java.io.NotSerializableException: org.activiti.engine.impl

[cweber]

Hi. I am trying to use the activiti engine (5.9 or 5.10) with a jsf + primefaces gui on a Apache Tomcat 7.
I created a java managed bean which created the engine and it works so far that I could get the first tasks for a user.

But I ever get the following error:
SCHWERWIEGEND: Exception loading sessions from persistent storage
java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.activiti.engine.impl.IdentityServiceImpl

Isn't it possible to serialize this class? Is there another way to use the identity service in jsf managed beans?
Thanks for help.

My jsf is a bit rusty, bit are managed beans the right place to store it?

The process engine and it services are thread safe, and the best way is to store it somewhere central, not in a managed bean, right?

Use activiti-cdi… Perfect fit with jsf.

Thanks for answearing. I'll give cdi-beans a try.

By any chance using Primefaces? A cweber active there as well…

[cweber]

Yes, I'm there, too.

I'm starting to search for a good possibility to create a gui around the activiti engine. And that is why I start testing JSF with Primefaces. Are you envolved in the Primeface development?

kukeltje in the primefaces forum… And no, I'm not developing Primefaces… But yes, I'm currently looking into extending the primefaces datatable with tree functionality, auto-height, a nice search button (or hiding the search filters) and more… Stay tuned over the weekend.

Btw, the Camunda Fox cockpit is developed in JSF/Primefaces. Maybe some ideas there…?
