10 minute guide example, deployment fails

I am trying to get the 10 minute guide example to work in a standalone application.I am getting the following errorEVERE: Error while closing command contextorg.activiti.engine.ActivitiException: no deployed process definition found with id 'financialReport' at org.activiti.engine.impl.db.DbRepo

I went through the tutorial for the eclipse plugin and it worked.
Well, the unit test worked in the unit test only.


package org.activiti.designer.test;



import java.util.HashMap;
import java.util.Map;

import org.activiti.engine.RuntimeService;
import org.activiti.engine.test.Deployment;
import org.activiti.engine.test.ActivitiRule;
import org.junit.Rule;
import org.junit.Test;

public class ProcessTestHelloworld {

 @Rule
 public ActivitiRule activitiRule = new ActivitiRule();

 @Test
 @Deployment(resources="diagrams/my_bpmn2_diagram.activiti.bpmn20.xml")
 public void startProcess() {
  RuntimeService runtimeService = activitiRule.getRuntimeService();
  Map<String, Object> variableMap = new HashMap<String, Object>();
  variableMap.put("name", "Activiti");
  variableMap.put("color", "BLUE");
  runtimeService.startProcessInstanceByKey("helloworld", variableMap);
 }
}

However, I don't know how to run it standalone.

I tried writing a main method that loads the same process.


package com.demo;

import java.util.List;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.task.Task;

public class Demo {
 
 public static void main (String [] args) {
  ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
     .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
     .setJdbcUrl("jdbc:h2:mem:my-own-db;DB_CLOSE_DELAY=1000")
     .setDatabaseSchemaUpdate("create-drop")
     .setJobExecutorActivate(true)
     .buildProcessEngine();
  
  
  /* Deploy the xml file. */
  processEngine.getRepositoryService()
  .createDeployment().addClasspathResource("diagrams/my_bpmn2_diagram.activiti.bpmn20.xml").deploy();
  
  /* Start the process by id. */
  processEngine.getRuntimeService().startProcessInstanceById("helloworld");
    
  List<Task> tasks = processEngine.getTaskService()
    .createTaskQuery().taskCandidateUser("fozzie").list();
  
  System.out.println("Got some tasks " + tasks);
  for (Task task : tasks) {
   System.out.println(task.getId());
  }
 }


}

I get the same exception I was getting before (well similar).

I want just a simple standalone example (that is not a unit test) that works.

BTW I did explore and try a few things with the unit test so I am not completely stuck.
Also the screenshots and generated code for the tutorial do not match the current plugin.

10 minute guide missing pieces.
Working tutorial with old screenshots.

Hi,

You should use the startProcessInstanceByKey('financialProcess') instead of startProcessInstanceById(''), this will fix your problem.

Activiti is an open-source project and has a large community of contributors. The Designer is completely contributed by a team in Holland, which do this after (!) their normal day-job, so they may have missed the userguide-update this time (we do monthly release, and designer functionality has grown a lot this month).

I'm not sure the best way to get help from us/our community is to tweet how #activiti #fails though…

I understand your criticism, the userguide must reflect the current state of things.

I've created following JIRA issues and planned them on release 5.3: http://jira.codehaus.org/browse/ACT-601 and http://jira.codehaus.org/browse/ACT-600

frederikheremans Thanks for your help that works well.

In the XML file, the attribute is called "id", and you have two methods with nearly identical names.

It is a bit confusing and code completion filled in the blanks. I did not even notice that they were different.

I thought I was cutting/pasting them out of the docs.

In any regard, it works now… thanks.

Regarding #fail, I was referring to my effort to get the 10 minute example to work. I will continue to tweet unabated.

It is clear to me that the failure was on my part for calling the wrong method.

Thanks again for your help.

Rick,

It's indeed a bit confusing that the process-definition "id" in the xml (bpmn 2.0 style), is actually the process key in activiti-terms.
You can tweet unbated, be my guest Keep on spreading the #activiti word!
