When we try to use the HiLoKeyGenerator the following exception occurs:
java.lang.IllegalArgumentException: no such field

at net.caixagaliciamoviles.plataforma.sms.mensaje.SMSIdGenerator.getSMSId(SMSIdGenerator.java:27)

The calling code is :
public static String getSMSId() {
log.info ("Generando SMSID");
try

{ InitialContext ctx = new InitialContext(); KeyGeneratorFactory kgf = (KeyGeneratorFactory) ctx.lookup("HiLoKeyGeneratorFactory"); KeyGenerator kg = kgf.getKeyGenerator (); Long id = (Long) kg.generateKey (); String txtId = String.valueOf (id); log.info ("El SMSID generado es [" + txtId + "]"); return txtId; }

catch (Exception e)

{ log.warn ("Error generando SMSID",e); }

log.info ("El ID es BLANCO");
return "";

}

The exception is thrown at " KeyGeneratorFactory kgf = (KeyGeneratorFactory) ctx.lookup("HiLoKeyGeneratorFactory");

If we change to use de UUID generator no exception is thrown in lookup.
