Java 错误：找不到元素q…Eclipse中的SeleniumRC…提供了堆栈跟踪和代码..请解决？

下面的代码是用Java为Selenium编写的代码，并尝试在Selenium独立服务器中执行/运行。但是，获取一个附加stacktrace的错误

package package1_IdentifyPageOpened;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import com.thoughtworks.selenium.*;

public class Class1 {

Selenium selenium=null;
@Before
public void setUp() throws Exception {


selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://www.portware.com");
selenium.setSpeed("1000");
selenium.start();
//selenium.open();
}
@Test
public void testExported() throws Exception {
selenium.open("/selenium/search.php");
selenium.type("q", "Selenium-RC");
selenium.click("btnG");
}
@After
public void tearDown() throws Exception {
selenium.stop();
}




/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub

}

}

Stacktrace:

我已经尝试过打开浏览器“firefox”（代码中给出的浏览器），然后执行testcase，并给出执行testcase的时间（即setSpeed-1000），因为这些是在早期实例中提供的一些解决方案。但是，还是无法解决。救命啊

此URL无效-。Selenium打开此URL并检查名为“q”的元素。由于页面不存在，因此无法找到元素。

此URL不存在，因此selenium无法找到元素。请验证您的URL。
