How to show browser info(name,version) and OS name using java in client side.


step1 - use this google api for user agent string parsing.

http://code.google.com/p/user-agent-parser-java/

or
 UserAgentDetails.java

package com.demo;

      UserAgentDetails(String browserName, String browserVersion, String browserComments) {
        this.browserName = browserName;
        this.browserVersion = browserVersion;
        this.browserComments = browserComments;
    }

    public String getBrowserComments() {
        return browserComments;
    }

    public String getBrowserName() {
        return browserName;
    }

    public String getBrowserVersion() {

}
