Hi,

IMO this should be possible.

To answer the question, we need some information about your project and his structure to be able to troubleshoot the error.

Hi,

Thank you for your quick response. I want to remake the same model in this activiti project in an AMP project without Junit of course.

Hi,

In an AMP ? you mean for Alfresco ?

In order to get rid of that ActivitiException, you will need to create a deployment containing the drool rule.

In your zip file the JUnit test do it with the following line :

String deploymentID = repositoryService.createDeployment().name("BusinessRuleLoanProcess.bar")
      .addZipInputStream(inputStream).deploy().getId();

But there is nothing that do the same in your non-test code.

Yes, i mean Alfresco.

How to add the drool rule to the process (we have not activiti.cfg.xml in Alfresco).

Activiti embeded in Alfresco work the same way as the standalone one.

But I think you should take a look at the version embedded with your Alfresco.

You can grab the version in the jar name located in alfresco/WEB-INF/lib folder.

So you have to generate the bar file using your activiti project (the zip you attach to the case) and put that file in your AMP project.

Then you could deploy it to the engine using the code in my last comment. You will need to call that piece of code at startup.

You could look at the alfresco SDK sample : alfresco-sdk-samples/samples/alfresco-simple-module/repo at master · Alfresco/alfresco-sdk-samples · GitHub

Hi Seif _ ,

Yes it is possible to create business rule task with the Alfresco Activiti. However, it is recommended to use the Decision Task with Decision Table with Alfresco Activiti. Have a look at the documentation about Business Rule Task here Alfresco Activiti. So, in order to implement process rules, you should use the Business Decision Table as documented here Alfresco Activiti.

It should work if you follow the instruction carefully.

I attached a recording of my successful execution of a sample process with a business rule table.

About your error message

org.activiti.engine.ActivitiException: deployment 23701 doesn't contain any rules.

Have you run the process definition validation utility to see if your process definition is correct? Looks like you're missing an implementation of the rule task. How did you define your rule task in your process?

Hope this helps,

Thanks

Thong Huynh

Hi Seif _‌,

Alfresco got an activiti.cfg.xml equivalent in it's core (community-edition/activiti-context.xml at 2c1eff9953d3105e738f7b06ba9ba8a079ca4c24 · Alfresco/community-edition · GitHub )

I checked the code available on github (GitHub - Alfresco/community-edition: Mirror of Alfresco Community Edition (see https://wiki.alfresco.com/wiki/GitHub) ) and didn't find anything related to the RulesDeployer.

So I'm not sure that activiti feature is available in Alfresco.

Maybe Francesco Corti‌ got some informations about that.

Hi Yann Coulon‌, Hi Seif _‌,

The answer is that there is no business rule component for Alfresco Workflow.

I hope this helps.
