Question

would like to know how to print the browser the client is using and if OS using jsp. Some people suggested using ${header["user-agent"]} however, this command returns various information and I would like only the browser and the OS.

Answer 1

Take a look at user-agent-utils, with this lib you can easily extract the information you need, for example:

String userAgentStr = request.getHeader("User-Agent");
UserAgent userAgent = UserAgent.parseUserAgentString(userAgentStr);

And in the Useragent object you have methods like getOperatingSystem() and getBrowser(). Javadoc here.
