How does a D2 client application retrieve content/files from a Documentum repository?

Mikael Thorell · May 12, 2023

We are trying to intercept when a content/file for a specific type of object is retrieved from the Documentum repository for all our DFC-based client aplications by overriding the getFileEx and getContentEx methods in a TBO distributed to all client applications.

We have confirmed that the D2 client is honoring the TBO by getting traces of usage of other methods in the TBO. This makes me draw the conclusion that D2 is using a non-traditional way to retrieve content/files for documents from a Documentum repository.

If D2 is not using the getFile or the getContent methods, how does a D2 client application retrieve content/files from a Documentum repository then?

It depends on your setup but most web clients nowadays will probably use ACS, not getfile. D2 normally relies on the D2ContentService which will perform the necessary checks to determine the best way to get the content. You can override this by implementing a D2FS Listener Plugin. There is such an example in the D2 SDK.

Thanks for the advice. I will look into the D2 SDK and create a listener plugin.

If using D2. D2 itself can use thin, java and wsctf mode. Look at the documentation related to it. There are configs in settings.properties. There is more info too in the Support website. A Technical Paper (Technical Paper - OpenText™ Documentum™ D2 Web Socket Content Transfer Framework (WSCTF)): https://support.opentext.com/csm?sys_kb_id=68420f1f4786295029776377536d43ca&id=kb_article_view&sysparm_rank=4&sysparm_tsqueryId=c5d300b697f2e9908a227ccfe153af9c
