Exception in thread "main" com.rapidminer.operator.UserError

Fireholder

I have following Eclipse program:
import com.rapidminer.tools.OperatorService;
import com.rapidminer.RapidMiner;
import com.rapidminer.Process;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.OperatorException;
import com.rapidminer.operator.IOContainer;
import java.io.IOException;
import java.io.File;
public class FirstClass {
static File x=new File ("/home/prakt/workspace-rapidminer/Project/FirstProcess.rmp");
public static void main(String[] argv) throws Exception {
 
  RapidMiner.init();
 
 
  Process process = new Process(x);
    process.run();
}

}
I have tried to run the code but encountered several  errors like:

Exception in thread "main" com.rapidminer.operator.UserError: Cannot retrieve repository data from entry '//NewLocalRepository/Project/Golf'. Reason: Requested repository NewLocalRepository does not exist..

Hi Fireholder,

since I've been doing some integration testing for a few days I should be able to help you with that.
It seems that repositories are not available but looking for the reason could have been easy if I had really payed more attention to all of the initialitzation messages before.

One line said:

Apr 19, 2011 10:54:26 AM com.rapidminer.repository.RepositoryManager load
INFO: Cannot access file system in execution mode UNKNOWN. Not loading repositories.

So you just have to set the ExecutionMode before you call RapidMiner.init() like this:

RapidMiner.setExecutionMode(ExecutionMode.EMBEDDED_WITHOUT_UI);

But don't ask how the available modes differ or which one really makes sense. Didn't notice any relevant difference between the EMBEDDED ones or COMMAND_LINE so far. But I am still doing the first steps, so this doesn't have to mean anything...

Regards
Matthias
