What do you want is the referer to the servlet but I think you can't get this information in the servelt automatically.
What you could try is to add this information to your first page, so that it's communicated to the servlet.

An example to do it via Javascript is above:

<html>
<head>
     <title>Untitled</title>
</head>

<body onload="document.ip.domain.value=document.domain">

<form name="ip" action="servlet">
<input type="Hidden" name="domain" value="">
<input type="Submit" onClick="alert(document.ip.domain.value); return false;">
</form>


</body>
</html>

It passes the name you used to get to the server (which is not always the ip address).

Cheers,

Raffaele

I think you should be able to get the referrer with the getHeader(String) method of HttpServletRequest.

Hi,
  Use HttpServletRequest.getRequestURL().
 This will give u the address. I think u know how to convert this to the ip address using the java.net package.

regards
Rajesh
