finding the underlying datasource

Hi,

We have installed the SAP Netweaver2004s environemant with

a)Web AS Java

b)Web AS Java + ABAP

Is there anu API or UME API or any programmatic approch form where we can know if the underlying datasource is of what type.

I require this as based on the server configuration my code flow will change.

How this can be done.

Best Regards

Manoj
