Getting process definitions using REST API

[lhwong]

Using the following code available at mswiderski/spring-jbpm-app · GitHub, I manage to the process definitions

Collection<ProcessDefinition> processDefinitions = runtimeDataService.getProcesses(new QueryContext(0, 100));

Example

Available process definitions

---

Nb	Name	Version
1	Evaluation	1

---

However, when using REST API as per droolsjbpm-integration/DeploymentsResourceImpl.java at 6.2.x · droolsjbpm/droolsjbpm-integration · GitHub

http://localhost/kie-wb/rest/deployment/processes

I got a empty list.

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

<process-definition-list/>

Any idea?

Hi,

Some details

I am using kie-wb-distribution-wars-6.2.0.Final-tomcat7. I manage to get task list http://localhost/kie-wb/rest/task/query.

And, when making call using the Java API and REST API, I am in the same sign in session.

kie-wb and that sample spring app are two independent applications. So they must either be configured to use same data source and then use deployment synchronizer (enabled by default in kie-wb) to move same deployments around. Otherwise they will have its own set of deployments independent of each other.

HTH

They are both configured to use same data source. Although I am unsure about deployment synchronizer. As far as I understand, no change has been made (enabled by default in kie-wb). Could you please give me a pointer on this?

By the way, the task list are synchronized among both of the applications. Both

//called from spring app

Collection<TaskSummary> tasks = runtimeDataService.getTasksAssignedAsPotentialOwner(userId, new QueryFilter(0, 100));

//called via Javascript

http://localhost:8080/kie-wb/rest/task/query?potentialOwner=krisv

return the same task list.

There is a bug in the REST call, see: [JBPM-4578] /rest/deployment/processes broken - JBoss Issue Tracker .  The problem is with the pagination.  The workaround is to use :

http://localhost/kie-wb/rest/deployment/processes?p=0&s=100 .

BTW, Are you making raw rest calls or are you using the kie-remote api.  I tried this:

    private void getProcessDefinitions() {

        KieBase kbase = ksession.getKieBase();

        System.out.println( "Getting the processes." );

        Collection<Process> processes = kbase.getProcesses();

        int count = 1;

        for ( Process p : processes ) {

            System.out.println("\nprocess: " + count++ );

            System.out.println( "  process: "  + p );

        }

    }

And got:  java.lang.UnsupportedOperationException: The KieSession.getKieBase(..) method is not supported on the Remote Client instance.

Is there an way to generate the REST call via the API?
