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.*;

public class GUILauncher extends JFrame implements ActionListener{

new GUILauncher();
try {

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");

// 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

Aldi

    hi @Aldi I'm not an expert on the license differences between the package and compiling the open source version. You may be right about the concurrency decision tree. I know there's an old decision tree that is not parallelized that may be open source? Or you can use the Weka W-J48 decision tree from the Weka extension which should work.

    And yes Naive Bayes is always a safe choice ;)
