Spring Web Flow 1st preview release is out

We are pleased to
announce a preview release of Spring Web Flow for use with the Spring
1.2 release path.  With this release, we consider the web flow
system fit for development use.

Contained in this release are new features we expect to take web
applications with demanding page flow requirements to the next
level.  These include:

  • The ability to capture the logical
    page flows of
    your application as self-contained modules reusable in multiple
  • The ability to nest flows ‘n’ levels
    deep (as
    subflows), where each flow is a "black-box" adhering to a well-defined
    contract for input/output.
  • The ability to express page flows
    with a pluggable flow definition format (currently Java-based and
    XML-based builder formats are provided.)
  • The ability to affect the path
    through a flow in a
    dynamic fashion by reasoning on contextual data in any supported scope.
  • The ability to track and respond to
    the lifecycle
    of a page flow.
  • Automatic state management with the
    ability to
    store model data in several scopes (event, request, flow)
  • The ability to centralize related
    action logic
    associated with a flow in one class.
  • Support for application transaction
    synchronization, using a token-based mechanism.
  • No hard-wired dependency on HTTP
    request/response or any request URL, for use in other environments like
    Portlets, JSF, and Tapestry.
    - An expired flow detector, for automatic cleanup of abandoned flows.
  • Out of the box helper actions for
    form data binding
    and validation.
  • Out of the box Struts 1.x
    integration (sample
  • Out of the box Spring MVC
  • Designed for extensibility, with
    plug-in points for customization (custom state types, custom flow
    builders, etc.)

And as always, with the Spring seal of quality you?ve come to expect,
we offer:

  • Quality documentation, both in the javadocs and
    forthcoming reference docs
  • Strong test coverage
  • Careful attention to naming, packaging, and ease of use
  • Exceptional error reporting
  • A feature set driven by end user

To download the preview release:

  1. Access the springframework project file list
  2. Scroll down to the ‘spring-webflow’ release package
    and select ‘’ for download.

The release archive consists of two jars:

  1. spring-webflow.jar - the core web flow system
  2. spring-webflow-support.jar - supporting packages not
    yet released as
    part of the core Spring framework.

As the release archive does not ship with the Spring Framework, please
download Spring 1.2 RC1 first if you have not done so already.

Once downloaded, visit the webflow
to review the module documentation and "Quick Start."

To get a good feel for Spring Web Flow in action, checkout the samples
in the release archive within the samples/webflow directory.  See
the samples/webflow/readme.txt file on how to build and deploy the
sample applications.
We very much value your feedback, and hope you enjoy using Spring Web
Flow as much as we have enjoyed bringing it to you.
