Hi, First I created a portlet that show a button or link when click will call processAction (in doView mode) and sendRedirect to myWebapp in processAction method of this portlet. Then, I created a module to check user information in my webapp (use getRemoteUser). In case the return value is null, I make a forward to login page of portal.
