Add Reactor plugin to Wildfly11 engine

Hi,

I am new to Camunda and I have to integrate camunda-bpm-reactor into my process engine. I am using wildfly11-7.10.0-alpha4 version.
There is an example in camunda-cfg.xml file but I am not sure how to modify that.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

  <bean id="processEngineConfiguration" class="org.camunda.bpm.engine.impl.cfg.StandaloneInMemProcessEngineConfiguration">
   <property name="processEnginePlugins">
     <list>
       <bean class="xxx.yyyy.bpm.parselistener.InformAssigneeParseListenerPlugin" />
     </list>
   </property>
  </bean>
</beans>

Could you please show me the steps.
