我的一些ejb的入门程序

package stateful;

import javax.annotation.PreDestroy;
import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.ejb.Stateless;

@Stateful
public class CountBean implements CountBeanLocal, CountBeanRemote {
	private int val;
	
	public CountBean() {
		System.out.println("CountBean's default constructor");
	}

	public int count() {
		// TODO Auto-generated method stub
		System.out.println("count()");
		return ++val;
	}

	public void set(int initVal) {
		// TODO Auto-generated method stub
		System.out.println("set()");
		val = initVal;
	}

	@Remove
	public void remove() {
		// TODO Auto-generated method stub
		System.out.println("remove()");
	}
	
	@PreDestroy
	public void cleanup(){
		System.out.println("cleanup()");
	}

}
