how to pass Map in camel context in jbpm component

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>
