Debugging failed deploys

roguemonkey — Thu, 14 Aug 2014 21:08:47 GMT

I am trying to deploy a .bar file to the Activiti Explorer and I am getting an error.On the Activiti web-app, I get an "Error parsing XML" message, with no explanation.In my console log, I get a stack trace that is not a lot of help either : 04:56:34,959 [http-bio-8081-exec-2] INFO org.activiti.eng

Hi,

I created simple jUnit test. (https://github.com/martin-grofcik/activiti-unit-test-template/tree/forum-support-bpm-parse)

the problem was (several occurrences):


Caused by: org.activiti.engine.impl.juel.TreeBuilderException: Error parsing '#{trademark.analysisStatus)': syntax error at position 26, encountered ')', expected '}'

fixed property:


        <activiti:formProperty id="analysisStatus" name="Analysis Status" type="enum"
                               expression="#{trademark.analysisStatus}">

Regards
Martin

First of all, let me thank you for such a quick (and accurate!) answer.
If I may take one more second of your time, I'd like to ask : Is the normal process for developing a BPMN Diagram creating a unit test and running it to get the errors? Are there any plans to integrate validation and error reporting into the Eclipse Plug-In or the Activiti Explorer? How does a non-technical business analyst usually go about creating diagrams without running actual code?

Thank you very much for your time,
Alex

Hi Alex,

Good questions.

Is the normal process for developing a BPMN Diagram creating a unit test and running it to get the errors?

No. (log level, activiti explorer…, should report this kind of errors. (Isn't it possible to configure explorer…?)). Activiti explorer is only demo app. to show activiti features.

How does a non-technical business analyst usually go about creating diagrams without running actual code?

(validation should be part of the modeling tool - I am not using activiti process designer that's why I can not provide you more info.) Another question is testing - non technical business analyst should be able to test process definitions too. For such a requirements you can use simulation -> activiti-crystalball module.

Activiti explorer is only a demo app? I thought it was the actual production server in which users where supposed to run the processes. It does allow some management features which are handy… Do you mean to say that any production deployment should be done with an in-house application embedding the process engine? Does that mean that we are expected to develop management tools to stop, monitor, log the processes ourselves, instead of relying on the explorer to do it?

Thanks again for your time.
Alex

Hi Alex,

http://www.activiti.org/userguide/#activitiExplorer says:

The purpose of Explorer is not a finished, end-user ready application, but rather to excersise and show the functionality of Activiti. As such, Explorer is meant as a demo, or maybe inspiration for people using Activiti in there own applications.

Your question:

Does that mean that we are expected to develop management tools to stop, monitor, log the processes ourselves, instead of relying on the explorer to do it?

You can use explorer, if it you are satisfied with it.

Martin
