how to pass Map in camel context in jbpm component - apache-camel

Question

look at the location JBPMComponentIntegrationTest
.setHeader(JBPMConstants.PARAMETERS, constant(map))
so them map is passed as map in java route.
If i want to pass the same via xml is there a way ?
<camel:setHeader headerName="CamelJBPMParameters">
<camel:constant>????</camel:constant>
</camel:setHeader>
I could not find any example over internet.

If you are using a spring context you could simply initialize the map then reference it in your constant file. I am not 100% familiar with the xml camel constructs but it should look similar to this:
<camelContext id="myContext" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="direct:start"/>
<setHeader headerName="theHeader">
<!-- not sure if the ref keyword is valid might have to adjust syntax -->
<constant ref="maps" />
</setHeader>
<to uri="mock:result"/>
</route>
</camelContext>
<property name="maps">
<map>
<entry key="Key 1" value="1" />
<entry key="Key 2" value="2" />
<entry key="Key 3" value="3" />
</map>
</property>
