JCO pooling mechanism on EP 5.0 SP5

Hello all,

all examples and documentation about JCO on EP 5.0 SP5 for connecting EP to R/3 talk about using of "pooling mechanism" with classes IJCOClientService and IJCOClientPoolEntry, but these classes use Portal logon information for login/connection to R/3 system and R/3 system have to be defined in files systems.xml and jcodestinations.xml.

Is it possible to use classes IJCOClientService and IJCOClientPoolEntry for connecting to R/3 system with a specific R/3 logon user? Or have we to use "standard" class JCO.PoolManager?

many thanks in advance for every hint and suggestion.

regards
