If we are going to plug Java connectors for CouchDB I might aswell
mention Ektorp.
In contrast to its peers, It has good refence documentation:
http://www.ektorp.org/reference_documentation.html
It is quite flexible in terms of mappable types, you can use plain
Objects, Maps or JsonNodes (DOM like API)
Here's the project site:
http://code.google.com/p/ektorp/

Hi,

By the way, we have created yet another java client library.
We use it for information visualisation (which means displaying a lot of data at the same time). Therefore, the emphasis is put on improving read performance (cached bulk GET). On _changes, the cache is cleared and the observers are notified.
It's called RESTDatabase:
http://porphyry.git.sourceforge.net/git/gitweb.cgi?p=porphyry/porphyry;a=blob_plain;f=src/org/hypertopic/RESTDatabase.java;h=b7d67a3146475d9057dd8fec40967dd10514146d;hb=HEAD
And it is tested here:
http://porphyry.git.sourceforge.net/git/gitweb.cgi?p=porphyry/porphyry;a=blob_plain;f=src/org/hypertopic/RESTDatabaseTest.java;h=6b5dfcb2d1022fe586b2c22b77ee517aa4a20b54;hb=HEAD
We minimized the dependencies to a single modified org.json library:
http://porphyry.git.sourceforge.net/git/gitweb.cgi?p=porphyry/porphyry;a=tree;f=src/org/json;h=311adf0af9d49f0dfc1d9fbafeb113bb23eb29fe;hb=HEAD

I recommend using a CouchDB library for Java. I use jcouchdb [0] myself and you should be able to use that to query a view and iterate over the ViewResult to add items to a Vaadin Table.
