Apache Tuscany SCA : Error - cannot be resolved to a type

Hi,

I am a newbie in Apche Tuscany SCA. I am getting any error while running the
some components I have written in Apache Tuscany SCA. I will appreciate any
help on this error. Please let me know if you need more information.

Scenario 1: Success

If the Events Stasticts is directly called from a test.java, the code run
successfully.

Test.java

*EventsStatistics eventsStastics = scaDomain.getService(EventsStatistics.
class,"EventsStatisticsComponent");*

*
*

Scenario 2: Failure

I call the same file via .rf file (drool file) it throws me error:

*Process Compilation error : org.drools.lang.descr.ProcessDescr@3f3fbd*

*      kimstaff/ruleflow/Process_kimstaff_ruleflow_0.java (259:10381) :
EventsStatistics cannot be resolved to a type*

    <sca:implementation.java class="opennotus.ba.impl.EventsStatisticsImpl"

    <sca:service name="EventsStatistics">

      <sca:interface.java interface="opennotus.ba.EventsStatistics"/>

    </sca:service>

      <sca:interface.java interface="opennotus.ba.ExistAppConfig"/>

    </sca:service>

Thanks Ramond for your reply.

Yes, the EventsStastics is in the class path (it runs from Test.java). I can
show you the part of .rf file where this component (EventsStastics) is
called. Please find attached the .rf file daigram.
Below is the part of the code from .rf that calls EventsStastics

SCADomain scaDomain = (SCADomain) kcontext.getVariable("scaContext");

EventsStatistics eventsStastics =
scaDomain.getService(EventsStatistics.class,"EventsStatisticsComponent");

eventsStastics.createEvent("Kimstaff","HealthNet","CARRIERFILE", "HealthNet
Validation", discrepancyURL, "KimstaffEvents", "Discrepancies found!.",
"Serious",  (String) kcontext.getVariable("ofbizCustomerId"), (String)
kcontext.getVariable("ofbizPartnerId"));

CarrierStatsDTO carrierStats = (CarrierStatsDTO)
kcontext.getVariable("carrierStats");

eventsStastics.updateCarrierStat("Kimstaff","HealthNet",(String)
kcontext.getVariable("ofbizCustomerId"), (String)
kcontext.getVariable("ofbizPartnerId"), carrierStats.getSubscribers(),
carrierStats.getDependents(), carrierStats.getSuccesses(),
carrierStats.getFailures(), "Discrepancies found",
discrepancyURL,"verification", "", "WARN");

Hi,

It seems that you try to call Tuscany from the Drools flow. Can you show us the .rf file? Do you have EventsStatistics on the class path? You can also check if the kimstaff/ruleflow/Process_kimstaff_ruleflow_0.java has the fully-qualified class name of EventsStatistics?

Thanks,
Raymond
