n Here is my code:
SessionEJBBean.java

package lab;

import java.math.BigDecimal;

import javax.ejb.Stateless;

@Stateless(name="SessionEJB")
public class SessionEJBBean implements SessionEJB {
public SessionEJBBean() {
}

public BigDecimal poundToYen(BigDecimal pounds) {
BigDecimal result = pounds.multiply(yenRate);
return result.setScale(2,BigDecimal.ROUND_UP);

}

public BigDecimal poundToEuro(BigDecimal pounds) {
BigDecimal result = pounds.multiply(euroRate);
return result.setScale(2,BigDecimal.ROUND_UP);


}

BigDecimal yenRate = new BigDecimal("211.6");
BigDecimal euroRate = new BigDecimal("1.46");


}


Here is my client code:
SessionEJBBean.java

package lab;

import java.math.BigDecimal;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import oracle.toplink.essentials.mappings.converters.Converter;

public class SessionEJBClient {
public static void main(String [] args) {
try {
final Context context = getInitialContext();
SessionEJB sessionEJB = (SessionEJB)context.lookup("SessionEJB");
// Call any of the Remote methods below to access the EJB
SessionEJBClient converter = (SessionEJBClient)context.lookup("Converter");
BigDecimal param = new BigDecimal("100.00");
// BigDecimal amount = converter.poundToYen(param);
BigDecimal amount = sessionEJB.poundToYen(param);

System.out.println(param+" Pounds is "+amount+" Yen");
amount = sessionEJB.poundToEuro(param);
System.out.println(param+" Pounds is "+amount+" Euros");


} catch (Exception ex) {
ex.printStackTrace();
}
}

private static Context getInitialContext() throws NamingException {
// Get InitialContext for Embedded OC4J
// The embedded server must be running for lookups to succeed.
return new InitialContext();
}
}

Im stuck with this problem could solve the issue??

All comments are highly welcome. please help me out.
