Activiti on Spring configuration issue with navigatorManager

macbarfuss

I try to get Activiti including Explorer (and Camel, doesn't matter here) running in a spring container.

The Activiti Engine is working. (At least, there is no error on startup) But I can't get the explorer running.

mvn camel:run dies with java.lang.reflect.InvocationTargetException

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'navigatorManager'
Caused by: java.lang.NullPointerException
   at org.activiti.explorer.navigation.TaskNavigator.<init>(TaskNavigator.java:51)
‍‍‍‍‍

I'm not quite sure if the beans-configuration is complete.

Everything is fine if I comment out following line from context definition:

<bean name="navigatorManager" class="org.activiti.explorer.navigation.NavigatorManager" />‍

I actually do have a

   <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
      <property name="processEngineConfiguration" ref="processEngineConfiguration" />
   </bean>
‍‍‍‍‍

Can anybody give me a hint what I forgot?

EDIT: added the info the problem is concerning the explorer.

Hi there!

I compared my configuration with the examlpe configuration attached to "Activiti In Action" (book-camel) and corrected some entries.

Now it runs.

Maybe you can share what you did wrong, can be interesting for other uses as well…

Yes, you're right.

When I tried to get everything up I added the necessary beans and tried to start with mvn camel:run.

I first had errors here:

<br> <bean id="repositoryService" factory-bean="processEngine"<br>&nbsp; factory-method="getRepositoryService" /><br> <bean id="runtimeService" factory-bean="processEngine"<br>&nbsp; factory-method="getRuntimeService" /><br> <bean id="taskService" factory-bean="processEngine"<br>&nbsp; factory-method="getTaskService" /><br> <bean id="historyService" factory-bean="processEngine"<br>&nbsp; factory-method="getHistoryService" /><br> <bean id="managementService" factory-bean="processEngine"<br>&nbsp; factory-method="getManagementService" /><br>

I tried to figure out what was wrong and found similar bean configurations on the web with processEngingeConfiguration as factory-bean, like:

<br> <bean id="repositoryService" factory-bean="processEngingeConfiguration"<br>&nbsp; factory-method="getRepositoryService" /><br> <bean id="runtimeService" factory-bean="processEngingeConfiguration"<br>&nbsp; factory-method="getRuntimeService" /><br> <bean id="taskService" factory-bean="processEngingeConfiguration"<br>&nbsp; factory-method="getTaskService" /><br> <bean id="historyService" factory-bean="processEngingeConfiguration"<br>&nbsp; factory-method="getHistoryService" /><br> <bean id="managementService" factory-bean="processEngingeConfiguration"<br>&nbsp; factory-method="getManagementService" /><br>

Then this seamed to work until I got the error when I started this thread. I had to change things back as shown in the first code block.

But I'm sorry, I have no idea why this did not work and works now. Maybe I changed a dependency from maven but can't remeber.
