How to get user id from different webapp (servlet)

[Rupesh Chotai，修改在10 年前。]

Hi,
We have another webapp (servlet) running in parallel with Liferay portal on the same tomcat. From view.jsp of portlet, an Ajax request has been made to the servlet in this webapp. How to retrieve the user id/user details of logged in liferay portal user in that another webapp (servlet)?

I tried with below code snippet in doGet() method of servlet, but it always return userId as zero.

long userId = PortalUtil.getUserId(httpServletRequest);

Is there a way I can handle this?

Hey Rupesh,

Try the following, it may work:

httpServletRequest.getRemoteUser()

HTH.
