access sharepoint documents from J2EE system

I have a J2EE online system and I am integrating office365 and sharepoint online to this system.

My Goal: access documents that are inside the sharepoint document library through my J2EE system.

What I only have now: - My J2EE system - Office 365 account (that includes "Sharepoint Online")

What are the steps n开发者_如何学JAVAeeded in order to reach my goal ? (for example: installing sharepint server, downloading sharepoint administrator toolkit, how to use contect management interoperability services CMIS, is there any sharepoint development needed...etc )

Thanks a lot.
