You can connect to specific Couchbase buckets (in place of using the default bucket, or a hostname/port combination configured on the Couchbase cluster) by using the Couchbase URI for one or more Couchbase nodes, and specifying the bucket name and password (if required) when creating the new CouchbaseClient object.

For example, to connect to the local host and the default bucket:

List<URI> uris = new LinkedList<URI>();

    uris.add(URI.create("http://127.0.0.1:8091/pools"));
    try {
      client = new CouchbaseClient(uris, "default", "");
    } catch (Exception e) {
      System.err.println("Error connecting to Couchbase: " + e.getMessage());
      System.exit(0);
    }

The format of this constructor is:

CouchbaseClient(URIs,BUCKETNAME,BUCKETPASSWORD)

Where:

The returned CouchbaseClient object can be used as with any other CouchbaseClient object.
