Documentation for Liferay Hooks

I need to listen for user log in and log out events in Liferay. From what little I've been able to find, it seems that using Liferay hooks would be the way to accomplish this. Unfortunately I haven't been able to find any information other that at the following link:

Does an开发者_JAVA技巧yone know where I can find further documentation or how I would implement listening for user log in/log out events?

Thanks in advance!

Your best place to start is probably:

http://www.liferay.com/community/wiki/-/wiki/Main/Portal+Hook+Plugins.

If you need to get started, you can use the SDK to create a new hook project, it'll give you a shell and the config XML:

Im covering Liferay hooks in this article I think it gives a good overview and Im sharing some catches I found out along the way in it as well.
