Tapestry divides a Web application into a set of pages, each constructed from components. This provides a consistent structure, allowing the Tapestry framework to assume responsibility for key concerns such as URL construction and dispatch, persistent state storage on the client or on the server, user input validation, localization/internationalization, and exception reporting. Developing Tapestry applications involves creating HTML templates using plain HTML, and combining the templates with small amounts of Java code using (optional) XML descriptor files. In Tapestry, you create your application in terms of objects, and the methods and properties of those objects -- and specifically not in terms of URLs and query parameters. Tapestry brings true object oriented development to Java Web applications.
Tapestry is specifically designed to make creating new components very easy, as this is a routine approach when building applications. The distribution includes over fifty components, ranging from simple output components all the way up to complex data grids and tree navigators.
Tapestry is architected to scale from tiny applications all the way up to massive applications consisting of hundreds of individual pages, developed by large, diverse teams. Tapestry easily integrates with any kind of backend, including J2EE, HiveMind and Spring
