Get the current user Liferay using a simple Java code

I'm working with : Liferay 6.0.6 with JBoss 5.1 and Struts2.

My question is, how to get the current user in Liferay once logged in, using a Java code.

This is an other possible way to do it :

private LiferayFacesContext liferayFacesContext = LiferayFacesContext.getInstance();
User currentUser=liferayFacesContext.getUser()

Liferay provides Util class

com.liferay.portal.util.PortalUtil

This class contains all utility methods to get the frequently used attributes.

Try using PortalUtil.getUser(PortletRequest portletRequest) method to avoid creating new objects and references.

In your doView/processAction method do following

User user = (User) request.getAttribute(WebKeys.USER);

or use the ThemeDisplay object. It contains another information like companyId, groupId, ...

ThemeDisplay td  =(ThemeDisplay)request.getAttribute(WebKeys.THEME_DISPLAY);
User user = td.getUser();

Classes ThemeDisplay, User nad WebKeys are part of portal-service.jar.

If you need just some id to identify current user you can also use 

String userId = request.getRemoteUser();

This solution is not Liferay specific and should be portable among jsr-286 portals.
