Hata: Ortam veya sistem özelliğinde sınıf adı belirtmeniz gerekiyor

Question

Java EE uygulamalarının geliştirilmesinde yeniyim ve bu konuda gerçekten kafam karıştı. Çok fazla cevap buldum ama sorunumu çözemiyorum.

Bu

hatadır:

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

Ve bu benim kodudur:

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()); 
    } 

Ve bu dosya benim JNDI.properties geçerli:

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
