Integration

Hi,
I have a question related to the Inter Process Communication.
It is the first time I try to configure this and probably you can help me.
I have an environment with WLS with two engines and I want that from the processes of one engine create instances in the process of the other engine. I have created two small sample projects to test how it works.
I have started with the easiest scenario. I have deployed two engines to the WL Admin Server. I have only one organization. I have deployed each project to each engine. And now I have to configure in the external processes in the process administrator. The first thing to configure is the Organization, that I suppose is the organization that appears when you log to the process administrator, in my case it is oracle, is this how to be configured or shall I put the FDI name or the UO that appears at the process level?
After configuring the organization I have to set up some properties:
1.- Organizational Unit: I have no Organizational Units defined so can I leave this blank or shall I put "/".
2.- Process: I have put here the process that I want to instantiate that belongs to the project deployed in the other engine.
3.- URL: t3://192.168.1.33:7001 where my adminserver is.
4.- User: Whch user I have to put here?, the admin user?
When I launch the process I have an exception, sorry it is in spanish, but basically says that the process that I want to instantiate can not be found in the directory service oracle.
ENGL_01215 Se ha producido una excepción mientras se ejecutaba una transacción. Detalles: La instancia '/Subvencion#Default-1.0/8/0@oracle' de la actividad '/Subvencion#Default-1.0/ProcessCreation[Tramitar]' no ha podido crear una instancia en el proceso '/Tramitar@oracle'. Debido a: No se ha encontrado el proceso 'Tramitar' en el servicio de directorios: 'oracle' Detalle:Compruebe que el servicio de directorio funciona correctamente y que el proceso se ha logrado implantar. Tenga en cuenta que los Engines J2EE de Oracle necesitan una configuración de referencia para comunicarse. fuego.papi.exception.CannotCreateInstanceException: La instancia '/Subvencion#Default-1.0/8/0@oracle' de la actividad '/Subvencion#Default-1.0/ProcessCreation[Tramitar]' no ha podido crear una instancia en el proceso '/Tramitar@oracle'

So basically I have something of the above parameters that is not OK, but I have made different combinations in that configuration and always I have the same exception.
Can anybody help me?
Thank you very much
Kind regards
