Selenium RC
is not maintained anymore, I would recommend you to use WebDriver
instead. Selenium RC
is a Javascript application where as WebDriver uses browsers Native API. Therefore browser interactions using WebDriver are close to what the real user does. Also WebDriver's API is more intuitive and easy to use in my opinion. I don't see HTML in your question, but you could do start with something like this,
WebDriver driver = new FirefoxDriver();
WebElement login = driver.findElement(By.id("empLogin"));
login.click();
