You have modeled a SOA composite with a single BPEL process component. Both of the invoke activities in the BPEL process use the same XA connection factory: eis/DB/SOADemo. The InsertData partnerlink inserts a new record in the DEPT table in the database. The storeproc_validate partner link calls a stored procedure that validates this newly inserted record.
Which statement is true about the composite?
A. Invoke1 is capable of detecting omitted XML elements in the input payload and throwing a bindingFault to the caller
B. If invoke1 encounters a primary key constraint violation on insert, the invocation retires a total of 4 times with a starting interval of 1 and a back-off factor of 2.
C. Invoke1 and invoke2 use the same underlying JDBC connection to the database.
D. If invoke2 interaction fils, the insert from Invoke1 is also rolled back.
