Integrating Nashorn with robotic process automation (RPA)

In the world of automation, Robotic Process Automation (RPA) is becoming increasingly popular. RPA enables businesses to automate repetitive and mundane tasks, freeing up human resources for more complex and strategic activities. One tool that can be leveraged in RPA is Nashorn, a JavaScript engine built into Java.

What is Nashorn?

Nashorn is a JavaScript engine introduced in Java 8, which allows developers to execute JavaScript code within the Java Virtual Machine (JVM). It comes bundled with the Java Development Kit (JDK) and provides seamless integration between Java and JavaScript.

Benefits of Integrating Nashorn with RPA

Integrating Nashorn with RPA can offer several benefits:

  1. Simplified Integration: Since both Nashorn and RPA are based on Java, they can easily communicate with each other without the need for additional libraries or dependencies.

  2. Powerful Scripting: Nashorn enables developers to write powerful JavaScript scripts to automate complex business processes. JavaScript is widely known and has a large developer community, making it accessible for RPA developers.

  3. Access to Java Libraries: By using Nashorn, RPA developers can utilize the vast array of Java libraries and frameworks, enhancing the capabilities of their automation scripts.

  4. Cross-platform Compatibility: RPA tools often support multiple operating systems. Nashorn, being part of the Java ecosystem, ensures that scripts written once can run seamlessly on different platforms.

Integrating Nashorn with RPA

To integrate Nashorn with RPA, follow these steps:

  1. Set Up Your RPA Environment: Install and configure your preferred RPA tool, ensuring it has Java support.

  2. Create Scripts: Write your automation scripts using JavaScript and Nashorn. These scripts can leverage the RPA tool’s API and interact with the application you want to automate.

    var rpa = new Rpa();
var window = rpa.openWindow("https://example.com");
var textField = window.findElement("input[type=text]");
textField.setValue("Hello, world!");

  3. Invoke Scripts from RPA: In your RPA tool, invoke the Nashorn JavaScript engine and execute your scripts.

    NashornScriptEngine scriptEngine = (NashornScriptEngine) new ScriptEngineManager().getEngineByName("nashorn");
scriptEngine.eval(new FileReader("path/to/your/js/script.js"));

  4. Handle Script Output: Retrieve any output or errors generated by the script and handle them accordingly in your RPA tool.

Conclusion

Integrating Nashorn with RPA provides a powerful and flexible approach to automate business processes. By leveraging the capabilities of Nashorn’s JavaScript engine, RPA developers can create sophisticated automation scripts that interact with applications and systems. This integration not only simplifies the automation process but also opens up a world of possibilities by utilizing the wide range of Java libraries and frameworks available.
