"Rapid miner with java"
I have the following process built in rapidminer using applymodel:

<process version="5.3.000">

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

Maybe this thread will help?
Thank you for the help. But Still doesnt work. when I run the process in Rapidminer, I get back 4 records. But when I run in java see only header information also says ' java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
' if I tried doing ExampleSet es = (ExampleSet) ioResult.getElementAt(1);
Any help is appreciated.
' if I tried doing ExampleSet es = (ExampleSet) ioResult.getElementAt(1);
Any help is appreciated.
Do you have two outputs? The getElementAt using 0-based indexing. To go through the table you should use the iterator of the exampleset.
Cpuld u please give an example, of how to get ExampleSet from the process and iterate through it.
I thought you already had the ExampleSet. (You mentioned only the header was printed.)
So if you have it, this message gives an example how to iterate through it.

Hi,
you can only retrieve the number of result IOObjects your process delivers. In the process you posted there is only one connection to a process result port (bubble on the right side of the canvas). Therefore your IOContainer only contains one item.
