EJB3已經變得很簡單了，在這記上一筆。
關於EJB3,可參閱：http://www.foshanshop.Net/
服務器選擇Jboss。客戶端需要導入Jboss/client/jbossall-clIEnt.jar才能調用發布在Jboss中的EJB。
代碼：
HelloBeanLocal.Java
vIEw plaincopy to clipboardprint?
package session;
import Javax.ejb.Local;

HelloBeanRemote.Java
vIEw plaincopy to clipboardprint?
package session;

public interface HelloBeanRemote {
public String sayHello(String name);

package session;
