handle errors inside BaseStrutsPortletAction

[7年前 に Fabrizio Attanasio によって更新されました。]

Hello to all,
I implemented a hook for user creation. The flow is as follows:

- fill out the form jsp
- Join in the custom action, and here I make a call to an external service to check things. Also save data to an external database.
- The action continues with the originalStrutsPortletAction.processAction(originalStrutsPortletAction, portletConfig, actionRequest, actionResponse);
- At this point if there are any problems during validation (as check captcha text) I would like to make a rollback calling an external service to delete saved data on the external database.
How do I know that there were errors during the processAction?

Thank you,
Fabrizio

1. surround call with try/catch block.
2. check the SessionErrors object to see if any errors were added in the call to original struts portlet action.

In either case something was flagged that should trigger your cleanup code.

Thank you. I resolved with

if(SessionErrors.size(actionRequest)>0){
rollback etc...
}

Bye bye !
