Chapter 5. Accessing a CMIS Server with a Java Client

Up until now, we have accessed the CMIS server via the low-level AtomPub protocol binding and the Browser protocol binding. This has required a lot of coding, which could be error prone. However, it is always good to know how low-level APIs work before going on to higher-level abstraction APIs. In this chapter, we will look at how the Apache Chemistry project (http://chemistry.apache.org/) offers a high-level API for CMIS.

In this chapter, we will see how we can perform the following tasks from a CMIS Java client:

• Authenticating and connecting to the server

• Fetching repository information including the repository ID and top folder URL

• Listing the content of a folder

• Listing the content types that are available

• Creating, updating, and deleting folders and files

• Downloading the content

• Content versioning

• Managing permissions

• Relationship management

• Searching

Apache Chemistry contains a number of libraries that abstract the CMIS low-level protocol...
