Apache camel Activiti OSGI和Blueprint的问题

我尝试在KARAF OSGI中使用Activiti和camel

我从服务组合配置中复制了一些部分

我可以在容器中毫无问题地部署捆绑包。当我使用camel模块触发工作流时，会出现以下异常：

2016-11-08 11:56:43569 | ERROR | m://client_queue | JobsBpmnProducer |45-作业日志记录-1.0.0 |找不到与此相关的Processdefinition 标识符ActivityException:应为 Activiti Camel模块的SpringProcessEngine配置。

如何使用spring部署符合OSGI的Processengine以使Camel正常工作？

此问题可能已在活动代码中得到解决。 看

您能试用最新的Activitiy版本吗？

解决方案包含的任何理想版本？我使用5.19.0.45.19.0在问题解决后发布。所以你的版本可能会包括它。我仍然会给最新版本一个旋转来检查。看看Activiti代码，这个问题没有解决，@ChristianSchneider提到的pr确实解决了一个ClassCastException，但不是这个。。查看代码[1]，CamelBehavior总是期望SpringProcessEngineConfiguration（第197行）。1:Hey@Brampouwels这告诉我在OSGI上下文中不可能使用Camel？@MarcelWolf认为你是对的，这是不可能的，Activiti文档[1]也提到了Spring依赖性。1：解决方案包括哪些理想版本？我使用5.19.0.45.19.0在问题解决后发布。所以你的版本可能会包括它。我仍然会给最新版本一个旋转来检查。看看Activiti代码，这个问题没有解决，@ChristianSchneider提到的pr确实解决了一个ClassCastException，但不是这个。。查看代码[1]，CamelBehavior总是期望SpringProcessEngineConfiguration（第197行）。1:Hey@Brampouwels这告诉我在OSGI上下文中不可能使用Camel？@MarcelWolf认为你是对的，这是不可能的，Activiti文档[1]也提到了Spring依赖性。1:
