how can I get the files detail in the bpm_package

[forrest43]

I have defined a process, which including a service task node, and set the activiti:expression of the service task as followed,

<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">

      <serviceTask id="servicetask1" name="Service Task" activiti:expression="#{generateTemplateBean.generateTemplate(execution)}"></serviceTask>
      <sequenceFlow id="flow8" name="" sourceRef="alfrescoUsertask1" targetRef="endevent2"></sequenceFlow>

      <sequenceFlow id="flow14" name="" sourceRef="servicetask1" targetRef="alfrescoUsertask1"></sequenceFlow>
    </subProcess>
    <startEvent id="alfrescoStartevent1" name="Alfresco start" activiti:formKey="ewf:collectStart"></startEvent>
    <userTask id="review_task2" name="review_task" activiti:assignee="${initiator.properties.userName}" activiti:formKey="ewf:viewTask"></userTask>

    <sequenceFlow id="flow11" name="" sourceRef="collectDoc" targetRef="review_task2"></sequenceFlow>

  </process>
</definitions>

the details of the generateTemplatedBean:

public class GenerateTemplateBean{
public void generateTemplate(DelegateExecution execution){
      ActivitiScriptNode bpmPackage = (ActivitiScriptNode)execution.getVariables().get("bpm_package");
   }
}
‍‍‍‍‍‍‍

it's supposed that I can get the varible via DelegateExcution, but all the varible's type is ActivitiScriptNode, how can I get the files in the bpm_package, like path, file type, the content of the file.

Hi,

You can ge the Documents in Workflow by this Code

ActivitiScriptNode scriptNode = (ActivitiScriptNode)executionEntity.getVariable(WorkflowNotificationUtils.PROP_PACKAGE);
NodeRef packagenode = scriptNode.getNodeRef();
NodeRef docRef= serviceRegistry.getNodeService().getChildAssocs(packagenode).get(0).getChildRef();
‍‍‍‍‍

Thanks & Regards

Ok, it works, thank you so much!

[testuser]

Could you please explain how to get a document name from the docRef, do you have an example? that would be great, thanks!

[dmralfing]

NodeService nodeService=serviceRegistry.getNodeService ();
String nodeName=nodeService.getProperty (docRef, ContentModel.PROP_NAME);

Thanks!

Hi,

could you please explain how to get serviceRegistry object?
I have used "ApplicationContextHelper.getApplicationContext()" and ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml")
but getting Exception:

What do you want to do using ApplicationContextHelper,do you want to do unit test? if yes, you shoud copy alfresco-global.properties to your classpath and set your database connection info there.
