click file, export, select runnable jar file, click next, select your launch config and destination, finish and you're done.

Then double-click the runnable jar file in the destination you chose.

Hello,
I try to make runnable jar.I have only one class in my project.Here is source code


import com.rapidminer.RapidMiner;
import com.rapidminer.Process;
import java.io.File;



public class rapido {

public static void main(String [] argv) throws Exception{


RapidMiner. init ();

// create the process from the command line argument le
Process process = new Process(newFile("01_ParameterOptimization.xml"));

// run the process on the input
process .run( );

}

}

When i make a jar file and execute it, then in output is something like "could not find the the main class".Any idea?Thanks for any help.

Did you specify which class is your main class in your jar's manifest?

Hello ,
thanks for quick reply.I think that my problem cause the throw exception statement in the signature of main method.When i delete this statement the code didnt work but with it the eclipse didnt recognize the main method in my class during finding the method with main.My knowlege about java is comic. So its kind of funny situation.
