Spring Webflow Plugin to Struts 2

[Cheng Wei Lee <zh...@gmail.com>]

Hi all,

I was trying out the SWF plugin from Google codes with the old example and
encountered some exceptions.

Got the example from https://issues.apache.org/struts/browse/WW-1525.

When I tried to enter the age, I got the following exception. I'd changed
the example.xml slightly to use the:
com.googlecode.struts2webflow.SessionFlowExecKeyInterceptor , and
com.googlecode.struts2webflow.FlowScopeInterceptor

And also, in the rating-flow.xml:

    <action-state id="AgeSave">
        <action bean="struts2FlowAdapter"/>
        <transition on="success" to="calcRate" />
    </action-state>

In the applicationContext.xml:
    <bean id="struts2FlowAdapter"
        class="com.googlecode.struts2webflow.Struts2FlowAdapter "></bean>

Thanks & regards,

Chengwei
