curso = "";

}

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request){

ActionErrors errors = new ActionErrors();

if (( curso == null) || (curso.length()<1)){

errors.add("curso", new ActionMessage("Curso é requerido"));

}

return errors;

}

public void setIdCurso(int idCurso){

this.idCurso = idCurso;

}

public int getIdCurso(){

return this.idCurso;

}

public void setCurso(String curso){

this.curso = curso;

}

public String getCurso(){

return this.curso;

}
