Hi
You are trying to catch wrong type of event.
Please use
"net.java.slee.resource.diameter.ro.events.RoCreditControlAnswer"
instead of "net.java.slee.resource.diameter.base.events.ReAuthAnswer"
Regards

Sorry, I misread your problem.
What is exactly the scenario ?
Which way are you sending ReAuthRequests ?

Hello,
This is a piece of code that send reAuthRequest, for abortRequest code
is almost identical:

RoServerSessionActivity roActivity =
getServiceData().getRoServerSessionActivity();

ReAuthRequest reAuthRequest =
roActivity.getDiameterMessageFactory().createReAuthRequest();

reAuthRequest.setDestinationHost(getServiceData().getRoCreditControlRequest().getOriginHost());

reAuthRequest.setDestinationRealm(getServiceData().getRoCreditControlRequest().getOriginRealm());

long rg =
getServiceData().getRoCreditControlRequest().getMultipleServicesCreditControls()
[0].getRatingGroup();
DiameterAvp rgAvp =
roActivity.getDiameterAvpFactory().createAvp(432, rg);
reAuthRequest.setExtensionAvps(rgAvp);

if
(getServiceData().getRoCreditControlRequest().getMultipleServicesCreditControls()
[0].getServiceIdentifiers() != null
&&
getServiceData().getRoCreditControlRequest().getMultipleServicesCreditControls()
[0].getServiceIdentifiers().length > 0)
{
long srvId =
getServiceData().getRoCreditControlRequest().getMultipleServicesCreditControls()
[0].getServiceIdentifiers()[0];
DiameterAvp srvIdAvp =
roActivity.getDiameterAvpFactory().createAvp(439, srvId);
reAuthRequest.setExtensionAvps(srvIdAvp);
}
reAuthRequest.setUserName("test");

roActivity.sendReAuthRequest(reAuthRequest);

My app acts as server which receives charging requests from GGSN.
After credit limit is recharged ReAuthRequest is send to GGSN for
reauthorization. Response from GGSN is kind of an error type, I get
ReAuthAnswer with RC - DIAMETER_COMMAND_UNSUPPORTED, so maybe this
could be related with this issue. Btw, aci is attached by SBB, so
should be no problem here. Same happens to AbortSessionResponse which
also it has RC - DIAMETER_COMMAND_UNSUPPORTED, so maybe RC code is
somehow related to this issue. Below is event declaration for
ReAuthRequest and AbortSessionRequest, in first post i accidentally
copied piece of declaration for RoCreditControlRequest, sorry.

<event event-direction="Receive" initial-event="False">
<event-name>ReAuthAnswer</event-name>
<event-type-ref>
<event-type-
name>net.java.slee.resource.diameter.base.events.ReAuthAnswer</event-
type-name>
<event-type-vendor>java.net</event-type-vendor>
<event-type-version>0.8</event-type-version>
</event-type-ref>
<initial-event-select variable="ActivityContext"/>
</event>

<event event-direction="Receive" initial-event="False">

<event-name>AbortSessionAnswer</event-name>
<event-type-ref>
<event-type-
name>net.java.slee.resource.diameter.base.events.AbortSessionAnswer</

event-type-name>
<event-type-vendor>java.net</event-type-vendor>
<event-type-version>0.8</event-type-version>
</event-type-ref>
<initial-event-select variable="ActivityContext"/>
</event>

Thanks,
Robertas

I found the issue - it was wrong application id. Another problem is
that for ReAuthRequest base diameter factory does not allow adding it,
thought it does for AbortSessionRequest.

I had modified source code of:
org.mobicents.slee.resource.diameter.base.DiameterMessageFactoryImpl.java

public ReAuthRequest createReAuthRequest(DiameterAvp[] avps) throws
AvpNotAllowedException {
ApplicationId appId = getApplicationId(avps);
ReAuthRequest msg = (ReAuthRequest)
this.createDiameterMessage(null, avps, Message.RE_AUTH_REQUEST, appId !
= null ? appId : BASE_AUTH_APP_ID);

// Add Session-Id AVP if not present
addSessionIdAvp(msg);

return msg;
}

So this is same as for AbortSessionRequest, applicationId is retrieved
from provided avps[] array. What should I do this updated code, should
i send it so someone or you will update it in repository?
Just an idea for improvment - maybe it could be added automatically
depending on specific implementing RA type, like "4" for Diameter Ro
Ra in similar manner as sessionId is added?

Another problem - from Huawei GGSN AbortSessionAnswer comes without
AuthAppId it has VendorSpecificAppId instead(inside is correct
AuthAppId avp), I think because of this missing AuthAppId avp event is
not routed back to service and is filtered as previously - ra expect
events according to application id.

You can create an issue here: http://code.google.com/p/mobicents/issues/entry?template=Mobicents%20Diameter%20Template and attach the patch, we will review and apply it.

I think that's the best option, as well. The specific message factory should override the method to include proper Application-Id. If you can, please provide such changes.

You can add the specific Application-Id to the RA, so that it will listen to the custom application id. See http://docs.jboss.org/mobicents/jain-slee/2.5.0.FINAL/resources/diameter-ro/user-guide/en-US/html/ra.html#ra_configuration
