How to run Selenium webdriver on IE

I tried to change selenium webdriver - driver server from Firefox to IE ,and encountered several problem. after googling on internet and doing some search,finally resolved it. To keep improving myself, I write down some of the problems I met. It's better
to set the IE as below to aviod issues.

(the envrioment is IE 9.0 , IEDriverServer_x64_2.39.0,selenium-java-2.38.0.zip,selenium-server-standalone-2.38.0)

1. IE driver server address needed to specified by command below, otherwise ,the webdrive cannot find the IE driver server

System.setProperty("webdriver.ie.driver", "the path of the IEserve)

2. IE zoom should be set to 100%

ieCapabilities.setCapability("ignoreZoomSetting", true);

3. The security level for each website should be equal, (after I resolvedthe "cannot find element” issue, I find this setting has nothing to dowith the problem)

DesiredCapabilities ieCapabilities =DesiredCapabilities.internetExplorer();

ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);

WebDriver wd = new InternetExplorerDriver(ieCapabilities);

4.Maxmize the window opene,otherwise the element is hard to find even it's working fine on FF.
