Reference to FileFolderService in jbpm Workflow Java Action

[netboy1977]

Hello all,

I want to create folders from Java action in an jbpm Workflow (Alfresco 3.4d). I am a bit confused how to do this in Java since the JS Code is quite simple and it seems to be far more difficult in Java.

How best to insert a reference to FileFolderService in a workflow Java action?

According to NodeRef cookbook you receive an instance to FileFolderService this way:

ServiceRegistry serviceRegistry = (ServiceRegistry) beanFactory.getBean(ServiceRegistry.SERVICE_REGISTRY);
      
       FileFolderService fileFolderService = serviceRegistry.getFileFolderService();
‍‍‍‍‍

However, I see no way to get the serviceRegistry since I am implementing org.jbpm.graph.def.ActionHandler which only provides org.jbpm.graph.exe.ExecutionContext.

This is my relvant action code in the process definiton:

    <event type="node-leave">
      <action class="org.example.FileFolderCreator"/>
   </event>   
‍‍‍‍‍

Questions:


1. Which interface to best implement to get a reference of ServiceRegistry?
2. Do I have to add/inject anything to my workflow action?
3. Is there another way to acquire this, i.e. use NodeService?

Thanks for your replies!

Hello,

for Java actions in jBPM workflows you should be extending the Alfresco-specific JBPMSpringActionHandler class which provides you with a initialiseHandler method that has a BeanFactory as a parameter. Then the example from the Cookbook will work just as in your example - the service reference obtained needs to be put into a member variable in order for the execute method to have access to it, but that is about all the extra wiring you need.
