Informix - problemas para conectarme informix

Hola!! Estoy trabajando en una aplicacion desarrollada en Java que utiliza la base de datos de Informix. El gestor de la base de datos esta correctamente configurado ya que puedo acceder sin problema desde el cliente sqleditor pej.

Pero no consigo conectarme desde la aplicacion.
Trabajo en Vista y utilizo como entorno de desarrollo eclipse.
Yo creo que los ficheros de configuracion los tengo correctamente. El error que me saca es el siguiente:
*** Using 'ConfigurationParameters.properties' file for configuration ***
**** CREANDO EL DATASOURCE!!!!!
imedir.util.exceptions.InternalErrorException: com.informix.asf.IfxASFException: Attempt to connect to database server (ol_lola1) failed.
