How to get process instance variables through jBPM Java Remote API

[jizuzqui]

Hi all,

is is possible to retrieve values of process instance variables through jBPM Java Remote API (kie-remote-client 6.2)?

Thanks in advance.

Jamie,

Use the below code to retrieve the process instance variables as a Map<String,Object>. I have tested it, works fine!

ProcessInstance pi = ksession.getProcessInstance(processInstance.getId());

  RuleFlowProcessInstance rfpi = (RuleFlowProcessInstance)pi;

  Map<String,Object> variable = rfpi.getVariables();

  System.out.println(variable);

Muthu,

I don't find any RuleFlowProcessInstance class definition in kie-remote-client...

Try these 4 dependencies

<dependency>

  <groupId>org.kie</groupId>

  <artifactId>kie-api</artifactId>

  <version>6.3.0.Final</version>

  </dependency>

  <dependency>

  <groupId>org.kie</groupId>

  <artifactId>kie-internal</artifactId>

  <version>6.3.0.Final</version>

  </dependency>

  <dependency>

  <groupId>org.jbpm</groupId>

  <artifactId>jbpm-flow</artifactId>

  <version>6.3.0.Final</version>

  </dependency>

  <dependency>

  <groupId>org.jbpm</groupId>

  <artifactId>jbpm-test</artifactId>

  <version>6.3.0.Final</version>

  </dependency>

Code for the same

package com.sample;

import java.io.IOException;

import java.util.HashMap;

import java.util.Map;

import org.jbpm.ruleflow.instance.RuleFlowProcessInstance;

import org.jbpm.test.JbpmJUnitBaseTestCase;

import org.junit.Test;

import org.kie.api.runtime.KieSession;

import org.kie.api.runtime.manager.RuntimeEngine;

import org.kie.api.runtime.manager.RuntimeManager;

import org.kie.api.runtime.process.ProcessInstance;

/**

* This is a sample file to test a process.

*/

public class ProcessTest extends JbpmJUnitBaseTestCase {

  @Test

  public void testProcess() throws IOException {

  RuntimeManager manager = createRuntimeManager("com/sample/sample.bpmn");

  RuntimeEngine engine = getRuntimeEngine(null);

  KieSession ksession = engine.getKieSession();

  Map<String,Object> map = new HashMap<String, Object>();

  map.put("input", "VALUE");

  ProcessInstance processInstance = ksession.startProcess("com.sample.bpmn.hello",map);

  System.out.println(processInstance.getId());

  ProcessInstance pi = ksession.getProcessInstance(processInstance.getId());

  RuleFlowProcessInstance rfpi = (RuleFlowProcessInstance)pi;

  Map<String,Object> variable = rfpi.getVariables();

  System.out.println(variable);

  }

}

You can use the same dependencies along with remote client.
