activiti workflows

ggoutham

Hi all,
I want to know how to create a activiti workflow i have downloaded the activiti 5.11 plugin for eclipse but i am unable to get the idea to work with it and how to deploy the workflow created with extension .bpmnd.
i read the jeff potts workflow tutorial but that is for old versions of activiti and alfresco.

Kindly help me in this regard

Thanks in advance

Do you want to deploy it in Alfresco only?
If yes then I do not think there are much changes in the deployment methods.
what is the issue you are facing if you follow that tutorial?

ggoutham

Hi,
Thanks for your reply
First of all i want to know whether i need to deploy a .bar file or a .bpmn or .bpmn20.xml
And in my eclipse activiti project there is pom.xml file, whether i need to use that file for deployment and i am not seeing the "create deployment artifacts" option in my eclipse.
Totally i am in confusion with all these files.
Please kindly help me.

Thanks in advance

mitpatoliya

POM.xml you need not to deploy.
Also I suggest you to go through this link to configure your eclipse to use Activiti workflow.
http://www.activiti.org/userguide/index.html

That's ok i have read the activiti userguide
and i have read this http://techblog.zabuchy.net/2012/creation-of-workflow-in-alfresco-using-activiti-step-by-step/ tutorial.
But when iam trying to deploy the workflow in that alfresco is not starting up.
Could you please tell me what are the files i need to deploy a workflow
As of my understanding i need to create a workflowModel file, workflow-context file spring configuration, and web-client-config-custom.xml.
But when iam adding all these files to extention folder alfresco not starting up

Please help in this regard

Thanks in advance

Also the processdefinition.xml file you need to deploy.

Only those 4 files are essential for workflow.

Also what is the error you are getting in the logs?

Hi

You can use the bootstrap method, export your bmpn20.xml file and put it under the extension folder(preferable create a workflow folder to place your workflows).
Then register your workflow in the context file and don't forget to configure the share-custom file.

ggoutham

Hi
Thanks for your reply
Whether i need to configure only share-custom file or both web-client-config(explorer) and share-custom file.
2. What about messages like .properties file.
If you dont mind can you provide any example that is used to configure workflow in both share and explorer,
so that i can understand clearly
Please help me,

Thanks in advance

If it is working in the enterprise version you can deploy the same way in the community as well.
Also you need to configure UI related to the one which you are going to use (explorer or Share) not necessary to configure for both.
And as you said you are not using any custom task you will not require model as well as you will not require any property file of any of these UI related files as well because those tasks are already configured in alfresco.

I am trying to deploy the workflow like this in the workflow console
i just copied my workflow to the location below and i have not configured to the share or explorer UI,
deploy activiti alfresco/WEB-INF/classes/alfresco/extension/workflows/eligo_review_approve.bpmn20.xml it is showing error like this
org.alfresco.error.AlfrescoRuntimeException: 01120027 Exception in Transaction.

This is my .bpmn20.xml

Can anybody provide an example for deploying the activiti workflow, so that i can understand easily.
My examples are not working correct.

Please help me in this regard

Thanks in advance

Is this your complete bpmn20.xml file? What if you create a simple process with a startEvent, userTask, and endEvent, can you deploy it?

Hi,
Are you able to upload your bpmn file using activiti-admin console ? For learning purpose, activiti-admin console is handy.
http://localhost:8080/alfresco/activiti-admin
Login with Admin account. Click Deployment menu–>Upload new–>Select your YOURWORKFLOW.bpmn20.xml file to upload.

If you're getting any error, please share bpmn20.xml file and error log files.

Hi Murali,
Thanks for your reply when i am trying to access the activiti-admin using this http://localhost:8080/alfresco/activiti-admin it is giving a 404 error. I am using community 4.2.c i have tried this bpmn20.xml file in enterprise edition it is working fine
Is activiti-admin works in community editions??
And why my workflow is not working in 4.2.c

Regards,
Goutham

Hi Mike,
Thanks for your reply. I have not tried with the simple one but this workflow is working fine with enterprise edition.
I will try with a simple one and deploy it on the community editiion

Hi Goutham,
Activiti-admin is one of the Enterprise Edition feature 😞

I am using alfresco Enterprise 30days trail pack(i.e alfresco-4.14).
Now i have designed the custom workflow using activiti designer plugin in My eclipse Indigo & juno.

Actually my problem is when i am deploying my custom workflow it is working fine but i am not getting customised form in my workflow.

whether i don't know my requirement is possible or not.

If Possible can you please share related documents or videos or urls.

Thanks in Advance of sharing.
