RapidMiner and Java integration

kkdataminer

Hi There,

 

I wrote a Java program which generates a results excel file. I want to use this results excel file dynamically as an input to RapidMiner process inside a java application.

In another terms, when I run rapidMiner process from Java application , it should read results excel file which is generated by Java program and run rest of the process.Any help on this would be greatly appreciated.

 

Thanks

I changed the operator to Read Excel and it worked fine. Closing this issue

Hi there, I am not totally sure what the question is, since RapidMiner Studio has a native "read Excel" operator that should enable you to read the excel file you have produced without difficulty.  However, if you are looking for functionality for RapidMiner to kick off a process automatically whenever that file is produced, then you will need to utilize RapidMiner Server in addition to RapidMiner Studio.  Studio alone doesn't allow the batch scheduling of jobs or jobs to be based on triggers, but Server does.  There is a free version of Server available and lots of resources here on getting that set up.  In fact I wrote a blog post just last week about how to set one up on AWS for free, so if you are interested in that you can check it out here: https://rapidminer.com/installing-rapidminer-server-aws/

 

There is also a Server forum where you can ask any questions you might have about scheduled or triggered jobs.

Another thought is to use the Execute Program operator in Studio. This way you can kick off your Java program inside the process and load in whatever results your Java program returns.

I wrote the below code. RPM process is reading the excel from Local Repository instead of the path mentioned in the java code. Am I missing something here? How to make the RPM process read the excel from local drive? Any help on this would be greatly appreciated.

 

import com.rapidminer.Process;
import com.rapidminer.RapidMiner;
import com.rapidminer.example.ExampleSet;
import com.rapidminer.operator.IOContainer;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.OperatorException;
import com.rapidminer.operator.nio.ExcelExampleSource;
//import com.rapidminer.operator.io.ExcelExampleSource;
import com.rapidminer.tools.XMLException;
import java.io.File;
import java.io.IOException;
public class Sample_RapidMiner {
public static void main(String[] args) throws XMLException, OperatorException {
try {
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();
Process process = new Process(new File("C:\\Users\\koushik\\Documents\\Java RapidMiner Integration\\RapidMinerInJava\\RapidMinerInJava\\BPDictionaryOutputCount.rmp"));
Operator op = process.getOperator("Retrieve");
op.setParameter(ExcelExampleSource.PARAMETER_EXCEL_FILE, "C:\\Users\\koushik\\Documents\\Java RapidMiner Integration\\RapidMinerInJava\\BPDictionary.xlsx");
process.run();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}

Can you just use the RapidMiner Server to do this?
