In my applications, I need to output some xml documents in the portal. these xml documents is generated based on users' userid.
I have tried to use servlet to output xml, but in servlet I can't get the user infomation through the servlet getUserPrincipal(), even if I have logged in the portal .
It is not secure if I direct pass the parameter "userid" to the servlet, right?
Does anybody know how to solve this problem?
