topic Activiti + Camel in OSGi: problem with imported packages in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/activiti-camel-in-osgi-problem-with-imported-packages/m-p/149038#M104057 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><SPAN>&nbsp;&nbsp; first of all, I have to say that you are doing an excellent work <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></SPAN><BR /><BR /><SPAN>&nbsp;&nbsp; I have implemented a couple of business processes in Activiti. Those processes use a pair of Camel routes by using the corresponding Camel tasks as described in the user guide. It works pretty fine in the unit tests implemented to validate it.</SPAN><BR /><SPAN>&nbsp;&nbsp; I have deployed it in an OSGi container with the following bundle constellation:</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * activiti engine bundle</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * activiti spring bundle</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * activiti camel bundle</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * activiti osgi bundle (implementing the extender which searches for bpmn files and deploys them in the engine)</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * bundle1which instantiates the engine and exports it as an OSGi service. The activiti services (runtime, task, repository, etc.) are exported as well.</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp;&nbsp; * bundle2 containing the process definitions.</SPAN><BR /><BR /><SPAN>&nbsp; When this constellation is deployed, the extender finds correctly the process definitions and tries to deploy them. Unfortunately, I get an error during the process as there seems to be some problems with the classloader restrictions in the OSGi environments.</SPAN><BR /><SPAN>&nbsp; The error I get is:</SPAN><BR /><BR /><SPAN>Unable to deploy activiti bundle </SPAN><BR /><SPAN>org.activiti.engine.ActivitiException: Errors while parsing:</SPAN><BR /><SPAN>Could not find org.activiti.camel.CamelBehavior: org.activiti.camel.impl.CamelBehaviorDefaultImpl not found by org.activiti.engine</SPAN><BR /><BR /><SPAN>It is caused because the activiti-engine bundle has no visibility of the packages exported by the bundle activiti-camel.</SPAN><BR /><SPAN>As a workaround I have created a bundle defined as a fragment of the activiti-engine bundle that imports the packages exported by activiti-camel (in fact uses Require-Bundle) but this is nothing else than a dirty workaround. I think the elegant solution is that the activiti-engine bundle imports the packages exported by the activiti-camel bundle with the flag for optional requirement.</SPAN><BR /><BR /><SPAN> Can you please consider include this change in the next version? In case you think that this is not a proper solution can you please provide me some hints on why?</SPAN><BR /><BR /><SPAN>&nbsp; thanks a lot</SPAN></BODY></HTML> Mon, 23 Sep 2013 20:02:03 GMT ojdiez 2013-09-23T20:02:03Z Activiti + Camel in OSGi: problem with imported packages https://connect.hyland.com/t5/alfresco-archive/activiti-camel-in-osgi-problem-with-imported-packages/m-p/149038#M104057 Hi,&nbsp;&nbsp; first of all, I have to say that you are doing an excellent work <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span>&nbsp;&nbsp; I have implemented a couple of business processes in Activiti.
