How to load dataset from Java application to a Rapidminer process?

This is my rapidminer process, and I can load it to my Java application, and run it, after that print out the result, what I see in Rapidminer Studio. My problem is, I don't know how can I add a dataset from the app to the loaded project, instead of using retrieve box, before set the role?

Not sure on where all your data is coming from but if you want to load multiple data sets you could use a Read CSV or Read XLS operator in conjuction with a Loop Files or Loop operator, instead of the Retrieve operator. The Retrieve operator is a RapidMiner optimized data repository, but the data can come from CSV, databases, Hadoop, etc. You don't really need to Load Data > Store in Repository > Retrieve Data > Process, you can just Load Data > Process

Thanks, it's really useful, I see that. Another thing, I wrote a sample code, to run a process within Java code, I'd like to say to the loaded process, before it runs, what csv file it has to use, is it possible?

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();

Process process = new Process(new File("testProcess.rmp"));
System.out.println(process.run());
