Reading documents Integration with java

Question

Hey All,

I am currently working on my graduation project and i have a process in rapid in which i want to input multiple text documents to rapid miner one at a time. The process in rapidminer is working very well however when i try to call it from the java application it keeps getting me errors. Below is the java code. I know that i have a problem to input the file to the code so please any help will be appreciated. Here is my code. I input any parameter as i do not know the right parameter to be input

import com.rapidminer.Process;
import com.rapidminer.RapidMiner;
import com.rapidminer.operator.*;
import com.rapidminer.operator.AbstractIOObject.InputStreamProvider;
import com.rapidminer.operator.text.io.filereader.PDFFileReader;
import com.rapidminer.parameter.Parameters;
import com.rapidminer.tools.XMLException;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class ReadRapidminerProcess {

private static final Parameters PDFFileReader =  new Parameters();
	public static void main(String[] args) throws OperatorException, IOException, XMLException {

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
	      RapidMiner.init();

Process process = new Process(new File("/Users/abdelrahmanayad/Desktop/reading.rmp"));
	      Operator op = process.getOperator("Read CV");
	      op.setParameters(PDFFileReader);
	      
	      process.run();
	    } 
	}

Hi,

1) What errors? I can only guess by looking at your code right now.
2) What process? I'd like the xml of the process to have a look at it.
3) Is the operator really called "Read CV"?
4) You set parameters one at a time. You look up the static variable which is the key for said parameter and then set it, e.g.
operator.setParameter("parameter_key", "parameter_value");
