A Simple listener which takes care of starting and stopping the Selenium Server

SeleniumStarterListener

package com.test.listeners;

import org.openqa.selenium.server.RemoteControlConfiguration;
import org.openqa.selenium.server.SeleniumServer;
import org.testng.ISuite;
import org.testng.ISuiteListener;
import org.testng.Reporter;

public class SeleniumStarterListener implements ISuiteListener {
	private static SeleniumServer server = null;
	private static RemoteControlConfiguration configuration = null;
	private static boolean isServerStarted = false;

	public void onStart(ISuite suite) {

		configuration = new RemoteControlConfiguration();
		configuration.setPort(4444);
		try {
			server = new SeleniumServer(configuration);
			server.boot();
			isServerStarted = true;
			Reporter.log("Started the selenium server", true);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public void onFinish(ISuite suite) {
		if (isServerStarted) {
			server.stop();
			Reporter.log("Stopped the selenium server", true);
		}
	}

}

Where is RemoteControlConfiguration and SeleniumServer class.please let me know

I guess they all refer to old selenium RC API which required selenium server to be started before running the test.
Notice that Selenium RC has been deprecated and you should be using WebDriver instead.
