  <pre class="lang-java prettyprint-override"><code>public class Simple {
  
  WebDriver driver = new FirefoxDriver();
  String baseUrl;
  
      @Test
      public void f() {
          WebElement abc = driver.findElement(By.xpath("//table/tbody/tr[2]/td/table/"+
                        "tbody/tr[5]/td[3]/input"));
          abc.sendKeys("Jaivir");
      }
  
      @BeforeTest
      public void beforeTest() {
          baseUrl ="http://localhost:8657/NutechDiagnostics/AcceptTest.jsp";
          driver.get(baseUrl);
      }
  
      @AfterTest
      public void afterTest() {
          driver.quit();
      }
  
  }    
  
  baseUrl given is completely accurate. Is it the problem of browser. Please help me i 
   am getting stuck here for a lot of time. Thanks in advance.
