Robot execution on local machine, Control Tower, and RPA Node

One of common issues with Groovy RPA scripts is: a script is successfully executed on a local machine (WF Studio), but fails when it is executed in Control Tower as a Bot Task.

To avoid this issue, you need to know the following rules:

  • If you want the script to be executed on the RPA Node machine (RPA Windows server):
    1. Put the script inside this method: desktopDriver.executeScript(script, "GROOVY")
    2. The code above should be inside the <robot> plugin.
  • If you want the script to be executed on your local machine:
    1. Write your code inside a <script> section.
    2. Run Bot config from WorkFusion Studio.
  • If you want the script to be executed on the Control Tower server (typically it is a Linux machine):
    1. Write your code inside a <script> section.
    2. Export your config to Control Tower as a Bot Task and place it in a business process.
    3. Run your business process.

Therefore, you need to pay attention to the file paths you are using in your scripts: C:/tmp/test/1.txt - will not exist on a Linux machine (Control Tower).**

If you have this file on your local machine, make sure it is accessible under the same path on the target RPA Node.

See the following examples for better understanding (comment blocks show where the script will be executed):

Example 1

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="http://web-harvest.sourceforge.net/schema/1.0/config" scriptlang="groovy">

    <var-def name="copyFile">
        java.io.File sourceFile = new java.io.File("C:\\tmp\\test\\1.txt");
        java.io.File destFile = new java.io.File("C:\\tmp\\test\\345.txt");
        java.io.InputStream is = null;
        try {
            is = new java.io.FileInputStream(sourceFile); 
            java.nio.file.Files.copy(is, destFile.toPath(), java.nio.file.StandardCopyOption.REPLACE_EXISTING);
        } catch(Exception e) {
            e.printStackTrace();
        } finally {
           if (is != null) is.close();
        }
    </var-def>
    
    <!-- executing on WF or Studio machine (JVM) -->
