OIM API Provision user with custom approval workflow

Hi,

I have write a custom java code using OIM API for provision user. I have also developed and deployed custom multi level approvals workflows. When I am provisioning user from OIM GUI its invoking that custom approval workflow but when executing java code (OIM API) to provision a user its always bypass approval process.

I also have written custom java code to create request for assign role and provision user, when I checking the request id in request tracking.. the request created but with default approval workflow. I want to invoke my custom approval workflow.

Please help me or provide man java code to invoke custom approval on user operations with custom OIM APIs.
