Adobe CQ : Develop custom workflow for DAM

[askdctm]

Hi All,

I am new to CQ, just started few weeks back.

I have to create a workflow wherein asset[say single/multiple .jpeg image] in one of the folder in DAM has to be moved to another folder[source and destination folders for now are say some dedicated folders], to get started with.

I have created a service [.java file with the basic framework of implementing interface,execute() method] and in the workflow console[ for a new workflow in the process step], I am able to tag my workflow to the service I have created.

However, I am struggling to write the logic here.

If someone could guide me here, to get started with . It would be really helpful.

Regards,

I'm not sure what you mean by:

Have you added the Process Step to your workflow model?

Hi Scott,

Yes, I have added a process step.

"I have created a service [.java file with the basic framework of implementing interface,execute() method] and in the workflow console[ for a new workflow in the process step]"

In the process step, my custom "Migrationnn Workflow" is appearing. However I am not able to generate a logic/code as to how, it needs to be done.

The annotations used in my java class file are as below:

@Component
@Service
@Properties(value = {
        @Property(name="service.description", value="Migrationnn Workflow"),
        @Property(name="service.vendor", value="xxxxxxxxx"),
        @Property(name="process.label", value="Migrationnn Workflow") })

I guess the workflow would be started using the asset as the payload. You can get the JCR path of the  payload (as shown in the code example here: https://dev.day.com/docs/en/cq/current/workflows/wf-extending.html#Developing%20Process%20Step%20Imp...). That example also shows how to get the JCR session object, and you can then use the Session.move method to move it (http://www.day.com/maven/jsr170/javadocs/jcr-2.0/javax/jcr/Session.html).

Hi Scott,

Thank you for your reply. 

Just saw your latest reply.

However, what I tried is as below[not working]

@Component
@Service
@Properties(value = {
        @Property(name="service.description", value="Migrationnn Workflow"),
        @Property(name="service.vendor", value="xxxxxxx"),
        @Property(name="process.label", value="Migrationnn Workflow") })

public class workflow implements WorkflowProcess
{
    @Reference
    private ResourceResolverFactory resolverFactory;
    @Reference
    private SlingRepository repository;
    private Session session;
    private static final Logger log = LoggerFactory.getLogger(workflow.class);
    
    
    @Activate
    public void activate() throws Exception{
        
        session=repository.loginAdministrative(null);
        
    }
    
    @Deactivate
    public void deactivate() throws Exception{
        
        
        session.logout();
    }
    public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaData) throws WorkflowException
    {
        //WorkflowData workflowData = workItem.getWorkflowData();
        // System.out.println("workflow data is " +workflowdata);
        
        try{
         
        String source = "/content/dam/dropfolder/drop";
        String dest   = "/content/dam/Destination/dest";

       // damPath = workflowData.getPayload().toString();
        //workflowSession.getSession().move(source, dest);
        //workflowSession.getSession().save();
        /*    
        Repository repository = JcrUtils.getRepository("http://localhost:4503/crx/server");
        
        //Create a Session
        javax.jcr.Session Session = repository.login( new SimpleCredentials("admin", "admin".toCharArray())); 
      

ResourceResolver resourceResolver = resourceResolverFactory.getAdministrativeResourceResolver(null);
Session userSession = resourceResolver.adaptTo(Session.class);*/
session.move(source,dest);
        
        
            
        }
        catch(Exception ex)
        {
            log.error("workflow error"+ex.getMessage());

            ex.printStackTrace();
        }
        finally 
        {
            //workflowSession.complete(workItem, (Route) routes.get(0));

            log.info(" workflow complete");

        }
    }

}

[Scott_Brodersen · Accepted solution]

To get the session object, a much easier way is: the execute method is passed the workflowSession object, so you can adapt it to the JCR Session object:

Session jcrSession = session.adaptTo(Session.class);

But beyond that, session.move requires that the parameters are paths to nodes. Is that the case for these?

String source = "/content/dam/dropfolder/drop";
String dest   = "/content/dam/Destination/dest";

Are you using a Launcher relationship to start the workflow?
