Hi Matt,
Thanks for the reply.
I'd tried previously with a debugger without success.
What it had told me is that nothing I could do would make Struts call my list
method, the superclass' execute() method
was called instead.
In the end, I did the following and now it works. Not sure whether all changes
were needed and I don't have the time to
experiment now:
1. Changed my DeliveryTonnageAction class to lose the "list()" method and
override "execute()" and call my
crosstab-building method from that.
2. Changed the Struts.xml definition to the following:
<action name="tonnage" class="deliveryTonnageAction">
<result>WEB-INF/pages/deliveryTonnageList.jsp</result>
<result name="cancel" type="redirect">deliveries.html</result>
</action>
What's different about two is:
a. Action name is changed from "deliveryTonnage" (IIRC)
b. removed the 'method="list"' attribute from the action tag so it
defaults to "execute()" (which is what it was doing
anyway - I just went with the flow!
c. Added the "cancel" result, because I needed that anyway.
Now it all works so I'm happy, though I'd be just that little bit happier if I
understood exactly what was wrong and how I
fixed it :-( Maybe later I'll have the time to experiment.
