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

I am running demo demo.start and the unit tests in the examples work.I took the pom.xml from activiti-engine.examples and repurposed it for this example.
package com.demo;
import java.util.List;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.DeploymentQuery;
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("com/demo/demo-flow.bpmn20.xml").deploy();
/* Start the process by id. */
processEngine.getRuntimeService().startProcessInstanceById("financialReport");
//fails with the above call with the above exception
}
}
The above uses this demo-flow.bpmn20.xml:

I have written some other code that works in the same project as follows:
package com.demo;
import org.activiti.engine.impl.pvm.ProcessDefinitionBuilder;
import org.activiti.engine.impl.pvm.PvmActivity;
import org.activiti.engine.impl.pvm.PvmExecution;
import org.activiti.engine.impl.pvm.PvmProcessDefinition;
import org.activiti.engine.impl.pvm.PvmProcessInstance;
import org.activiti.engine.impl.pvm.delegate.ActivityExecution;
import org.activiti.engine.impl.pvm.delegate.SignallableActivityBehavior;
public class DemoUsingFluentAPI {
static PvmProcessDefinition processDefinition = new ProcessDefinitionBuilder()
.createActivity("find bacon")
.initial()
.behavior(new MyActivityBehavior())
.transition("find eggs")
.endActivity()
.createActivity("find eggs")
.behavior(new MyActivityBehavior2())
.transition("find orange juice")
.endActivity()
.createActivity("find orange juice")
.behavior(new MyActivityBehavior3())
.endActivity()
.buildProcessDefinition();
public static class MyActivityBehavior implements SignallableActivityBehavior {
public void execute(ActivityExecution execution) throws Exception {
System.out.println("Here ");
execution.take(execution.getActivity().getOutgoingTransitions().get(0));
}
public void signal(ActivityExecution arg0, String arg1, Object arg2)
throws Exception {
System.out.println("Here signal");
}
}
public static class MyActivityBehavior2 implements SignallableActivityBehavior {
public void execute(ActivityExecution execution) throws Exception {
System.out.println("Here 2");
execution.take(execution.getActivity().getOutgoingTransitions().get(0));
}
public void signal(ActivityExecution arg0, String arg1, Object arg2)
throws Exception {
System.out.println("Here signal 2");
}
}
public static class MyActivityBehavior3 implements SignallableActivityBehavior {
public void execute(ActivityExecution execution) throws Exception {
System.out.println("Here 3");
execution.end();
}
public void signal(ActivityExecution arg0, String arg1, Object arg2)
throws Exception {
System.out.println("Here signal 3");
}
}
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();
//
// RuntimeService runtimeService = processEngine.getRuntimeService();
PvmProcessInstance processInstance = processDefinition.createProcessInstance();
processInstance.start();
PvmActivity activity = processDefinition.findActivity("find bacon");
activity.findOutgoingTransition("find eggs");
PvmExecution activityInstance = processInstance.findExecution("find bacon");
assert activityInstance!=null : "Not Null";
}
}
Can I get some ideas on how to debug this?
