Hi,
Using my local development environment, I put your form in an <iframe>, and after hitting submit, I had a servlet send back the info that was entered, and I was successfully able to display all the data using your code:
String[] aa=req.getParameterValues("aa");
So, there is nothing inherent in an iframe that prevents you from doing that. An <iframe> is just a browser window like any other, and it makes requests to the server--it just happens to be imbedded in another browser window.
Are you getting any compiler errors? What are they? Are you getting any servlet errors when you submit the form?
I suggest you try to get a simple app working, like I did. Create a simple html page with an iframe that displays a form in the iframe. Then, code a servlet that just displays in the iframe what was entered
[nobr]<form action="http://localhost:5050/examples/servlet/post_register" method=post>

>>I want to get data for insertion into DB from iFrame
1) Then why is the form you posted relevant? It's not displayed in the <iframe>?
2) You don't call servlets like this:
action="http://localhost:5050/examples/servlet/post_register"
For the action attribute, you use a made up name and extension, like "ParisHilton.do". Then you use servlet mapping in the web.xml file to map the made up name to your servlet, which should be located in the WEB-INF/classes directory.
What book are you studying?

Very honestly i am very new to servlet and trying to seek as much as I can and I learned a lot from java forums. very frankly I didn't understand that you said above due to lack of knowledge
please get me example by implementing codes
> What book are you studying?
Deitel & Deitel (but it has a small part of servlets. Can you please recomend any servlet book .
thanks
7stud
I also commit that am new as well but I can say that nobody can challenge that I am the one & only master
anyhow thanks for your replies
codes means to say that can u get me an example
you use a made up name and extension, like "ParisHilton.do". Then you use servlet mapping in the web.xml
TIA
