[jira] Commented: (WW-1388) Shopping Cart Example throws HTTP 500
[ http://issues.apache.org/struts/browse/WW-1388?page=comments#action_37860 ]
Don Brown commented on WW-1388:
-------------------------------
I noticed this as well. If no one steps up to maintain it, I'm inclined to remove it competely. I'd like to minimize the number of example applications we maintain, and it seems like any advanced AJAX shopping cart could just as easily be part of the showcase app.
