Set process instance variables and get task input

[vinhd...@ved.com.vn]

I've been research jBPM for the past month, but i still struggle with some of its APIs

1. First one is set process instance variables.

- I use /rest/execute in attempt to use SetProcessInstanceVariablesCommand but with no luck

- Here is my request

http://test2.ved.com.vn:8080/jbpm-console/rest/execute 

Request body:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<command-request>
  <deployment-id>ved:PrinterManagement:1.0</deployment-id>
  <set-process-instance-variables processInstanceId="5">

    <parameter>
      <item key="NVRSD_UID">
        <value xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">11</value>
      </item>
    </parameter>
  </set-process-instance-variables>
</command-request>

The request response with status 200, and data:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<command-response>
    <deployment-id>ved:PrinterManagement:1.0</deployment-id>
</command-response>

Result: var NVRSD_UID not set in process instance

2. Second one is way get task input

- I can't figure out the way to get input of some task. E.g: task A want id as String, imported_date as Date

- I've tried using showTaskForm, but that API is such a pain, i can't embedded in my client application (because of cross domain), 

- and jbpm-forms-rest-integration.js also didn't work because it make unauthorized request (401)

Please someone help me with these 2 problems.

I'm installed jBPM 6.5.0 Final on Ubuntu 14.04

Edit:

Request body is:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<command-request>
  <deployment-id>ved:PrinterManagement:1.0</deployment-id>
  <set-process-instance-variables processInstanceId="5">

    <variables>

      <item key="NVRSD_UID">
        <value xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">11</value>
      </item>

    </variables>
  </set-process-instance-variables>
</command-request>

any help please?

I'd recommend you to use KIE Server instead that has easier to consumer API and provides simple way of setting process variables. When it comes to second question it does come with definition service exposed as well so you can get task information over REST as well.

Once deployed KIE Server all available endpoints you can find at http://localhost:8080/kie-server/docs

Hi Maciej,

Thanks for your response, i've looked over the kie server api,

1. I created a container (name: evalserver to manage stuffs on Evaluation)

2. I've sucessfully called http://localhost:8080/kie-server/services/rest/server/containers/evalserver/processes/instances/4 to get process instance information

3. Then i call http://localhost:8080/kie-server/services/rest/server/containers/evalserver/processes/instances/4/variable/reason tried to get variable reason value, but the request response with 'Could not find container "evalserver"'

Am i missing something?

I suspect that the problem is due to the fact that you created the instance in the business central and now you are going to call the kie server API.

If you use RedHat BPMS v6.4 or jBPM v6.5, you can do that but your container name should be the same of deployment descriptor of your kjar. e.g. org.test:test:1.0-SNAPSHOT

Hi, i have the same issue.

Im my case i had this message in logs: "[org.kie.remote.services.rest.ExecuteResourceImpl] (default task-6) Commands request object with no commands sent!"

Then i looked to source code:  http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/releases/org.kie.remote/kie-remote-services/6.3.0.Beta2/org/kie/remote/services/jaxb/JaxbCommandsRequest.java#130

Maybe, you should replace"set-process-instance-variables" to "set-process-instance-vars".

For example:

<command-request>

  <deployment-id>org.guvnor:guvnor-asset-mgmt-project:6.5.0.Final</deployment-id>

  <set-process-instance-vars processInstanceId="572">

    <variables>

      <item key="test">

        <value xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema"

               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">test</value>

      </item>

    </variables>

  </set-process-instance-vars>

</command-request>
