    Hi Andrew,
    sounds really like fun :) I think you will either have to use the Java native interface JNI or use a webservice, which takes the data and runs the process on it and returns the results in an appropriate form. We currently provide some webservices, so if you don't want to write it on your own and host your own server, you might want to contact us.

    Hi Sebastian,
    thanks for reply. I look at JNI, IKVM, webservices and it look great.At this point I decrease my goals and I try using rapidminer in C# app rather than integrating.I choose simple solution via System.Diagnostics.Process.Start() method. However there is some sort of tedious problem. When i run the code in C# in Visual studio 2008 or directly from comand line, it ends up with error: [Fatal] Cannot read config file C:/Program Files/Rapid-I/RapidMiner/scripts/01_ParameterOptimization.xml! Here is the source code:

    static void Main(string[] args)
    {
               
               ProcessStartInfo Info = new ProcessStartInfo("C:/Program Files/Rapid-I/RapidMiner/scripts/rapidminer.bat");
               Info.UseShellExecute = false;
               Info.ErrorDialog = false;
               Info.CreateNoWindow = true;
               Info.RedirectStandardOutput = true;
               Info.Arguments = "C:/Program Files/Rapid-I/RapidMiner/scripts/01_ParameterOptimization.xml";
       
               Process p = System.Diagnostics.Process.Start(Info);

               System.IO.StreamReader oReader2 = p.StandardOutput;
               string sRes = oReader2.ReadToEnd();
               oReader2.Close();
               //All the external programs output is now in sRes
                           
               Console.WriteLine(sRes);
               Console.ReadLine();
               
    }
    I cant imagine where is the bug.In Java via metod RapidMiner. init()  and process.run() everything works well.

    Cheers,
    Andrew

    Hi,
    I guess, your process files is either not existing, misspelled or simply must be quoted.
