subreport by giving runtime parameter

Hi Admin/Frends,
I give reference to a servlet and also give the parameter value also .E.g
"http://localhost:8080/myapp/subreport1?emp_id=2"
It is working fine but this is hard coding of parameter passing to a subreport.
I want to generate subreports based on the value of the textfield which I hyperlinked to my subreport.
I have one textfield named $F{emp_id}
and in its hyperlinked reference expression I tried to give

"http://localhost:8080/myapp/subreport1?
emp_id=$F{emp_id}"


so that when masterreport runs whatever value it has in this "emp_id " field ,I can pass the same value to subreport to generate data.
but its showing this

http://localhost:8080/myapp/select1.do?emp_id=((java.lang.Integer)field_emp_id.getValue())


I was expecting to get the runtime value of emp_id field of masterreport.

One can say on the fly subreport generation .

Can anybody tried this thing.
Plz help me in this as soon as possible.

here is my previous query
