[Building Sakai] Wicket and entity broker

[Tania Tritean]

Hello,

I need to call a EntityCustomAction from a wicket tool. Can anybody please tell me how can I do that?

In the tool I have a page, on the submit button of the form from that page I want to call the method annotated with EntityCustomAction.
The method can throw different exceptions that I need to handle in UI.
 Is there a 'rest client' in sakai that I can use for this with wicket?

Thanks in advance,

Tania
