driver.wait() throws IllegalMonitorStateException

All the variations of wait(...) are throwing the below exception from the following code. What am I doing wrong?

java.lang.IllegalMonitorStateException
at java.lang.Object.wait(Native Method)
at java.lang.Object.wait(Object.java:485)
at LoginPage.main(LoginPage.java:29)

try
{
driver.get("http://domain:port/coco/webapp/login/login.faces");

driver.findElement(By.id("clientCode")).sendKeys("coco");
driver.findElement(By.id("systemCode")).sendKeys("consumer");
driver.findElement(By.id("userId")).sendKeys("ffadmin");
driver.findElement(By.id("password")).sendKeys("password");

driver.findElement(By.className("af_commandButton")).click();
driver.wait();
Assert.assertTrue(driver.getPageSource().contains("Administration"));

}
catch (Exception e)
{
e.printStackTrace();
}

Answer

You can only wait on an object if you've acquired the lock for it using synchronized.

I don't know whether you're meant to use wait using WebDriver - if you are, you'd need something like:

synchronized (driver)
{
    driver.wait();
}

However, if you're waiting for something to occur, it's more likely that there's an alternative method you're meant to be using. Perhaps WebDriverWait?
