Hi

It worked by adding inbuilt camel queues as shown in the example. I thought they were just shown as example for various routes. But by passing to queue actually the ServiceTask was made asynchronous in camel and later from queue they were read and invoked the receive task in activiti

    <camel:to uri="seda:tempQueue"/>
    <camel:from uri="seda:tempQueue"/>

Thanks

Thanks for your detailed stackoverflow post, but would it be possible to create a unit test so we can reproduce it easily?

Best regards,
