calling a java class in a servlet
- by kawtousse
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*/
@SuppressWarnings("unchecked")
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 {
s= HibernateUtil.currentSession();
tx=s.beginTransaction();
Query query = s.createQuery("select opcemployees.Nom,opcemployees.Prenom,dailytimesheet.TrackingDate,dailytimesheet.Activity," +
"dailytimesheet.ProjectCode,dailytimesheet.WAName,dailytimesheet.TaskCode," +
"dailytimesheet.TimeSpent,dailytimesheet.PercentTaskComplete from Opcemployees opcemployees,Dailytimesheet dailytimesheet " +
"where opcemployees.Matricule=dailytimesheet.Matricule and dailytimesheet.Etat=3 " +
"group by opcemployees.Nom,opcemployees.Prenom" );
for(Iterator it=query.iterate();it.hasNext();)
{
if(it.hasNext()){
Object[] row = (Object[]) it.next();
retour.append("<td>" +row [0]+ "</td>");//Nom
retour.append("<td>" + row [1] + "</td>");//Prenom
retour.append("<td>" + row [2] + "</td>");//trackingdate
retour.append("<td>" + row [3]+ "</td>");//activity
retour.append("<td>" + row [4] +"</td>");//projectcode
retour.append("<td>" + row [5]+ "</td>");//waname
retour.append("<td>" + row [6] + "</td>");//taskcode
retour.append("<td>" + row [7] + "</td>");//timespent
retour.append("<td>" + row [8] + "</td>");//perecnttaskcomplete
retour.append("<td><input type=text /></td>");//case de commentaire
}
retour.append("</tr>");
}
//terminer la table.
retour.append ("</table>");
tx.commit();
} catch (HibernateException e)
{
retour.append ("</table><H1>ERREUR:</H1>" +e.getMessage());
e.printStackTrace();
}
return retour;
}
thanks for help.
