Issue with creating processEngine instance using ProcessEngineConfiguration.buildProcessEngine

[rajeshbabu_naid]

Hi,

I'm trying to upgrade from activiti 5.10 to 5.12 to use reports capability but i'm facing an issues while trying to start a custom BPMN process using activiti API.

Below is the java code that i'm using and this was working with 5.10. Please help me.

                                ProcessEngine processEngine = null;
      ProcessEngineConfiguration config = null;
      
      try {
         config = ProcessEngineConfiguration.
               createProcessEngineConfigurationFromResourceDefault();
      } catch (Exception e) {
         e.printStackTrace();
      }
      
      if (config != null) {
         try {
                         processEngine = config.buildProcessEngine();
         } catch (Exception e) {
            e.printStackTrace();
         }
      }

Below is the activiti.cfg.xml

Hello mmaker1234,

I couldn't see any error/exception on my console but nothing is happening after executing the below line while debugging. The control i simply disappearing from my Eclipse.

processEngine = config.buildProcessEngine();

Hi Team,

can you please help me on this?

[trademak]

The description is really vague, please add more details. Can you create a unit test project that reproduces your problem?
Do you for example have the org.activiti.explorer.form.UserFormType class on your classpath?

Best regards,
