Workflow Process is not in active state

Hi @robbierami,

Looks like your Workflow Process component is in an Unsatisfied state is because it's trying to inject a dependency (MailService) that doesn't exist or isn't available at runtime. Here’s how to fix it:

Your class probably looks like this:

@Component(service = WorkflowProcess.class,
           property = { "process.label=Send Email Workflow Step" })
public class EmailWorkflowProcess implements WorkflowProcess {

    @Reference
    private MailService mailService;

    // ...
}

And the OSGi console shows:

Unsatisfied Reference: com.day.cq.mailer.MailService

This means the MailService is not registered or available in your AEM instance.

1. Make sure you're using AEM 6.5 or have the right feature pack

The MailService (com.day.cq.mailer.MailService) is only available if:

• You're using AEM 6.5 with Communities or other related packages

• OR, the Day CQ Mailer bundle is installed and active.

Go to:
http://localhost:4502/system/console/bundles
Search for com.day.cq.mailer or CQ Mailer Service.

If the bundle is not there, the service will never resolve.

2. Use DefaultMailService from ACS AEM Commons (Optional Alternative)

If you only want to send emails and don’t specifically need MailService, you can:

• Use com.adobe.acs.commons.email.EmailService

• OR inject MessageGatewayService (Adobe recommends this)

Example using MessageGatewayService:

@Reference
private MessageGatewayService messageGatewayService;

3. Change the @Reference to Optional (If not always needed)

If MailService is optional (e.g., only needed in some conditions), mark the reference like this:

@Reference(cardinality = ReferenceCardinality.OPTIONAL)
private MailService mailService;

Or for OSGi R7 (AEM Cloud-compatible):

@Reference(policy = ReferencePolicy.DYNAMIC, cardinality = ReferenceCardinality.OPTIONAL)
private volatile MailService mailService;

That way your component can still activate.
