This question is better suited to OwnCloud's community forum. Once you find out how they support doing this, come back and we can help you do it with Talend.
I don't know if the ownCloud community could help in this topic. Because my need's is simple : générating files in talend and send it to the folder in owncloud. Actually i do this manually : i generate file and i upload them in the owncloud.
In order for you to do this with Talend, you will need to use an API provided by OwnCloud. Talend will be able to do this, but we will need to know the details of the API that OwnCloud provides. At the moment it is a bit like asking for someone to give you a lift home without giving them the address or even what country you live in. A little more detail of what OwnCloud support will help massively.
