"Running an xml process file with the API"

Question

Hi there,
I have an xml process file. It runs fine with the rapidminer GUI. Is it possible to run it from a java application using the API? 
I know one could be rewrite the process using the API 
something like  inputOperator = OperatorService.createOperator("DatabaseExampleSource");
      // set parameters
      inputOperator.setParameter("database_system", "MySQL"); ...

but I just want to run my existing xml process file within an eclipse project.

Thanks. Help is appreciated.

Thanks. It woks fine.
Here my code with the init part:

import java.io.File;
import com.rapidminer.Process;
import com.rapidminer.RapidMiner;
import com.rapidminer.operator.*;

public class executeXMLModel {

public static void main(String[] argv) throws Exception {
  
	  String modelFile="C:/Documents and Settings/emolano/My Documents/rm_workspace/mining/platform/xmlModel.xml";

// set properties to point to plugin directory
      String pluginDirString = new File("C:\Program_Files\Rapid-I\RapidMiner\lib\plugins").getAbsolutePath();
      System.setProperty(RapidMiner.PROPERTY_RAPIDMINER_INIT_PLUGINS_LOCATION, pluginDirString);
      // set properties - rapid miner home
      String path="C:\Program Files\Rapid-I\RapidMiner\";
	  System.setProperty("rapidminer.home",path );
	  
      // initialization
	  RapidMiner.init(false, true, true, true);
	  
	  File processFile = new File(modelFile);
	  if (!processFile.exists()){throw new Exception("File '" + processFile.getAbsolutePath()+ "' does not exist!");}
	  Process process = RapidMiner.readProcessFile(processFile);
	  IOContainer input = new IOContainer();
	  IOContainer output = process.run(input);
         
   }
}

Hello emolano

I assume you have read chapter 7 of the tutorial.pdf.

The requested can be perform like this:
File processFile = new File("d:/test.xml");
if (!processFile.exists()){throw new Exception("File '" + processFile.getAbsolutePath()+ "' does not exist!");}
Process process = RapidMiner.readProcessFile(processFile);
IOContainer input = new IOContainer();
IOContainer output = process.run(input);

hope this was helpful
