YAML Support for Java

Question

I have a java program written which has to read a configuration file written using YAML (config.yml)
I downloaded the yamlbeans-1.0.jar* from http://yamlbeans.sourceforge.net/ which has the YamlReader class I am using in my java program. And I then copied the YamlReader.class file to the folder where I have my Testing.java program.
Please find my java and config.yml files below.
//JAVA FILE
class Testing
public static void main(String args[]) throws Exception
     YamlReader reader = new YamlReader(new FileReader("config.yml"));
     Object object = reader.read();
     System.out.println(object);
     Map map = (Map)object;
     System.out.println(map.get("NAME"));
//YAML file
NAME: mail.foobar.net
EMAIL_ADDRESS: [email protected]
AGE: 15
when I try to compile the java file, I get the following error.
C:\Users\David\Desktop\webstat\Testing.java:11: cannot access YamlReader
bad class file: .\YamlReader.class
class file contains wrong class: net.sourceforge.yamlbeans.YamlReader
Please remove or make sure it appears in the correct subdirectory of the classpath.
     YamlReader reader = new YamlReader(new FileReader("config.yml"));
     ^
1 error
Tool completed with exit code 1
Can some one please suggest me what has to be done to get YamlReader accessible in my program.
Thanks!

First, and most importantly, you didn't even give an example that can compile. But it is Friday and I'm in a decent mood. So I download the jar file. These are the exact steps I used:
mkdir yamltest
cd yamltest
cp ~yamlbeans-1.0.jar .
javac -cp yamlbeans-1.0.jar Testing.java
java -cp .:yamlbeans-1.0.jar TestingMy compilable program is:
import net.sourceforge.yamlbeans.YamlReader;
import java.io.FileReader;
import java.util.Map;
public class Testing {
    public static void main( String[] argv ) {
        try {
            YamlReader reader = new YamlReader(new FileReader("config.yml"));
            Object object = reader.read();
            System.out.println(object);
            Map map = (Map)object;
            System.out.println(map.get("NAME"));
        catch( Exception e ) {
            e.printStackTrace();
}The config.yml is like you show.
The output is:
$ java -cp .:yamlbeans-1.0.jar Testing
{NAME=mail.foobar.net, AGE=15, EMAIL_ADDRESS=[email protected]}
mail.foobar.netYou're not setting your classpath correctly.
