The Spring 2.0 Way

Interface21 added support for session (and request) scoped beans in Spring 2.0. This approach creates a CGLIB or JDK Dynamic proxy of the session scoped bean using the org.springframework.aop.target.scope.ScopedProxyFactoryBean and setting the scopeMap to org.springframework.web.context.scope.SessionScopeMap.

Since the jars are backwards compatible simply build spring Spring and replace the jars shipped with WebWork. (Spring 2.0 M1 should be out by the time you read this.).

Custom TargetSource with a ServletFilter

A quite "clean" solution for web applications in general can be found at JA-SIG. The solution is well documented and can be found here. Below you will find a WebWork adoption of this solution.
