There are no errors? Have you looked at the log files?

kssraju

i havent seen any errors ..

iam able to see the report fine with direct access to

http://localhost:8080/birt/frameset?__report=test.rptdesign

but my requirement is , i will hame my webapp WebAppA and BIRT web appp birt.war willl deployed

i dont want direct access to birt,through my ServletA in WebAppA i will call birt report and show to user.

my observation from browser firefox web console is

1. if i acesss http://localhost:8080/birt/frameset?__report=test.rptdesign

a. call is going to processing.jsp and after loading report viewer the call is going to frameset again with
parameters __report and seesionID

2.if i access using

URL parURL = new URL("http://localhost:8080/birt/frameset?__report=test.rptdesign");
HttpURLConnection urlConnection =
(HttpURLConnection) parURL.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);

the call is going to processing.jsp and i havent seen the call again to frameset with
parameters __report and seesionID

My Requirements are

1. i want to generate BIRT report and show to user along with paging and export options, i can generate a HTML or PDF and send it back the content to user ,but i need BIRT viewer kind of reponse needs to be presented to user

2. i dont want client to know the birt servlet is giving the response,that is the interstion of call birt viewer from my ServletA instead of direct acess to birt web app

Please suggest any approches to fulfill my requiremnts...

Thank you
