Wow that's a lot of console output that isn't very useful.
I don't see anything wrong in your logic, but is the RepositoryService defined as a Spring bean somewhere?

Best regards,

thank you ! yes,I did it like spring example:


   <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/activity?autoReconnect=true" />
    <property name="username" value="activity" />
    <property name="password" value="activity" />
     <property name="defaultAutoCommit" value="false" />
  </bean>
  
  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
  </bean>
  
  <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
   <property name="dataSource" ref="dataSource"/>
      <property name="persistenceXmlLocation">
          <value>classpath:custom-persistence.xml</value>
      </property>
   <property name="jpaVendorAdapter">
    <bean class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter">
     <property name="databasePlatform" value="org.apache.openjpa.jdbc.sql.MySQLDictionary" />
    </bean>
   </property>
  </bean>
  
  <context:annotation-config />
  <tx:annotation-driven transaction-manager="transactionManager"/>
  
  <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="mailServerHost" value="localhost" />
    <property name="mailServerPort" value="5025" />
    <property name="jpaEntityManagerFactory" ref="entityManagerFactory" />
    <property name="jpaHandleTransaction" value="true" />
    <property name="jpaCloseEntityManager" value="true" />
    <property name="jobExecutorActivate" value="false" />
  </bean>
  
  <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
    <property name="processEngineConfiguration" ref="processEngineConfiguration" />
  </bean>
  
  <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
  …..
  <bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService" />

</beans>

use junit test it behavior very well,bat in springMVC's controller I use spring's autowired annotation ,
   @Autowired                                       // autowired annotation
   protected ProcessInstance processInstance;
   …..
   if(processInstance == null){
      logger.info("—-processInstance isn't established—–");
   }
I guess in here ,my controller's context changed ,and can't access Root Context.

finally, I checked the springMVC-servlet.xml and fund that
<context:annotation-config />
this line is forgot.
after appended this line ,the inject var repositoryService ,processEngine…all are available.
thank you trademak! and merry christmas for you !
—wish you happy from a chinese programer!

Hi, This is a very old post, but I am facing exactly same problem. I dont see which line you actually added that made it work.
