Configure a Bean in an XML file

Hi,

I'm working with some software (Camunda comunity edition).  It's a process engine for handling processes which have been written in BPMN.  It also has a DMN (Decison Management Notation) engine which integrates into the process engine.  The instructions on how to configure the   engine are based on either using the Java API or Spring XML.  

This isn't the only way to configure the process engine as another method they have is through another XML file.  So I'm sort of halfway to taking what they have written for the Spring XML file example and converting it to my example there is just a small question about how one of the properties should be specified in the BPM-server.XML file.

It's easier to visualise, so let me paste the actual code.

The example from their documentation here

<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.StandaloneProcessEngineConfiguration">
  
    <property name="dmnEngineConfiguration">
      <bean class="org.camunda.bpm.dmn.engine.impl.DefaultDmnEngineConfiguration">
        
        <!-- configure the DMN engine ... --> 
        <!-- e.g. set the default expression language for input expressions to `groovy` -->
        <property name="defaultInputExpressionExpressionLanguage" value="groovy" />
        
      </bean>
    </property>
    
  </bean>
</beans>

Select allOpen in new window

I had the following in my bpm-server.xml file (extract):-

  <job-executor>
    <job-acquisition name="default" />
  </job-executor>

  <process-engine name="default">
    <job-acquisition>default</job-acquisition>
    <configuration>org.camunda.bpm.engine.impl.cfg.StandaloneProcessEngineConfiguration</configuration>
    <datasource>java:jdbc/ProcessEngine</datasource>

    <properties>
      <property name="history">full</property>
      <property name="databaseSchemaUpdate">true</property>
      <property name="authorizationEnabled">true</property>
      <property name="jobExecutorDeploymentAware">true</property>
    </properties>

    <plugins>
  

Select allOpen in new window

So I basically added a property for the DMN Engine within the properties section like so:

	  <property name="dmnEngineConfiguration">org.camunda.bpm.dmn.engine.impl.DefaultDmnEngineConfiguration</property>

Select allOpen in new window

However where would I put the property for setting the expression language to Groovy?  Would this go in the properties section along with the DMN Engine configuration property?  and if so how would it look like?

This is going to be very easy for anyone who knows how!
