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

copy
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

copy
// 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

copy
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

copy
// 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.
