Notifications api in liferay 6.2GA1

[janakisrinivas devalla, modificado hace 10 años.]

Hello Friends,

I want to use notifications which is plugged-in by default in lfy 6.2 ga1. We have already implemented our own service for notification which will be created our db.
I want to show those notifications using notification portlet . can anybody know How to use this notification api to display our custom notifications.

I haven't tried it yet, but if I'm right, you can check the source code of the chat portlet to see it's usage (if I'm right and you think about that notification mechanism)

Cheers,
Vilmos

Hello Vilmos ,
Thanks for the reply. I have gone through the chat portlet source code I did not find use of notfications portlet.
I have to show notifications of portal logged in user in the portal dockbar notification area.
What I am thinking is I have to get our notification object of a user from my service and add it to the liferay database using notification api addXXX methods.

If this correct please give some sample code how to call those API's. If I am wrong suggest me the alternative approach How to do that.

You can write the logic in dockbar portlet of view.jsp (html\portlet\dockbar) by getting from your service which can be accessed globally and add into liferay Alert / Announcement Service APIs.

Hi,

Sorry, I misunderstood what you were searching for. I checked it but I'm not familiar with that framework yet.

Hi Tonmoy ,

You must create custom class CustomUserNotificationHandler extends BaseUserNotificationHandler
and declare it in liferay-portlet.xml :
<user-notification-handler-class>xxx.xxx.CustomUserNotificationHandler </user-notification-handler-class>

I wrote a short tutorial about how to handle custom notifications in Liferay 6.2. While it might not be perfect it's better than any other data I found using Google. I spent a lot of time reading the Liferay source code to understand properly how the notification system is working. In short, you need to define you "user-notification-definitions" and "user-notification-handler-class" in liferay-portlet.xml. Then you need to actually implement those properly. Also there's an important catch that "notification-type" has to actually be a valid Portlet ID, otherwise you start getting random NullPointerExceptions.

You can read the full tutorial here:

Good luck!
