The API was build from real usage patterns which were extracted from real use cases. I wanted to ensure that the API is consistent and pleasant to use. - - See [[http://wiki.github.com/isterin/jrelax|JRelax project at github]]. - - === Dependencies === - * Restlet 2.0 (http://www.restlet.org/) - * Jackson (JSON Processor - http://jackson.codehaus.org/) - - = jcouchdb = - jcouchdb is a new java5 CouchDB driver which allows you to choose your favourite style of combining Java and CouchDB. From totally schema-less, collections-based Documents to a graph of your own java objects or something in between. - - See the [[http://code.google.com/p/jcouchdb/|jcouchdb project at google code]] for more details. - - = DroidCouch = - - DroidCouch is a minimal Android library for using CouchDB, licensed under the MIT license. The intention is to make a small Java library well suited for Android mobile development. - - See [[http://github.com/sig/DroidCouch/|DroidCouch at GitHub]] for more details. - - = CouchDB4J = - CouchDB4J is an updated Java library for CouchDB. It handles the REST style calls to the CouchDB server behind the scenes, and give you a handle on the JSON objects directly. CouchDB4J uses JSON-lib to handle mapping to/from JSON objects, which makes getting/setting properties on the objects very easy. You can even map Java objects to JSON objects and back to make the process easier. - - With CouchDB4J, you create a Session object that handles the CouchDB server communication. From here, you can get a handle on your Database. From the ''Database'' you can run views or retrieve ''Documents''. A ''!ViewResult'' is a special type of ''Document'' which contains the id's of the ''Documents'' that matched your view function. - - == Dependencies == - * http://github.com/mbreese/couchdb4j - * [[http://commons.apache.org/|Apache commons]] - * commons-httpclient - * commons-beanutils - * commons-codec - * commons-collections - * commons-lang - * commons-logging - * [[http://json-lib.sf.net/|JSON-lib]] - * json-lib-2.0 - * ezmorph - - == Sample Usage == - {{{ - Session s = new Session("localhost",5984); - Database db = s.getDatabase("foodb"); - - Document doc = db.getDocument("documentid1234"); - doc.put("foo","bar"); - db.saveDocument(doc); - - Document newdoc = new Document(); - newdoc.put("foo","baz"); // same as JSON: { foo: "baz"; } - db.saveDocument(newdoc); // auto-generated id given by the database - - // Running a view - ViewResults result = db.getAllDocuments(); // same as db.view("_all_dbs"); - for (Document d: result.getResults()) { - System.out.println(d.getId()); - - /* - ViewResults may not actually contain the full document, only what the view - returned. So, in order to get the full document, you need to request a - new copy from the database. - */ - - Document full = db.getDocument(d.getId()); - } - - // Ad-Hoc view - ViewResults resultAdHoc = db.adhoc("function (doc) { if (doc.foo=='bar') { return doc; }}"); - }}} - - = LightCouch = - LightCouch aims at providing a simple and easy-to-use APIs for CouchDB. - - It offers a reliable and lightweight persistence interface with minimal setup and code dependency. - - - Visit the website at [[http://www.lightcouch.org/|LightCouch.org]] for a Getting Started guide and check out the [[https://github.com/ahmedyha/LightCouch|source code on Github]]. - - == Older Libraries == - Older CouchDB Java library (doesn't support newer JSON syntax): - - . http://code.google.com/p/couchdb-lib/ -
