【求助】关于selenium在IE8浏览器下运行失败，Could not start a new session

[ganzhouguo]

求助有用过selenium的童鞋们，我在eclipse下运行以下JAVA程序，调用firefox，访问www.baidu.com，输入文字搜索。这个脚本运行正常。
package com.example.tests;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class ExampleForFireFox{

/**
* @param args
*/
public static void main(String[] args) {

System.setProperty("webdriver.firefox.bin", "D:\\Program Files For Work\\Mozilla Firefox\\firefox.exe");
WebDriver driver = new FirefoxDriver();
driver.get("http://www.baidu.com");
System.out.println("1 Page title is: " + driver.getTitle());
WebElement element = driver.findElement(By.id("kw"));
// 输入关键字
element.sendKeys("zTree");
element.submit();
(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return d.getTitle().toLowerCase().endsWith("ztree");
}
});
System.out.println("2 Page title is: " + driver.getTitle());
//关闭浏览器
driver.quit();
}
}

但是当我把其中webdriver换成IEdriver的时候，运行就报错了，代码如下：

package com.example.tests;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class ExampleForInternet {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.setProperty("webdriver.ie.driver","C:\\Program Files\\Internet Explorer\\iexplore.exe");
System.out.println("InternetExplorerDriver opened");
WebDriver driver=new InternetExplorerDriver();
driver.get("http://www.baidu.com/");
System.out.println("InternetExplorerDriver opened"+driver.getTitle());
//WebElement element =driver.findElement(arg0)
WebElement element=driver.findElement(By.id("kw"));
element.sendKeys("你好！");
element.submit();
}
}

报错信息如下：
Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

也不知道是为什么，查询许久未果，求大神帮忙指出问题~~感激不尽

You will need InternetExplorer driver executable on your system. So download it from the hinted source (http://code.google.com/p/selenium/downloads/list) unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe Then you have to set it up in the system. Here is the Java code pasted from my Selenium project: File file = new File("C:/Selenium/iexploredriver.exe"); System.setProperty("webdriver.ie.driver", file.getAbsolutePath()); WebDriver driver = new InternetExplorerDriver(); 要先下载一个iexploredriver才行。

It worked!So kind of you!刚开始捯饬这东西，只是从网上找了个简单的例子跑跑，我想我还没弄清楚它的工作原理，掩面思过。。。 你说的对的，因为selenium无法直接启动IE，所以需要借助IEDriver，我还注意到我代码中有错误，应该是System.setProperty("webdriver.ie.driver","C:\\Program Files\\Internet Explorer\\IEDriverServer.exe");修改后OK了。 Thank you so much!

[他们叫我斌哥]

iexploredriver这个东西怎么得到？

[quelly]

System.setProperty("webdriver.ie.driver","C:\\Program Files\\Internet Explorer\\IEDriverServer.exe");在哪里修改？
