Hi Sergio,
Try using developerHelperService. I have used it to get the current reference to see who is logged in. This might be of help.
Kind Regards,Nguni

Dear All,I've been trying to obtain the user from the current session (if there is a user logged in), or from somewhere else using the API or a web service, but I've been having difficulties finding an example that works. 

All I need from the user is his/her type (table sakai_user, field type). 

This is what I have in my web service:
import org.sakaiproject.tool.api.Session;import org.sakaiproject.tool.api.SessionManager;
import org.sakaiproject.user.api.User;import org.sakaiproject.user.api.UserDirectoryService;
	private UserDirectoryService userDirectoryService;
	......		userDirectoryService = (UserDirectoryService) ComponentManager.get(UserDirectoryService.class.getName());
........		Session session  = sessionManager.getCurrentSession();		
		// check if session is active		if (session == null) {			System.out.println("*** Current session is null.");
			LOG.warn("WS RemoteReportCourses.establishSession(): Session " + sessionid + " is not active.");				throw new AxisFault("WS RemoteReportCourses.establishSession(): Session " + sessionid + " is not active");
		} else {			System.out.println("*** Session: " + session);			System.out.println("*** session id: " + session.getId());
			System.out.println("*** user id: " + session.getUserId());			User currentUser = null;			try {
				currentUser = userDirectoryService.getUser(session.getUserId());			} catch (UserNotDefinedException unde) {
				System.out.println("*** An error occurred: " + unde.getMessage());				unde.printStackTrace();			}
			if (currentUser == null) {				System.out.println("*** Current user is null.");			} else {
				System.out.println("*** User: " + currentUser);				System.out.println("*** User.getId(): " + currentUser.getId());
				System.out.println("*** User.getEid(): " + currentUser.getEid());				System.out.println("*** User.getType(): " + currentUser.getType());
			}			}
According to this page:https://confluence.sakaiproject.org/display/BOOT/Using+the+UserDirectoryService
it should work, but this is all I get no matter if I'm logged into Sakai or not (I'm doing local development/testing):
2014-07-17 14:23:21,470  INFO http-bio-8080-exec-6 org.sakaiproject.util.RemoteHostFilter - Access granted (.+): 127.0.0.1/127.0.0.1
*** Session: org.sakaiproject.tool.impl.MySession at 5414ede*** session id: 8bd4e3bb-0733-47f6-b383-6e855435fa5c*** user id: null*** An error occurred: null*** Current user is null.


There's another option to try but looks a little bit more complicated since it uses Spring framework injection and I don't really know how to configure it for a web service.

Can anybody help me with this issue? Or with any web service that can give me the information that I want?Please note that I don't want the user give me his/her login/password again in a customized form, I want to take it from the current session. My Sakai version: 2.9.1

Thank you in advance. I really appreciate any help.
