How get textArea using Java with WebDriver?

Question

I have a problem with WebDriver Java class, when I want to get an attribute type "textArea" I get this Exception.

Code:

WebDriver driver = new HtmlUnitDriver(); driver.get("http://www.cmmazzoni.it/index.php?option=com_jdownloads&Itemid=0&view=upload");                

WebElement descriptionOne=driver.findElement(By.name("description"));
descripcionUno.sendKeys("Hola! :D");

Exception:

java.lang.UnsupportedOperationException: You may only set the value of elements that are input         elements
at org.openqa.selenium.htmlunit.HtmlUnitKeyboard.sendKeys(HtmlUnitKeyboard.java:82)
at org.openqa.selenium.htmlunit.HtmlUnitWebElement.sendKeys(HtmlUnitWebElement.java:343)

Code HTML:

<td width="140" valign="top">Descripción Corta:
</td><td width="20" valign="top">&nbsp;</td></tr>
<tr><td colspan="3">
<textarea cols="75" rows="20" style="width:100%; height:350px;" id="description"     name="description"></textarea>
<script type="text/javascript">window.addEvent("domready",function()
{CKEDITOR.config.expandedToolbar = true;
Replacedescription_longTextContainer("description"); 
});
</script><
</td>

Answer 1

It would seem that the name value you are passing to your selenium driver and the name property you are setting up do not match.

Change this: WebElement descriptionOne=driver.findElement(By.name("description")); to this: WebElement descriptionOne=driver.findElement(By.name("description_long"));

It is best for you to use id when it is possible. If element does not have an id then you may use the "cssselector". You just write down the jquery as a parameter to,

driver.findElement(By.cssSelector("jquery"));

For your problem;

driver.findElement(By.id("description"));

driver.findElement(By.cssSelector("#description"));
