I checked many forums. All i get is that, with a simple change in portal.properties file we can enable esb in liferay 4.1 or liferay 5.2 but not in higher versions.
You can create portlets that publish to your ESB and portlets that consume messages from the ESB (we have one that receives incoming messages and pushes to the LMB where a specific user instance of the portlet will consume messages).
As far as integration goes, I don't know what you're looking for exactly...
I want to either consume the services provided by liferay in my custome portlet or want liferay to consume my services. I am not even aware of the services provided by liferay. Just read in some posts about liferay services.
It would be very helpful if someone can provide some links where i can increase my knowledge about liferay's along with its web service related features.
Note: I am learning liferay. So this question might seems to be silly.
