Hi,i have a simple demo process <?xml version="1.0" encoding="UTF-8"?><definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="h

have you passed the variable to activiti ? maybe you can also include your example.java

No actually i haven't passed it. My code is basically from the 10 minute tutorial. I find it very hard to make the first steps into the world of activiti to be honest, thus i did not know that i had to pass the variable to activiti nor how i do this. Any example code would be helpful.

<code>

public class activitiExample{

public static void main(String[] args) {

boolean requestApproved = true;

// Create process engine
     ProcessEngine processEngine = ProcessEngineConfiguration
       .createStandaloneProcessEngineConfiguration()
       .buildProcessEngine();

     // Get activiti services
     RepositoryService repositoryService = processEngine.getRepositoryService();
     RuntimeService runtimeService = processEngine.getRuntimeService();
     TaskService taskService = processEngine.getTaskService();
     FormService formService = processEngine.getFormService();

     // Deployment of process definitions
     repositoryService.createDeployment()
       .addClasspathResource("diagrams/FinancialReportProcess.bpmn20.xml")
       .deploy();

     // Start process instance
     String procId = runtimeService.startProcessInstanceByKey("financialReport").getId();
     String procDefId = runtimeService.startProcessInstanceByKey("financialReport").getProcessDefinitionId();

     // Get first task

     List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("accountancy").list();
     for (Task task : tasks) {
       System.out.println("Following task is available for accountancy group: " + task.getName());
       // claim it
       taskService.claim(task.getId(), "fozzie");

     }

     // Verify Fozzie can now retrieve the task
     tasks = taskService.createTaskQuery().taskAssignee("fozzie").list();
     for (Task task : tasks) {
       System.out.println("Task for fozzie: " + task.getName());

       // Complete the task
       taskService.complete(task.getId());

     }

     System.out.println("Number of tasks for fozzie: "
             + taskService.createTaskQuery().taskAssignee("fozzie").count());

     // Retrieve and claim the second task
     tasks = taskService.createTaskQuery().taskCandidateGroup("management").list();
     for (Task task : tasks) {
       System.out.println("Following task is available for accountancy group: " + task.getName());
       taskService.claim(task.getId(), "kermit");

     }

     // Completing the second task ends the process
     for (Task task : tasks) {
       taskService.complete(task.getId());
     }

   }

}

But the exception is pretty clear, no?

"Unknown property used in expression: ${requestApproved == "true"}"

It can't find the property you used to go either left or right in the process.

@jbarrez: Indeed the error message is very clear. My problem is that i don't have a clue how to parse the variable requestApproved from the very first line of my java code into the activiti process lifecycle…

runtimeService.startProcessInstanceByKey("financialReport") needs to have the variables … needs to be runtimeService.startProcessInstanceByKey("financialReport", variables) where variables is a Map<String, Object>
