Hi,
I may have a requirement to audit all document downloads.
Presumably a download action could be made to add an entry into the
Event Log (History) for the document?
Yes, this is not the case by default but this can be added.
The usual way to add data into the event logs is :
- send an event on the Nuxeo standard topic (should be NXPMessages)
- add the needed config to audit so that the new event is logged
The real question is from where to send the event :)
If you are only interested in logging download from the webapp I see 3
solutions :
1 - You could add a filter on the download url.
Be aware that your filter must be behind the authentication filter if
you want to be able to create the JMS message.
2 - Another solution is to modify the file download codec (downloadFile
codec) so that it point to a "home made" Seam Bean that would send the
event and then forward the call to the standard Nuxeo one (
<actionBinding>#{documentActions.download}</actionBinding>).
3 - Another solution could be to override the Nuxeo Bean (ie : use Seam
@Install(precedence=APPLICATION)) by you own bean that derives from
Nuxeo one but sends the needed JMS event.
I would personaly vote for solution 2 since this make your dev
completely pluggable and this is quite simple.
For sending JMS events you can use the MessageProducer.
producer =
Framework.getService(DocumentMessageProducer.class);
Tiry
Any other/better ways?
Any reasons why this might be a bad thing to do?
Anyone that can point me in the direction of the relevant APIs to use?
Thanks,
Sean
