A few real-world web applications that use RESTful web services include most blog sites. These are considered RESTful in that most blog sites involve downloading XML files in RSS or Atom format which contain lists of links to other resources. Other web sites and web applications that use REST-like developer interfaces to data include Twitter and Amazon S3 (Simple Storage Service). With Amazon S3, buckets and objects can be created, listed, and retrieved using either a REST-style HTTP interface or a SOAP interface. The examples that ship with Jersey include a storage service example with a RESTful interface. The tutorial at http://netbeans.org/kb/docs/websvc/twitter-swing.html uses the NetBeans IDE to create a simple, graphical, REST-based client that displays Twitter public time line messages and lets you view and update your Twitter status.
