webservice call inside oracle trigger

Question

Need help in addressing one of the requirement. Requirement is to call salesforce boomi api as an webservice from oracle trigger and I did implement it, but the problem here is, when the trigger gets fired, salesforce boomi reads oracle data thru oracle view and that view is not fetching any rows, but on oracle it fetches the rows, since there is no data returned from the oracle view on salesforce boomi, it is not writing any thing to saleforce, any recommendation.

Thanks, Ramprasad.
