Hello all,

I have implemented diameter-openims example in mobicent-jainslee 2.7.0.
I saw that only SNR, SNA, PNR and PNA worked in this example.
SNR and SNA worked when Jboss started
then PNR PNA worked when there is call from alice to bob

So, If I want to send UDR from AS to HSS,
What event that UDR will be sent to HSS? and
What class or file that will be a triger for this action, because for now I just learn that, only SNA,PNR, UDA, PUA have registered on sbb-jar.xml and event-jar.xml.

Best Regard

Hi Yessica,

Have a look at http://docs.jboss.org/mobicents/jain-slee/2.7.0.FINAL/resources/diameter-sh-client/user-guide/en-US/html_single/#ratype_sbb_code_examples it has an example. Try to go through docs, there are many things which are explained there ;)

Hi, Alex,
When I tried the example doSimpleTestsSendUDR, appeared this error because of failed casting:

       INFO [DiameterShClientResourceAdaptor] (pool-29-thread-1) Activity started [Diameter Session ID[mobicents.open-ims.test;324;3480042490]]

So, I changed
       UserDataRequest udr = ((ShClientMessageFactory)basicClientActivity.getDiameterMessageFactory()).createUserDataRequest();

into
       UserDataRequest udr = ((ShClientMessageFactory)basicClientActivity.getClientMessageFactory()).createUserDataRequest();

But, appeared another error

I found it,
the problem is because,
          avps.add(avpFactory.getBaseFactory().createAvp(Avp.DESTINATION_HOST, ("aaa://" + destinationIP + ":" + destinationPort).getBytes() ));
          avps.add(avpFactory.getBaseFactory().createAvp(Avp.DESTINATION_REALM, destinationRealm.getBytes()));
that result :
            DESTINATION_HOST : aaa://127.0.0.1:3868
            DESTINATION_REALM : open-ims.test

and the correct one is :

avps.add(shAvpFactory.getBaseFactory().createAvp(Avp.DESTINATION_HOST, (destinationHost != null ? destinationHost.getBytes() : ("aaa://" + this.destinationIP + ":" + this.destinationPort).getBytes())));
avps.add(shAvpFactory.getBaseFactory().createAvp(Avp.DESTINATION_REALM, this.destinationRealm.getBytes()));

that make result :
DESTINATION_HOST : hss.open-ims.test
DESTINATION_REALM : open-ims.test

I confused, because for me, hss.open-ims.test is same with aaa://127.0.0.1:3868
Am I lacking something to configure?

Nop, you're not lacking any config. But destination-host cares about the name, not what it resolves to.. and also, it should not be a uri (such as aaa://127.0.0.1:3868) but a FQDN (like hss.open-ims.test ). The example is not very accurate on that matter.
