Yeah. But I am not able to run a simple process in eclipse. Attached are the POC components.

Do you see a stacktrace in the console? Are you sure the activiti.cfg.xml is on your classpath (make sure it's actually called activiti.cfg.xml, not activiti-cfg.xml unless you use another way of instantiating the engine).

There is no activiti.cfg.xml file in my classpath by default but I created a one. How to set it on classpath

Are you serious? Depends on your container and environment, but this is java 101. Don't think the activiti-forum is the best place to get answers on this kind of questions..

My question is whether the activiti.cfg.xml file will be creted once I create activiti project OR should I create the file separately, later add the same to classpath.

You need one activiti.cfg.xml file for each Activiti Process Engine instance you want to create.

Typically, each application has only need for one such engine and thus file. But you are free to have many more, eg activiti1.cfg.xml, activiti2.cfg.xml, etc.

Have activiti.cfg.xml in my classpath (path: src\test\resource) ut still the line (activitiRule.getRepositoryService():smileywink: returning null. activiti.cfg file has the entries as attached in my first comment.

May I know how can I upload my project to check something wrong I am doing here.

hello all

I had the same pb, I changed the JUnit version in my pom.xml from 4.11 to 4.11-beta-1 and it worked for me !!!
I am using activiti version 5.16.1

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11-beta-1</version>
    </dependency>

sorry, I made a mistake, it's not working either
I confirm that there is a pb with the following construct when we use the test unit with JUnit 4:
public class TaskServiceTest {

@Rule
public ActivitiRule activitiRule = new ActivitiRule("activiti.cfg-mem.xml");

private void startProcessInstance() {
RuntimeService runtimeService = activitiRule.getRuntimeService();
Map<String, Object> variableMap = new HashMap<String, Object>();
variableMap.put("isbn", "123456");
runtimeService.startProcessInstanceByKey("bookorder", variableMap);
}
…

my object activitiRule contains only null pointers, exept for configurationResource :

configurationResource = {java.lang.String@1133}"activiti.cfg-mem.xml"
deploymentId = null
processEngineConfiguration = null
processEngine = null
repositoryService = null
runtimeService = null
taskService = null
historyService = null
identityService = null
managementService = null
formService = null
mockSupport = null

what can we do to help you find why we encounter this problem ?

Could you wrap that whole project up in a zip file and post it here so we can have a look?

hello Joram,

did you have an oportunity to look at the source code I uploaded previously

it' s a very simple code example created in eclipse, the project has been created from the activiti eclipse plugin

the code is just doing this, and the result is that the activity rul object contains only null pointers inside it:

public class TestRule {
@Rule
public ActivitiRule activitiRule = new ActivitiRule("activiti.cfg-mem.xml");

@Test
@Deployment(resources={"bookorder.bpmn20.xml"})
public void ruleUsageExample() {
    RuntimeService runtimeService = activitiRule.getRuntimeService();
    Map<String, Object> variableMap = new HashMap<String, Object>();
    variableMap.put("isbn", "123456");
    runtimeService.startProcessInstanceByKey("bookorder", variableMap);

Hi,

change


  @Rule
  public ActivitiRule activitiRule = new ActivitiRule("activiti.cfg.xml");
  
  @Test
  @Deployment(resources={"diagrams/bookorder.bpmn20.xml"})
