hi, in my servlet i called an instance of a class.java( a class that construct an html table) in order to create this table in my jsp.

the servlet is like the following:

String report=request.getParameter("selrep");
String datev=request.getParameter("datepicker");
String op=request.getParameter("operator");
String batch =request.getParameter("selbatch");

System.out.println("report kind was:"+report);
System.out.println("date was:"+datev);
System.out.println("operator:"+op);
System.out.println("batch:"+batch);


if(report.equalsIgnoreCase("Report Denied"))
{
    DeniedReportDisplay rd = new DeniedReportDisplay(); 
    rd.ConstruireReport();
}
else if(report.equalsIgnoreCase("Report Locked"))
{
    LockedReportDisplay rl = new LockedReportDisplay(); 
    rl.ConstruireReport();
}

request.getRequestDispatcher("EspaceValidation.jsp").forward(request, response);

in my jsp i can not display this table even empty or full.

note: exemple a class that construct denied Report has this structure:

   /*constructeur*/
                  public DeniedReportDisplay() {}

 /*Methodes*/

                 public StringBuffer ConstruireReport()

                 { 
                     StringBuffer retour=new StringBuffer();
                     int i = 0;
                     retour.append("<table border = 1 width=900 id=sheet  align=left>");    
                     retour.append("<tr bgcolor=#0099FF>" );
                     retour.append("<label> Denied Report</label>");
                     retour.append("</tr>");                       
                     retour.append("<tr>"); 

 String[] nomCols ={"Nom","Prenom","trackingDate","activity","projectcode","WAName","taskCode","timeSpent","PercentTaskComplete","Comment"};
 //String HQL_QUERY = null;                      
  for(i=0;i< nomCols.length;i++)
  {
    retour.append(("<td bgcolor=#0066CC>")+ nomCols[i] + "</td>");

   }
  retour.append("</tr>");

     retour.append("<tr>");

                 try {

      }   
 //terminer la table.
                          retour.append ("</table>");

                          tx.commit();


                } catch (HibernateException e) 
                 {

              e.printStackTrace();
                 }

                 return retour;
 }

thanks for help.
