The following code should get you started... One of the headers outputted
in this snippit is "User-Agent" so you can parse the string to get what you
are after. I use it in a servlet for debugging purposes so out is an
instance of java.io.PrintWriter from the code PrintWriter out =
response.getWriter(); and response is an instance of interface
javax.servlet.HttpServletResponse.
Enumeration enum = request.getHeaderNames();
if (enum.hasMoreElements()) {
out.println("<H1>Request headers</H1>");
out.println("<PRE>");
while (enum.hasMoreElements()) {
String strName = (String)enum.nextElement();
out.println(" " + strName + ": " + request.getHeader(strName));
}
out.println("</PRE>");
}
The output will look something like the following:
Request headers
Accept: application/vnd.ms-excel, application/msword, application/vnd.ms-powerpoint,
image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
application/pdf, */*

Subject: [jdjlist] Browser detection on server side
I'm looking for code that will reliably extract the following
information from the USER_AGENT string, as seen by a web server:
Browser type (at least MSIE, Netscape, Mozilla) and version.
OS Platform (e.g., PC, Unix, Macintosh) and version
(Win95/98/Me/2K/NT/XP, Mac OS9/OSX, etc.)
I've got some code, it needs to be updated, and I figured "someone must
have written this." I found this package,
http://dhtmlkitchen.com/java/uacheck/index.jsp (Click "Download" tab for
Java code), which is close, but doesn't give me the browser version
(except for IE).
Thanks.
