I have the following process built in rapidminer using applymodel:

I want to use this process in java.Below is the code :
RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
RapidMiner.init();
try {
File processFile = new File("\\Local Repository\processes\TrainingDataProcess.rmp");
Process process = new Process(processFile);
IOContainer ioResult = process.run();
if (ioResult.getElementAt(0) instanceof ExampleSet) {
ExampleSet resultSet = (ExampleSet)ioResult.getElementAt(0);
System.out.println("Success readresultSet: "+resultSet);
}
} catch (Exception e) {
RapidMiner.quit(RapidMiner.ExitMode.ERROR);
when I run the program, get back the header information but not the actual result set. am I missing something. Thank you for the help in advance
