How to set name of uploaded document using EMC/CMIS

Hello,

I have written a sample code to upload the document using EMC/CMIS into the documentum repository. I am making use of 'createDocument' operation of the Object service (SOAP Based approach) to ingest the document. Thought the document is ingested successfully I am not able to set the name of the document. The name of the document after ingestion seems to be generated randomly something like 'dfs333.....tmp' . The api 'setFileName' of the

'CmisContentStreamType' does not seem to be having any effect on setting the name of the ingested document.

How do we set the name of the ingested document so that it actually reflects the correct name ? i.e. For example if I upload a document named 'sample.pdf' I expect the file ingested into the repository to have the same name. How can we achiev this in CMIS?
