viewing process def in explorer when process definition deployed using bpmn file thorugh java program

[knishant14]

Hi,

I have deployed and run process definition through java program in eclipse. I have the bpmn file in my project resource folder. My code uses activiti apis to deploy and run the process definition though a junit test case.

Now i am trying to see the process definition in activiti explorer which is pointing to same database as my stand alone java application does.

I can see the process definition in the list of processes in Activiti Explorer. But when i click on it it gives me error:-

I can also see the process instance in the list of completed process instance.

Is there more stacktrace? The root cause seems to be missing from this one.

[knishant14]

it got resolved when i switch to programatic deployment from spring deployment. I dont know why in spring deployment deployment id is having value "null" in GE_bytearray table.

But now i am facing another issue with duplicate filtering. i have enabled like this.

repositoryService.createDeployment().name(processDefinitionName).addClasspathResource("resources/processflow/activiti/modified.bpmn20.xml").enableDuplicateFiltering().deploy();

But every time when i run a junit test case it does a new deployment. Am i missing something?

Please suggest.

And you are sure your unit test doesn't clean up the deployments?

Do you see two entries in your database table with the same name?

Duplicate filtering should avoid that a process with the same name and xml is deployed twice.

Sorry for delayed reply.

It got resolved.

Thanks
