How can I get current portal user from javax.portlet.Portlet

[freesoul]

hi ,
i want to obtain the current user object from my prtlet based on struts2 portlet,but I can only get javax.portlet.PortletContext use

PortletActionContext.getPortletContext()

in referenceGuide of Jboss Portal, it says

The org.jboss.portal.api.PortalRuntimeContext gives access to state or operations associated at runtime with the current user of the portal. The String getUserId() retrieve the user id and can return null if no user is associated with the context. It also gives access to the PortalSession instance associated with the current user. Finally it gives access to the NavigationalStateContext associated with the current user.

but how can i associate javax.portlet.PortletContext with org.jboss.portal.api.PortalRuntimeContext??

thank you!!

Yesterday I can't understand jboss portlet container very well, so I didn'i konw the relationship between javax.portlet.ActionRequest and org.jboss.portlet.JBossActionRequest, but now I get it.

public class org.jboss.portlet.JBossActionRequest extends org.jboss.portal.portlet.impl.jsr168.api.ActionRequestImpl {
}

and implements javax.portlet.ActionRequest interface.

So we can get current user in struts2 like that:

((org.jboss.portlet.JBossActionRequest) PortletActionContext
 .getActionRequest()).getUser();

I need to get the current user of the system to display a jsp page in the portlet. According to docs ,i tried to implement the PortalRuntimeContext interface , but no success.....

You seem to be successful in it.however i am not using the struts framework. is it possible to retrieve the current user ?

waiting for reply.

thanks

Hi,

request.getRemoteUser() should give you the currently logged in user or null if not logged in. You could use the UserModule or UserProfileModule JNDI entries to get the necessary user information.

Hi,

You can use the below mentioned API to get the currently logged in user

renderRequest.getUserPrincipal().getName();

or

actionRequest.getUserPrincipal().getName();
