When i try to run this in eclipse:

import java.io.File;
import java.io.FileWriter;

public class CDUtils {
  private CDUtils() {  }

  public static void open(String drive) {
    try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new java.io.FileWriter(file);
        String vbs = "Set wmp = CreateObject(\"WMPlayer.OCX\") \n"
                   + "Set cd = wmp.cdromCollection.getByDriveSpecifier(\""
                   + drive + "\") \n"
                   + "cd.Eject";
        fw.write(vbs);
        fw.close();
        Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // thanks to TrueJavaProgammer for the waitFor() tip!      
        // Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // Thread.sleep(2000);
    }
    catch(Exception e){
        e.printStackTrace();
    }
  }

  public static void close(String drive) {
    try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new FileWriter(file);
        // to close a CD, we need eject two times!
        String vbs = "Set wmp = CreateObject(\"WMPlayer.OCX\") \n"
                   + "Set cd = wmp.cdromCollection.getByDriveSpecifier(\""
                   + drive + "\") \n"
                   + "cd.Eject \n "
                   + "cd.Eject ";
        fw.write(vbs);
        fw.close();
        Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // thanks to TrueJavaProgammer for the waitFor() tip!      
        // Runtime.getRuntime().exec("wscript "+ file.getPath());
        // Thread.sleep(2000);
    }
    catch(Exception e){
        e.printStackTrace();
    }
  }
}

It asks me if I want to run it has a java application or java applet, I get a error either way: 'selection does not contain a main type'

You need a main method if you want to run it and not just import it as a class.

import java.io.File;
import java.io.FileWriter;

public class CDUtils {
  private CDUtils() {  }

  public static void main(String[] args) { }

  public static void open(String drive) {
    try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new java.io.FileWriter(file);
        String vbs = "Set wmp = CreateObject(\"WMPlayer.OCX\") \n"
                   + "Set cd = wmp.cdromCollection.getByDriveSpecifier(\""
                   + drive + "\") \n"
                   + "cd.Eject";
        fw.write(vbs);
        fw.close();
        Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // thanks to TrueJavaProgammer for the waitFor() tip!
        // Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // Thread.sleep(2000);
    }
    catch(Exception e){
        e.printStackTrace();
    }
  }

  public static void close(String drive) {
    try {
        File file = File.createTempFile("realhowto",".vbs");
        file.deleteOnExit();
        FileWriter fw = new FileWriter(file);
        // to close a CD, we need eject two times!
        String vbs = "Set wmp = CreateObject(\"WMPlayer.OCX\") \n"
                   + "Set cd = wmp.cdromCollection.getByDriveSpecifier(\""
                   + drive + "\") \n"
                   + "cd.Eject \n "
                   + "cd.Eject ";
        fw.write(vbs);
        fw.close();
        Runtime.getRuntime().exec("wscript " + file.getPath()).waitFor();
        // thanks to TrueJavaProgammer for the waitFor() tip!
        // Runtime.getRuntime().exec("wscript "+ file.getPath());
        // Thread.sleep(2000);
    }
    catch(Exception e){
        e.printStackTrace();
    }
  }
}

As Coh3n said, to run this program you need a main method containing the code you want to run. It's just like the begin…end. in Pascal.

Also wanted to point out that you don't need to define a constructor if you're not gonna use it :p

Ok thanks, gonna make a fake-ass GUI of a mario game hacker and troll my freind

Ok now it's running but it does not open the Cd drive
