Hi,

the problem is:


Exception in thread "main" org.activiti.engine.ActivitiIllegalArgumentException: unknown type 'user' approver

Your process engine configuration


ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()

differs from process engine configuration used by activiti explorer. Process definition (form type) refers to the undefined type (it is not configured in the process engine configuration)


  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
   <property name="dataSource" ref="dataSource" />
   <property name="transactionManager" ref="transactionManager" />
   <property name="databaseSchemaUpdate" value="true" />
   <property name="jobExecutorActivate" value="true" />
    <property name="customFormTypes">
      <list>
        <bean class="org.activiti.explorer.form.UserFormType"/>
        <bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/> 
        <bean class="org.activiti.explorer.form.MonthFormType"/>   
      </list>
    </property>
  </bean>

Thanks For your Quick Reply !

Could you Show Me The Right Method to Create ProcessEngine, Please?

I tried

<java> ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine() </java>

but it throws null pointer Exception !!

Hi Mahmoud,

Your jUnit test can extend org.activiti.engine.impl.test.ResourceActivitiTestCase. In the constructor you can point to the resource (your own activiti context -> activiti-standalone-context.xml) to configure the engine.
