Hi, i have a problem, i can't to execute a plugin of rapidminer. The plugins is /RapidMiner/lib/plugins/rapidminer-Text Processing-5.1.001.jar

This is the code: 

import com.rapidminer.RapidMiner;
import com.rapidminer.Process;
import com.rapidminer.example.Attribute;
import com.rapidminer.example.Example;
import com.rapidminer.example.ExampleSet;
import com.rapidminer.operator.IOContainer;
import com.rapidminer.operator.IOObject;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.OperatorException;



import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import com.rapidminer.operator.io.ExcelExampleSource; 
import com.rapidminer.repository.IOObjectEntry;
import com.rapidminer.repository.ProcessEntry;
import com.rapidminer.repository.RepositoryLocation;
import com.rapidminer.tools.XMLException;

public class Prueba {

	public static void main(String args[]) throws OperatorException, IOException, XMLException {

	    RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
	    
	    RapidMiner.init();
	    
	    Process location = new Process(new File("C:\\Users\\lDanny\\.RapidMiner5\\repositories\\Local Repository\\PrimeraVez.rmp"));
	    IOContainer resultExample = location.run();
	    System.out.println(resultExample.toString());
		System.out.println("am here");
	}
}
and this is error: 

Exception in thread "main" com.rapidminer.operator.UserError: The dummy operator Process Documents from Data (replacing text:process_document_from_data) cannot be executed. 
	at com.rapidminer.operator.DummyOperator.doWork(DummyOperator.java:88)
	at com.rapidminer.operator.Operator.execute(Operator.java:867)

	at com.rapidminer.operator.ExecutionUnit.execute(ExecutionUnit.java:711)
	at com.rapidminer.operator.OperatorChain.doWork(OperatorChain.java:375)

	at com.rapidminer.Process.run(Process.java:832)
	at com.rapidminer.Process.run(Process.java:827)
	at com.rapidminer.Process.run(Process.java:817)
	at fdf.Prueba.main(Prueba.java:34)
I tryn to add  <property name="extension.dependencies" value="lib/plugins/rapidminer-Text Processing-5.1.001.jar" /> in build.xml but i have the same error.

Thanks.

    Hi,

    1) That extension looks mighty old. Please use the 5.3.x version of it.
    2) If it still does nto work, please post the full log when you execute your application.

    Regards,
    Marco

    Hi,

    to get the extension to load from a development environment, it either has to be a managed extension (USER_HOME/.RapidMiner/managed) defined in the managed.xml, or it has to be in the WORKSPACE/RAPIDMINER_PROJECTNAME/lib/plugins folder.

    Regards,
    Marco

    Hi,

    then it fails to use the correct home folder. See the following log part: 

    Información: Property rapidminer.home is not set. Guessing.
    Apr 08, 2014 7:20:44 PM com.rapid_i.Launcher ensureRapidMinerHomeSet
    Información: Trying base directory of classes (build) 'C:\Users\lDanny\workspace\fdf'...gotcha!
    RapidMiner Home is the root folder of the RapidMiner Studio installation. In that folder it will try to locate /lib/plugins to load extensions. You can set rapidminer.home via system property before calling RapidMiner.init() to the correct folder, e.g. 

    System.setProperty("rapidminer.home", "C:\Users\lDanny\workspace\rapidminer");
    Regards,
    Marco
