Premigration considerations: Access framework clients
Do not develop any new clients using the CORBA IDL interface APIs. This is not supported in IBM BPM.
If you develop clients using the CORBA IDL interface APIs, you will not be able to invoke the migrated collaboration. Instead, migrate these clients to a supported protocol, such as WS, HTTP, or JMS.
