使用Eclipse开发J2EE应用

核心提示： 通过File->New->Lomboz EJB Test Client Wizard打开一个对话框，按下图填写：完成以后，使用Eclipse开发J2EE应用(7)，在src目录下面生成了TestMyEJB.java，在其中的testBean方法中加入测试代码：System.out.p

通过File->New->Lomboz EJB Test Client Wizard打开一个对话框，按下图填写：

完成以后，在src目录下面生成了TestMyEJB.java，在其中的testBean方法中加入测试代码：

System.out.println(myBean.helloWorld());　

如果目前JBoss服务器已经启动，而且MyEJB模块已经部署的话，执行TestMyEJB，就会在Console窗口上显示出：

hehe,　I　can　deploy　EJB　by　Eclipse!　

四、总结

通过以上的介绍，我们了解到，Lomboz使Eclipse开发J2EE应用变得非常简便，而且Eclipse, Lomboz, JBoss这些工具都是免费和开放源码的项目，所以这样的组合对Java开发者来说更有吸引力。

对于开发复杂的J2EE应用来说，上面的介绍可能还不够全面，希望大家在做项目的过程中体会，再将总结出来的经验放到developerWorks上来分享。
