How to upload multiple files using Robot class in selenium Webdriver (Mac)?
<p>I am trying to upload a file in selenium webdriver using Robot class and i am using Mac machine. Send keys doesnt work. Below is the code and it works fine when i load a file first time. I am trying to upload another file from the same page again but since the applet is open, no file is getting selected and script fails</p>

<pre><code>browse.click(); // Click on a browse button from the page
File file = new File(photoLocation); //send path of the file

StringSelection StringSelection = new StringSelection(file.getAbsolutePath());

Toolkit.getDefaultToolkit().getSystemClipboard().setContents(StringSelection, null); //Copies the filepath to clipboard


robot = new Robot();

//This launches java applet, so we are using cmd+tab to shift the focus
    robot.keyPress(KeyEvent.VK_META);
    robot.keyPress(KeyEvent.VK_TAB);
    robot.keyRelease(KeyEvent.VK_META);
    robot.keyRelease(KeyEvent.VK_TAB);
    robot.delay(500);

//Open Goto window
    robot.keyPress(KeyEvent.VK_META);
    robot.keyPress(KeyEvent.VK_SHIFT);
    robot.keyPress(KeyEvent.VK_G);
    robot.keyRelease(KeyEvent.VK_META);
    robot.keyRelease(KeyEvent.VK_SHIFT);
    robot.keyRelease(KeyEvent.VK_G);

//Paste the clipboard value
    robot.keyPress(KeyEvent.VK_META);
    robot.keyPress(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_META);
    robot.keyRelease(KeyEvent.VK_V);

//Press Enter key to close the Goto window and Upload window
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);
    robot.delay(500);
    robot.keyPress(KeyEvent.VK_ENTER);
    robot.keyRelease(KeyEvent.VK_ENTER);
</code></pre>

<p>i am using the same code to be called again from the main page to upload the second file. But since the java applet is still open, i am unable to upload the file. Is there a way for me to close the applet?</p>
