Error : Need to specify class name in environment or system property

Question

I'm new in development of Java EE applications and I'm really confused about this. I've found so many answers but I can't resolve my problem.

This is the error:

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

And this is my code :

public class Test {

    public static void main(String[] args) {
        List<Auto_2G> auto2 = new ArrayList<Auto_2G>();
        GestionCellRef2GRemote t = null;
        Context contxt=null ;
        //GestionCellRefDualmodeRemote p = null;
        //Auto_Dualmode autodualmode = new Auto_Dualmode();
        FileInputStream file=null;
        HSSFWorkbook classeur=null ;
        HSSFSheet feuille=null;
        Row roww=null;

        try {
            try {
                contxt = new InitialContext();
            } catch(NamingException e) {

            }
            t = (GestionCellRef2GRemote) contxt.lookup("/webpfe/GestionCellRef2G!tn.orange.pfe.services.GestionCellRef2GR emote");
            file= new FileInputStream(new File("test.xls"));
            classeur = new HSSFWorkbook(file);
            feuille = classeur.getSheetAt(0);
            int i=1;

            while(roww!=null) {
                roww=feuille.getRow(i);

                for (Auto_2G auto2g:auto2) {
                    auto2g.setBSC_Name(roww.getCell(0).getStringCellValue());
                    auto2g.setBTS_NAME(roww.getCell(2).getStringCellValue());
                    auto2g.setCELL_NAME(roww.getCell(4).getStringCellValue());

                    t.ajout2G(auto2g);
                }
                i++;
            }
            file.close();
        } catch (Exception e) {
            System.out.println("erreur"+e);
        }

        for(Auto_2G auto2g:auto2){
        System.out.println(auto2g.getId());
    }

And this is my JNDI.properties file:

java.naming.factory.url.pkgs=org.jboss.ejb.client.naming
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url=http-remoting://localhost:8181
jboss.naming.client.ejb.context=true
jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT=false

This is the code after the update :

  public class Test {

        List<Auto_2G> auto2 = new ArrayList<Auto_2G>();
        GestionCellRef2GRemote t = null;
        Context contxt=null ;
        //GestionCellRefDualmodeRemote p = null;
        //Auto_Dualmode autodualmode = new Auto_Dualmode();
        FileInputStream file=null;
        HSSFWorkbook classeur=null ;
        HSSFSheet feuille=null;
        Row roww=null;
        Properties prop = new Properties(); 
        prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        prop.put(Context.PROVIDER_URL, "http-remoting://localhost:8181");
         prop.put("jboss.naming.client.ejb.context", true);
         prop.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
try {

    try{
        contxt = new InitialContext(prop);
    }
    catch (NamingException e)
    {e.printStackTrace();}      

    t = (GestionCellRef2GRemote) contxt.lookup("/GestionCellRef2G!tn.orange.pfe.services.GestionCellRef2GRemote");
    file= new FileInputStream(new File("test.xls"));
    classeur = new HSSFWorkbook(file);
 feuille = classeur.getSheetAt(0);
 int i=1;

 while(roww!=null){
         roww=feuille.getRow(i);
         for(Auto_2G auto2g:auto2){

    auto2g.setNumber_of_2G_Neighbor_Cell_for_GSM_Cell(Integer.parseInt(roww.getCell(28).getStringCellValue()));
    auto2g.setNumber_of_3G_Neighbor_Cell_for_GSM_Cell(Integer.parseInt(roww.getCell(29).getStringCellValue()));

    t.ajout2G(auto2g);
         }

    i++;

    }


    file.close();

} catch (Exception e) {
System.out.println("erreur"+e);
e.printStackTrace();
}


for(Auto_2G auto2g:auto2){
    System.out.println(auto2g.getId());
}

            // Créer un objet classuer



            // Lire la première feuille de ce classuer


            // Créer un Itérateur sur la feuille
            //Iterator<Row> rowIterator = feuille.iterator();



        // insertion en BD

        // p.ajoutDm(autodualmode);

    }
