Abstract Class Compiling Problem

Question

This is my first time using the code tags, I apologize if I didn't do it right.
I can't seem to get the subclass to compile properly. I have defined an abstract class TemplateLoginCommand that encapsulates all of the login functionality. I have defined two abstract classes success and failure that should hold the code to forward the app to the right page on success, or handle any errors on login. I keep getting the following error message when I try to compile KlLoginCommand:
I am removing the package info so my boss doesn't flip
../command/KlLoginCommand.java [17:1] ../command.KlLoginCommand should be declared abstract; it does not define failure() in ../.command.TemplateLoginCommand
public class KlLoginCommand extends TemplateLoginCommand
^
1 error
Can anyone see what I am doing wrong here. I don't have a lot of experience with abstract classess/methods. Thanks
public abstract class TemplateLoginCommand extends PageVerificationCommand implements Constants
    // Required Form Fields
    public static final String[] REQUIRED_FIELDS = {USERNAME, PASSWORD};
    // Abstract Methods Must Be Subclasses
    abstract void success(UserEntity entity);
    abstract void failure();
    /** Creates new TemplateLoginCommand */
    public TemplateLoginCommand()
        super();
    public TemplateLoginCommand(String childDirectory)
        super(childDirectory);
    public void destroy(Map map) throws Exception
        super.destroy(map);
        // Validate
        if (verifyFields(REQUIRED_FIELDS, map))
            // Attempt login
            try
                String username = (String) map.get(USERNAME);
                String password = (String) map.get(PASSWORD);
                UserEntity user = UserEntity.login(username, password);
                // Forward to rolemenu
                success(user);
                return;
            catch( SQLException sqle )
                failure();
                return;
        else
            failure();
            return;
public final class KlLoginCommand extends TemplateLoginCommand
    /** Creates a new instance of KlLoginCommand */
    public KlLoginCommand()
    protected void failure()
    protected void success(UserEntity entity)
}

Hi,
Try making the methods
// Abstract Methods Must Be Subclasses
abstract void success(UserEntity entity);
abstract void failure();
protected.
