How to implement Auto task in Alfresco for Activiti

[kavilash23]

Hi guys,

I am using activiti to built a workflow and I need to create an automated task so as to access certain custom type model properties in Alfresco from the workflow.  The task has to carry out a number of functions such as transforming a document and applying an md5 hash to the content.  As such we would like to implement the task using a JAVA bean.   And from the alfresco/activiti documentation, It is unclear how to do this.  The two options seem to be:

Extend the BaseJavaDelegate  class
Or
Implement the ActivityBehavior interface.

So can anyone shed some light on how to implement this for an Alfresco Activiti workflow.

Regards,

Kavi

Hi,

You could do it creating a service task:

In the workflow definition define the service task:

<serviceTask id="socialPublish" name="My task" activiti:delegateExpression="${myTask}">   <documentation>My task</documentation></serviceTask>‍‍‍‍‍

In the spring bean define the myTask bean as follows and add it to the activitiBeanRegistry:

<util:map id="activitiBeanRegistry" map-class="java.util.HashMap">        <entry key="services" value-ref="ServiceRegistry"/>        <entry key="myTask" value-ref="myTask"/>    </util:map>         <bean id="myTask" class="org.alfresco.poc.wf.delegates.MyTaskDelegate">      <property name="…">         <ref bean="…" />      </property>   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍

The MyTaskDelegate has to extend the JavaDelegate class
