Hei..
I`ve try the APi, but i still dont know how to see the output on my process..
here the console says:


Jan 17, 2012 9:53:17 AM com.rapidminer.tools.WrapperLoggingHandler log
INFO: No filename given for result file, using stdout for logging results!
Jan 17, 2012 9:53:17 AM com.rapidminer.Process run

and here is the code

	         StringBuffer fileData = new StringBuffer(1000);
	         BufferedReader reader = new BufferedReader(

	         char[] buf = new char[1024];
	         int numRead=0;
	         while((numRead=reader.read(buf)) != -1){
	             String readData = String.valueOf(buf, 0, numRead);
	             fileData.append(readData);
	             buf = new char[1024];
	         }
	         reader.close();
	         return fileData.toString();
	     }
	 	public static void main(String[] argv) throws Exception {
		   // MUST BE INVOKED BEFORE ANYTHING ELSE !!!

		   RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
		   RapidMiner.init();
		   Process process=new Process(readFileAsString(x));
		   IOContainer ioResult = process.run();
		   if (ioResult.getElementAt(0) instanceof ExampleSet) {
			   ExampleSet resultSet = (ExampleSet)ioResult.getElementAt(0);
               RepositoryLocation resloc = new RepositoryLocation("//MyRepository/contohg");
               RepositoryManager.getInstance(null).store(resultSet, resloc, null);
			   }

		   process.run();
		}

	}

so what should i do next, if i want to see the output?

Hi,
you can just use:


IOContainer c = process.run();
ExampleSet es = c.get(ExampleSet.class);

Hi staryvena,
thx for your reply..

I`ve add the code, but its appeared error

Exception in thread "main" com.rapidminer.operator.MissingIOObjectException: The operator needs some input of type com.rapidminer.example.ExampleSet which is not provided.

so how i can provided the input??
I want to use data source from excel type...

Hi,


IOConatine in = ....
IOContainer c = process.run(in);

Check Process API http://rapid-i.com/api/rapidminer-5.1/com/rapidminer/Process.html and I think if you search this forum, there are some examples.

Best,
Vaclav

ok, somehow i can read the output...
here is my code:


 public class Main {
	 	static String line;
	 	static String x="C:\\Documents and Settings\\user\\My Documents\\RapidMiner\\model1.rmp";
	 	 private static String readFileAsString(String filePath)
	     throws java.io.IOException{
	         StringBuffer fileData = new StringBuffer(1000);
	         BufferedReader reader = new BufferedReader(
	                 new FileReader(filePath));
	         char[] buf = new char[1024];
	         int numRead=0;
	         while((numRead=reader.read(buf)) != -1){
	             String readData = String.valueOf(buf, 0, numRead);
	             fileData.append(readData);
	             buf = new char[1024];
	         }
	         reader.close();
	         return fileData.toString();
	     }
	 	public static void main(String[] argv) throws Exception {
		   // MUST BE INVOKED BEFORE ANYTHING ELSE !!!

		   RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
		   RapidMiner.init();
		   Process process=new Process(readFileAsString(x));
		   IOContainer ioResult = process.run();
           System.out.print(ioResult.getElementAt(0));
           ExampleSet resultSet = null;
           if(ioResult.getElementAt(0) instanceof ExampleSet)
               {
               resultSet = (ExampleSet) ioResult.getElementAt(0);
               RepositoryLocation resloc = new RepositoryLocation("//MyRepository/coba2");
               RepositoryManager.getInstance(null).store(resultSet, resloc, null);
               }
           for(Example example: resultSet){
               Iterator<Attribute> allAtts = example.getAttributes().allAttributes();
               
               //System.out.print(name);
               while(allAtts.hasNext()){
                   for(int i=0;i<=8;i++){
                       Attribute a = allAtts.next();
                   if(a.isNumerical()){
                       double value = example.getValue(a);
                       System.out.print(value);
                       }
                   else{
                       String value = example.getValueAsString(a);
                       System.out.print(value);
                   }
                   }System.out.print("\n");
               }
		}
           }
	}

and the output i get is:

Hi,
Did you look at the Api for the Attribute class?
To get the name of an attribute, you can simply call


attribute.getName();
