How to register custom ProcessEventListener

[wguo]

HI guys ,

    I created a custom ProcessEventListener and put the jar in */WEB-INFO/lib/ , and add eventListener from UI (add ksession then add the listener to the ksession)

<kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xmlns="http://jboss.org/kie/6.0.0/kmodule">

  <kbase name="KBase" default="true" eventProcessingMode="stream" equalsBehavior="identity" declarativeAgenda="disabled" scope="javax.enterprise.context.ApplicationScoped" packages="*">

    <ksession name="ksession" type="stateful" default="true" clockType="realtime" beliefSystem="simple" scope="javax.enterprise.context.ApplicationScoped">

      <listeners>

        <processEventListener type="com.domain.audit.CustomeProcessEventListener"/>

      </listeners>

    </ksession>

  </kbase>

</kmodule>

then begin to click 'build & deploy ' , it reported the following errors:

Caused by: java.lang.ClassNotFoundException: com.domain.audit.CustomeProcessEventListener from [Module "org.drools:main" from local module loader @751dc8af (finder: local module finder @7662953a (roots: /home/wguo/apps/jboss-eap-6.2/modules,/home/user/apps/jboss-eap-6.2/modules/system/layers/bpms,/home/user/apps/jboss-eap-6.2/modules/system/layers/base))]

anyone know the issues , thanks .

in 6.0.0.and 6.0.1 there was limitation to mvel based syntax when defining handlers in kmodule.xml so please use following instead:

<processEventListener type="new com.domain.audit.CustomeProcessEventListener()"/>

this has already been fixed to allow FQCN and will be available in 6.1.0

Hi Maciej ,

    That works , thanks .

    Btw , if i want to set global beforeProcessStart , how can i get current ksession in the method beforeProcessStarted ?  And  set some variable like requestor here ?

[swiderski.maciej]

beforeProcessStart method has an argument that is an event and from that event you can get KnowledgeRuntime which is actual ksession.
