How to create a session by AppsLocalLogin.jsp

Question

first, in auth.jsp we check fnd_global.user_name against "ANONYMOUS" to see whether user is logged on.
if not, we invoke AppsLocalLogin.jsp to create a session.
http://server:port/OA_HTML/AppsLocalLogin.jsp?requestUrl=report.jsp%3Fparam1%3Dyyy
the login page shows, page re-directed to report.jsp.
however fnd_global.user_name doesn't work. it still returns "ANONYMOUS".
if user logged on OA normally, then the whole thing worked. it seems fnd_global.user_name doesn't like the way we login.
how should we invoke AppsLocalLogin.jsp so it'll create a proper session?
part of report.jsp:
WebAppsContext ctx =WebRequestUtil.validateContext(request, response);
conn = ctx.getJDBCConnection();
sql = "select fnd_global.user_name from dual";
(we tried to invoke RF.jsp instead.
doesn't work because we don't know how to pass the param1 to report.jsp thru RF.jsp)

Answer 1

This is variable what is working in my aplication
String variable;
if(user == null){
               user=new String("");
     }//if you don'y do this you will have null pointer exception
session.setAttribute("user",user);//put value
          String name=(String)session.getAttribu("user");      //get value;
I hope this will help
