Hi All,
I''m trying to create sample workflow dynamic participant chooser by following doc [1]. I'm getting error message as shown in the attached image. I've also verified bundles and all are in active state (http://localhost:4502/system/console/bundles). It would be great if someone can help me on this.
My Java class:
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.Constants;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.day.cq.workflow.WorkflowException;
import com.day.cq.workflow.WorkflowSession;
import com.day.cq.workflow.exec.ParticipantStepChooser;
import com.day.cq.workflow.exec.WorkItem;
import com.day.cq.workflow.metadata.MetaDataMap;
@Component
@Service
@Properties({
@Property(name = Constants.SERVICE_DESCRIPTION, value = "An example implementation of a dynamic participant chooser."),
@Property(name = ParticipantStepChooser.SERVICE_PROPERTY_LABEL, value = "Workflow Initiator Participant Chooser") })
public class DynamicParticipant implements ParticipantStepChooser {
private Logger logger = LoggerFactory.getLogger(this.getClass());
public String getParticipant(WorkItem arg0, WorkflowSession arg1,
MetaDataMap arg2) throws WorkflowException {
String initiator = arg0.getWorkflow().getInitiator();
logger.info("Assigning Dynamic Participant Step work item to {}",initiator);
return initiator;
}
}
Error in the log:

Note: I'm using AEM 6.1 and Java 7. I've not installed any hotfixes.

Hi Siva,
Were you able to fix this issue? Would you be able to tell us the root cause and the fix? I am getting the same issue with the Workflows.
