Hi, I've a related question.
When I try to import a bpmn file exported from other BPMN 2.0 compliant systems [like iGrafx or BlueWorksLive(BWL)], the modeler throws this error message "Import Failed". First of all, the modeler throws two error messages one on top of the other & so not readable at all. I've to click over it to get rid-off the error message thrown on top to see the earlier error message. [I've the screenshots if you'd want me to send to you. I can not attach them here as only .txt file is allowed.]

When I check the catalina log, I get this NullPointerException message in the log:

Can you please help out on that?

We use Activiti version 5.15.

PS: If I try to export a process definition with bpmn2.0 format & import back between iGrafx & BWL, they work fine. Also, exporting a natively defined process definition in Activiti modeler & importing onto iGrafx & BWL also seem to work fine.

Thanks very much.

Could you provide the BPMN XML file as well?

Thanks,

Not able to import these files in Activit 5.14

Seems to deploy fine, but the Explorer UI throws an error… Can you try deploying the file through the API (managementService.createDeployment().add…)?

Hi Frederik,

Thanks for the reply.

Following is the error in Catalina.out . If it is deploying correctly , then it should list in the deployed process definition right?. it is not listing.
Can u help us to resolve the UI error . I will try with code meanwhile

When I check the catalina log, I get this NullPointerException message in the log:

It's deploying correctly, but the request that originated the deployment API-call thaws an exception, effectively rolling back the transaction (and the deployment of the process). Seems that the modelData is null -> can you set the isExecutable attribute on the process to true? Activiti only "deploys" executable processes, the rest are ignored. The Explorer UI import expects an executable process…

Hi Fred,

Thanks for the reply
I have deployed the Initial Project Plan.bpmn
and KYC Process - Asset Ser_AIS_GM_GCM.bpmn with isExecutable="true". But it is the same error in the catalina.out as mentioned above.
In the UI , when I import KYC Process - Asset Ser_AIS_GM_GCM.bpmn , it says "Could not import file only .bpmn or .bpmn20.xml files are supported". When I import Initial Project Plan.bpmn it says two warnings overlapping each other. 1) "Could not import file only .bpmn or .bpmn20.xml files are supported" 2) Could not find BPMN DI information . Make sure file contains BPMN DI Information""
Both the file has filetype .bpmn as extension.

Thanks
George

Hi Fred,

Just want to clarify that activiti 5.14 is having automatic layout module. Does it require BPMN DI in the model . Without this will it not import the file.?

Thanks
George

If you want to import a file into the MODELER, you need DI-information. There is no auto-layouting going on there. Deploying such a process to the engine itself (using either REST or java API) should work just fine. If you want to edit the process in the modeller, you'll have to run it through the auto-layout module first. See http://stacktrace.be/blog/2013/03/dynamic-process-creation-and-deployment-in-100-lines/ - instead of making a model in Java, you just need to deploy the bpmn20.xml, get the Model pogo from it and run it through the auto-layout…

Thanks Frederick,

I ran the following code with activiti 5.16
try
   {
    ProcessEngine processEngine = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource(CONFIG_FILE).buildProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    Deployment deployment = repositoryService.createDeployment()
      .addClasspathResource("InitialProjectPlan.bpmn20.xml")
        .disableBpmnValidation()
        .disableSchemaValidation()
         .deploy();
    System.out.println("Name >>" + deployment.getName() + "ID >> " + deployment.getId());
   }
   catch(Exception ex)
   {
    ex.printStackTrace();
   }

I have used disableBpmnValidation() and disableSchemaValidation() to pass thru deployment . otherwise it is not allowing to deploy through this code. I have attached Initial Project Plan.bpmn20.xml . ran this with isExecutable="true". After this it was allowing to deploy because not able to find the import type.

Following is the error
org.activiti.engine.ActivitiException: Could not import item of type http://www.omg.org/spec/BPMN/20100524/MODELorg.activiti.engine.ActivitiException: Could not import item of type http://www.

        at org.activiti.engine.impl.bpmn.deployer.BpmnDeployer.deploy(BpmnDeploy

=============
So I commented all the import lines and tried to deploy . Now I was able to deploy and it is loaded in the process definitions
But diagram is not displayed and not able to edit the model because the Button is disabled.

1) Where you able to deploy the attached file(without bpmndi xml tags) through the code and see the diagram and able to edit the model?
Please help me in this regard to solve the problem

Thanks In Advance
George
