I'm trying to lookup a datasource from a java class that IS NOT AN EJB. (The code is the one of the DAO pattern provided by SUN microsystem).

I'm getting a javax.naming.NameNotFoundException: Missing Node when I'm trying to lookup inside OrderDAOImpl

public class OrderDAOImpl implements OrderDAO {


protected transient Connection dbConnection = null;


private transient DataSource datasource = null;


public OrderDAOImpl() throws OrderDAOSysException {


try {


InitialContext ic = new InitialContext();


datasource = (DataSource) ic.lookup(JNDINames.ESTORE_DATASOURCE);


}


catch (NamingException ne) {


throw new OrderDAOSysException("NamingException while looking" +
" up DataSource Connection " +
JNDINames.ESTORE_DATASOURCE +
":
" + ne.getMessage());


}


}
...


}

I can see the datasource from within an EJB, but how can I do the same thing from the class mentioned above?

Thanks in advance
