get User Task Form using REST api

[gurijala naresh]

Hi Experts,

I'm using JBPM6. My process have one varialble which is a Object. 

I pass this object to the process and some rules will be fired. After that object will be sent to User task where user will update some fields and submit. 

I'm able to test this from workbench. I'm wondering how we perofrm same using REST api.

-> How to get user task form in another application (using Angular )

-> How to get process varialble details using kie-server REST api.

Please help me on this.

Thanks,
Naresh

Hi Jagan,

Thanks for quick reply. 

I have one container 

GET ; http://localhost:8080/kie-server/services/rest/server/containers/lm/

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<response type="SUCCESS" msg="Info for container lm">

    <kie-container container-id="lm" status="STARTED">

        <release-id>

            <artifact-id>tbdemo</artifact-id>

            <group-id>lm</group-id>

            <version>1.1</version>

        </release-id>

        <resolved-release-id>

            <artifact-id>tbdemo</artifact-id>

            <group-id>lm</group-id>

            <version>1.1</version>

        </resolved-release-id>

        <scanner status="DISPOSED"/>

    </kie-container>

</response>

GET:

http://localhost:8080/kie-server/services/rest/server/containers/lm/processes/definitions/jbpmdemo/variables

No data found for this request.

But i have started one process from Workbench already.

Am i missing something. ?

Can we start process using REST call with Object as input. ( in my case UserDetails object which containes name, age, address etc.)

If you have some examples please send me. That would be great help.

Thanks, Naresh

check process in active or completed.

to start bpmn use this rest api :

http://localhost:8230/kie-server/services/rest/server/containers/containerid/processes/processid/instances 

method: post

username,password 

payload: 

{
  "applicant": {
    "com.qruize.demos.loandemo.Applicant": {
      "name": "jagan",
      "creditScore": 230
    }
  },
  "loan": {
    "com.qruize.demos.loandemo.Loan": {
      "amount": 2500,
      "duration": 24,
      "interestRate": 12,
      "approved": false
    }
  }
}

}

Getting response as :

Unable to create response: Can't unmarshall input string: { "lm.tbdemo.UserProfile" : { "name": "naresh", "goal": "car", "id": 25, "isFirstQuestion" : true, "previousQuestion" : null, "answer" : null, "nextAction" : null, "nextQuestion" : null } }

Hi Maciej,

I followed the article but was not able understand how we are getting input/output forms to complete user task. 

In my process Rules task output(which is custom Object) is input to the UserTask. We need to change that object in user task.

process will be like this .

Thanks,
Naresh

[jagan reddy]

  "id": 25,

  "isFirstQuestion" : true,

  "previousQuestion" : null,

  "answer" : null,

  "nextAction" : null,
