Access Portal Services within Web Dynpro

Question

Hi,
I created a portal service and would like that some values of the same have to be set by a Web Dynpro application, but i have a problem to access this
service. Always that a i try to get a reference of this service the object isn't instantiated and i get a null instantiated.
What i`m trying to do is the broadcast message described in [/people/prakash.singh4/blog/2005/04/28/brodcast-messages-to-logged-on-users-in-portalpart1 |/people/prakash.singh4/blog/2005/04/28/brodcast-messages-to-logged-on-users-in-portalpart1]with a variation that need of some
more Attributes and that the same will be pass by the Web Dynpro, like the broadcast message i`ll just use the alert concept and don't the publication.
Follow below the describe of executed actions.
1 - I did all the process as the [Weblog|/people/prakash.singh4/blog/2005/04/28/brodcast-messages-to-logged-on-users-in-portalpart1].
2 - I generated the Jar and insert the same in a DC.
3 - I generated the Web Dynpro application, in the used DCs and added the DC with the Jar, and i inserted the reference in a Sharing References. 
4 - Did the deploy and insert the Web Dynpro in a Portal Iview.
But always that i execute, i can't capture the reference of the service.
Note: The reference in Sharing References was executed for several diferents forms of test, like for exemple:
PORTAL:<vendor>/com.teste.broadcast
PORTAL:com.teste.broadcast
PORTAL:<vendor>/com.teste.broadcast.alertreceiver
PORTAL:com.teste.broadcast.alertreceiver
But always adding one at a time.
Until put the saller like sap.com i already try.
The creation of the service as described in the weblog can be accessed for a Web Dynpro? What the problem to access the Service??
The codes follow Bellow.
