Ejb ref resolution error

Question

Dear all,
I try to set up a simple ejb environment. I managed to run the converter example from the JEE tutorial bundle in the NetBeans / Glassfish environment.
Then I tried to write a standalone java client. The code consists in essential of the statements
Context ctx = new InitialContext();
ctx.lookup("converter.ejb.Converter");Unfortunately, running this program from a windows command line by the "java" command (plus some classpath settings) results in:
NamingException: ejb ref resolution error for remote business interface converter.ejb.ConverterThe jndi entries of the app server are
jndi root
  |
  |--  converter.ejb.Converter#converter.ejb.Converter
  |--  converter.ejb.Converter__3_x_Internal_RemoteBusinessHome__
  |
  |--ejb
      |-- converter.ejb.Converter All environment settings are the standard ones.
Has anybody an idea, what the problem could be ? Thank you very much for your help.
Ralph

Hi,
thanks for your interest. The client code is
// file ConverterClient
package ejb.clients;
import javax.naming.*;
import java.util.*;
public class ConverterClient
  public static void main(String[] args)
    try
      Context ctx = new InitialContext();
      ctx.lookup("converter.ejb.Converter");
      Enumeration e = ctx.list("");
      while (e.hasMoreElements())
        System.out.println(e.nextElement());
    catch(NamingException ex)
      ex.printStackTrace();
}The interface:
// file Converter
package converter.ejb;
import java.math.BigDecimal;
import javax.ejb.Remote;
@Remote
public interface Converter {
    public BigDecimal dollarToYen(BigDecimal dollars);
    public BigDecimal yenToEuro(BigDecimal yen);
}The bean code is
// file ConverterBean
package converter.ejb;
import java.math.BigDecimal;
import javax.ejb.Stateless;
@Stateless
public class ConverterBean implements converter.ejb.Converter {
    private BigDecimal euroRate = new BigDecimal("0.0070");
    private BigDecimal yenRate = new BigDecimal("112.58");
    public BigDecimal dollarToYen(BigDecimal dollars) {
        BigDecimal result = dollars.multiply(yenRate);
        return result.setScale(2, BigDecimal.ROUND_UP);
    public BigDecimal yenToEuro(BigDecimal yen) {
        BigDecimal result = yen.multiply(euroRate);
        return result.setScale(2, BigDecimal.ROUND_UP);
}It's been deployed successfully with NetBeans on Glassfish app server.
The commands for compiling and running the client. "c:\java\JEE" is the installation dir for jee.
c:\java\programs\src javac -d ..  -cp c:\java\JEE\lib\javaee.jar;c:\java\JEE\lib\appserv-rt.jar   ConverterClient.java
c:\java\programs java -cp c:\java\JEE\lib\javaee.jar;c:\java\JEE\lib\appserv-rt.jar;.  ejb.clients.ConverterClient
