"Integrating RM5 process in a Java application"

Hi, I have a little rapid miner 5 process that simply reads a csv, changes attribute to label and then i aply a decision tree. It runs ok.

How can I export that process in order to be possible to run it from a Java application?
Any little sample would be very appreciated.

Suppose I have defined these two operators:

Operator inputOperator = OperatorService.createOperator("read_csv.class");
inputOperator.setParameter("file_name","C:\\ing.csv");

Operator inputOperator2 = OperatorService.createOperator("set_role.class");
inputOperator2.setParameter("name","value");
inputOperator2.setParameter("target_role","label");

How do I connect the read CVS to the setRole operator?

Thanks a lot

Hi,
you could save a process designed in RapidMiner to xml and then load it using new Process(file) and execute it via process.run.

Thank you Sebastian.

I used the option menu File|Export process to write it to xml file. Then when i try to load it the compiler says:

[Fatal Error] :1:1: Content is not allowed in prolog.
com.rapidminer.tools.XMLException: Cannot parse document: Content is not allowed in prolog.
at com.rapidminer.Process.readProcess(Process.java:887)

Any help?

Hi,
would you post or attach a link on this process file?

How sad... it was invisible characters :-(

It is running now very well.

Thank you.
