# Connect to Headless With Java Function Stack

In this section you will find the required scripts to connect to a headless remote browser using the Java function stack, with a browser automation library of your preference. 

> **Note:** Puppeteer is not available in the Java function stack.

### Playwright

#### Using Playwright Without SmartBrowz

```java
package org.example;
import com.microsoft.playwright.*;
import java.nio.file.Paths;
public class PlaywrightJava {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
        try (Browser browser = playwright.chromium().launch()) {
          BrowserContext context = browser.newContext();
          Page page = context.newPage();
          page.navigate("http://example.com/"");
          page.screenshot(new Page.ScreenshotOptions().setPath(Paths.get("screenshot.png")));
      }
    }
  }
}
```

#### Using Playwright With SmartBrowz

```java
// From inside your Java application
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
BrowserType browserType = playwright.chromium();
//Change browserType.launch with connectOverCDP
    Browser browser = browserType.connectOverCDP("YOUR_CDP_ENDPOINT");
    // The rest of your code remains the same
    Page page = browser.newPage();
    page.navigate("https://www.example.com");
    page.screenshot(new Page.ScreenshotOptions().setPath(Paths.get("screenshot.png")));
  }
}
```

> **Note:** Copy the CDP Endpoint present in the console and paste it in line "**8**" when you implement this code.

### Selenium

#### Using Selenium Without SmartBrowz

```java
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import java.io.File;
import java.io.IOException;
public class ScreenshotDemo {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path\to\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://demoqa.com");
        File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(screenshot, new File("path\\to\\homePageScreenshot.png"));
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
        driver.close();
    }
}
```

#### Using Selenium With SmartBrowz

```java
// From inside your Java application
public static void main() throws MalformedURLException {
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--no-sandbox");
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--disable-dev-shm-usage");
//Change ChromeDriver with RemoteWebDriver
WebDriver driver = new RemoteWebDriver(new URL("YOUR_WEBDRIVER_ENDPOINT"),chromeOptions);
// The rest of your code remains the same
driver.get("https://www.example.com");
driver.quit();
}
```

> **Note:** Copy the Webdriver Endpoint from the console and paste it in the line "**9**" when you implement this code.
