problem is still not resolved.

List<HistoryItem> histories = wfSession.getHistory(workItem.getWorkflow()); HistoryItem firstItem = histories.get(0); String currentParticipant= firstItem.getUserId(); As per your response, tried the same code, but its not giving current user. It's giving last user.

final List<HistoryItem> histories = wfSession.getHistory(workItem.getWorkflow()); final HistoryItem firstItem = histories.get(0); String lastParticipant= firstItem.getUserId();

workItem.getWorkflow().getInitiator();Gives the details of user who initiated the workflow, which is not my requirement.I need to get the detail of the user, who currently logged in and running a particular step(process step or dynamic participant step).

I  tried to get current user using session and authorizable. But none of them giving the current user who invokes the particular step.Is there any other way to get the current user details ?
