Callback or event for my application

[msj4u]

Hi,

I have integrated alfresco for document uploading with my application using web-services;

Now I want to trigger a callback to my application for deleting the file from alfresco web client so that i can sync my application.

Any ideas how to do that

You can write a behaviour class, that implements  "beforeDeleteNode" policy  and in your behaviour class call your application's webservcie to delete node in your application.

where can i find this behavior class interface or already implemented classes ?
