I don't believe so. However, Java got a built-in JS called Nashorn:

What kind of script; what is it for? There might be other ways of accomplishing whatever you are trying to do....

Hi all, sorry for reply so late but I was busy. I solve my ploblem, it was more easy than I was thinking. Below you can see the solution::

import java.io.IOException;
import org.apache.commons.exec.CommandLine;
import org.apache.commons.exec.DefaultExecutor;
import org.apache.commons.exec.ExecuteException;


public class TestScript {

    int iExitValue;
    String sCommandString;

    public void runScript(String command){
        sCommandString = command;
        CommandLine oCmdLine = CommandLine.parse(sCommandString);
        DefaultExecutor oDefaultExecutor = new DefaultExecutor();
        oDefaultExecutor.setExitValue(0);
        try {
            iExitValue = oDefaultExecutor.execute(oCmdLine);
        } catch (ExecuteException e) {
            System.err.println("Execution failed.");
            e.printStackTrace();
        } catch (IOException e) {
            System.err.println("permission denied.");
            e.printStackTrace();
        }
    }

    public void initScript(){
        TestScript testScript = new TestScript();
        testScript.runScript("node  scrip.js");
    }
}

The nex step is ass the jar file "org.apache.commons.exec", to do this, go to "Sketch ---> Add File ---> org.apache.commons.exec" and thas it.

Thanks for your help.
