Problem while integrating RapidMiner using Eclipse

Hello, I am trying to integrate RapidMiner into my Java Application using Eclipse, I was trying to use the model in my process and extract the results (tree, performance, and table) and show them in my application. But there were a few errors, here are the code and the output.

import java.awt.*;
import java.awt.event.ActionEvent;

import javax.swing.*;

public class GUILauncher extends JFrame implements ActionListener{
public static void main(String args[]) throws Exception {
// System.setProperty(PlatformUtilities.PROPERTY_RAPIDMINER_HOME, Paths.get("").toAbsolutePath().toString());
// RapidMinerGUI.registerStartupListener(new ToolbarGUIStartupListener());
// RapidMinerGUI.main(args);
new GUILauncher();
try {
System.setProperty(PlatformUtilities.PROPERTY_RAPIDMINER_HOME, Paths.get("").toAbsolutePath().toString());
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();
Plugin.setPluginLocation("D:/RapidMiner Studio/lib/plugins");
Plugin.addAdditionalExtensionDir("D:/RapidMiner Studio/lib/plugins");
Plugin.setInitPlugins(true);
Repository repo = RepositoryManager.getInstance(null).getRepository("Projects");
RepositoryProcessLocation processLocation = new RepositoryProcessLocation(new RepositoryLocation(repo.getLocation(), "Process_25%"));
Process process = processLocation.load(null);
// Operator tree = process.getOperator("Decision Tree");
// tree.setParameter("criterion", "information_gain");
// tree.setParameter("maximal_depth", "6");
// tree.setParameter("apply_pruning", "true");
// tree.setParameter("confidence", "0.5");
// tree.setParameter("apply_prepruning", "true");

// tree.setParameter("minimal_leaf_size", "2");
// tree.setParameter("minimal_size_for_split", "4");
// tree.setParameter("number_of_prepruning_alternatives", "3");
// IOContainer container = process.run();
// for (int i = 0; i < container.size(); i++) {
// IOObject ioObject = container.getElementAt(i);
// System.out.println(ioObject);
// }
process.run();
} catch (IOException | XMLException ex) {
ex.printStackTrace();
}
}
}
And here is the output:

In my understanding, I feel like the last error (Exception in thread "main" com.rapidminer.operator.UserError: The dummy operator Decision Tree (replacing concurrency:parallel_decision_tree) cannot be executed.) seems to be the most severe one? Does anybody know how to fix this error? Or what I did wrong? Thank you for the help, highly appreciated.

Best regards

    hi @Aldi I'm sorry no one has chimed in here. Is this still an issue?

    hi @sgenzer I think the problem is that I didn't have the required licenses to use the decision tree operator right? I changed it to Naive Bayes and it worked.
