After I depolyed the .ear to the engine then in the web dynpro content administrator I try to create the Jco connections for WD_FLIGHTLIST_MODELDATA_DEST and WD_FLIGHTLIST_RFC_METADATA_DEST respectively. But I meet the following erroes:

1.for WD_FLIGHTLIST_MODELDATA_DEST

here I have some issues:

1. client 000 is right or not? it should be login client of backend R/3, right?

the backend R/3 login client is 100, should I change 000 to 100?

2.Used mathod: User/Password

is the backend R/3 login or J2ee engine login?

thanks a lot!!
