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

	         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();
    Regards,
    Marco
