Pentaho connection to Oracle CRM On Demand

Good morning to everybody!

I'm trying to extract data from Oracle CRM On Demand, but with no luck.

I think I should use the HTTP Post component, but I'm not sure.

The only thing I know is that Oracle CRMoD can be queried using WebServices.

Does anybody managed to connect to it ?

Thanks in advance, any help would be appreciated.

Best regards

Alessio
