Access Portal Services within Web Dynpro

[Former Member]

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.

portalapp.xml

<?xml version="1.0" encoding="UTF-8"?>
<application>
  <application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb,com.sap.portal.runtime.system.notification"/>
    <property name="ServicesReference" value="com.teste.broadcast"/>
  </application-config>

...

  <services>
    <service name="alertreceiver">
      <service-config>
        <property name="className" value="com.teste.broadcast.alertreceiver"/>
