WebWork is a powerful web-based MVC framework built on top of a command pattern framework API called XWork. The true power of Webwork is its underlying concept of simplicity and interoperability. Using WebWork will help minimize code and allow developers to concentrate more on business logic and modeling, rather than the plumbing often required when building web-based applications.

Features

• A flexible Validation framework allowing you to decouple validation rules from your action code.
• Type Conversion allowing you to easily convert objects from one class to another, solving one of the most tedious efforts when creating web apps.
