How to run Rapidminer Process from Java console application?
I built a process in Rapidminer Studio (classification with decision tree/neural net), I would like to load this process and run it with different datasets in a Java console application. I read about this here, but I didn't really found a great tutorial/documentation, how to do this, the basic things (load process, change properties, change the training model, ... ). Any advice would be helpful.

Altair Employee@Thomas_Ott that's not right.As long as it part of the open core you can do this. I think there is no explicit documentation on it though.
Easy way might be to use the CLI.
Best,

Yes, I'd like a simple cli, to load the process and run the process, but I don't really know, how to load a process that I made in Rapidminer, and things like that.
Altair EmployeeHi,
rm already has an CLI. Just go for
rapidminer -f myfile.rmp
or
rapidminer //Local Repository/folder/myprocess
.
That works. You can also provide macros if you want to.
Best,
Martin
Thanks! These informations were really helpful.
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();
Process process = new Process(new File("/MyProcessFile.rmp"));
System.out.println(process.run());
Finally I wrote this, after that I got the result. Maybe it'll be useful for others.

Your best bet is to use RapidMiner Server or getting an OEM license.
