Websphere

Hi,

is there anybody that has successfully been able to configure postgresql 
with a ConnectionPoolDataSource under ibm websphere?
What I really need is an opinion about it because I've been searching so 
much and it seems that neither on the websphere side, nor on the 
postgres one there is something helpful.
The only useful post I've found is this one:

Thank you
