Activiti OSGI和Blueprint的問題

Question

我嘗試在KARAF OSGI中使用Activiti和駱駝。

我從服務組合配置中複製了一些部分。

     <from uri="vm:client_queue"/> 
     <to uri="jobsbpmn://bpmn"/> 
    </route> 
</camelContext> 

我可以在對容器的問題部署包。當我用駱駝模塊觸發工作流程時，我得到這些異常：

2016-11-08 11：56：43,569 |錯誤| m：// client_queue | JobsBpmnProducer | 45 - 作業記錄 - 1.0.0 |沒有ProcessDefinition與此 標識符ActivitiException：期望 Activiti Camel模塊的SpringProcessEngineConfiguration。
ClassCastException異常： org.activiti.engine.impl.cfg.JtaProcessEngineConfiguration不能 投地org.activiti.spring.SpringProcessEngineConfiguration **

我如何可以部署使用OSGI春天讓駱駝符合流程引擎工作？

此問題可能已在活動代碼中得到解決。 請參閱https://github.com/Activiti/Activiti/pull/519

您可以試用最新的Activitiy版本嗎？
