with an <code>InOut</code> Message Exchange Pattern.

completes the {@link WorkItem}. The use-case for this handler is

+ * The handler creates a Camel Exchange and sets the {@link WorkItem} as the
body of the {@link Message}. Furthermore, the following message

Review comment:
I guess these are used in the command as well so might be good to move them
to JBPMConstants

> Key: CAMEL-12964
> URL: https://issues.apache.org/jira/browse/CAMEL-12964
> Project: Camel
> Issue Type: New Feature
> Components: camel-jbpm
> Affects Versions: 2.23.0
> Reporter: Duncan Doyle
> Assignee: Maciej Swiderski
> Priority: Major
>
> The new camel-jbpm component allows CamelContexts and Routes to be defined on
> both a global (KIE-Server) and runtimeManager/deploymentUnit/KJAR level. A
> new CamelWorkItemHandler that integrates with these CamelContexts and routes
> would allow easy integration with external resources throuch Camel Components
> from within a process/case definition.
> See: https://issues.jboss.org/browse/JBPM-7995
