Can you please answer my query about ODE engine,

I'm looking for it but didn't find anything about it .
As far as I know, the answer is no. It's never been discussed on the
mailing lists and there's no explicit support in the code.
I can affirm Alex's answer of "no", although it's not impossible.
The most difficult part of integrating WSRF resources into a BPEL
process is dealing with the security and delegation requirements that
WSRF resources have (in the general case), and that's work that needs to
be done in the protocol layer (i.e., in AXIS2 or in ServiceMix) as
opposed to in ODE. AFAIK, the only release-worthy work that was done in
this area was done to get an AXIS1 layer (that's part of some other BPEL
engine whose name I've forgotten) working with WS-GRAM for the CaBIG
project.
I'm not the grid expert, but isn't there a difference between (simply)
using WSRF and Grid Services? While the latter of course imply targeting
Grid Security and other stuff, the former are IMO almost conventional
web services whose resources can be addressed by naming resource EPRs
with WS-Addressing headers.
As ODE supports modifying SOAP headers, it should be in principle
possible to add a resource EPR and that way to call/access WSRF
resources with ODE, shouldn't it?
