I am not able to put any value in my application using WebDriver. My application is using frames.
I am able to clear the value of my textbox with driver.findEle
Before sendkeys(), use the click() method (i.e., in your case: clear(), click(), and sendKeys()):
driver.findElement(By.name("name")).clear();
driver.findElement(By.name("name")).click(); // Keep this click statement even if you are using click before clear.
driver.findElement(By.name("name")).sendKeys("manish");
