使用eclipse通过jboss开发简单的ejb应用（jboss7.x & ejb3.x）

package com.ilucky.ejb.service; import java.util.Random; import javax.ejb.Stateless; @Stateless public class HelloWorldBean implements HelloWorld { public HelloWorldBean() { } public static void main(String[] args) { HelloWorldBean hw = new HelloWorldBean(); try { hw.sayHello(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } /** * TODO: 是否需要操作数据库 * @throws Exception */ public String sayHello() { // try { Random r = new Random(); int i = r.nextInt(10); System.out.println("=============EJB Client comming=================(i % 3）=" + (i % 3)); if(i % 3 == 0) { int j = 0; //try { //throw new Exception("测试"); System.out.println("========> zero " + i/j); } // } catch (Exception e) { // e.printStackTrace(); // } // // } // } catch (Exception e) { // e.printStackTrace(); // System.out.println("-----------------------------END-------------------------------"); // System.out.println(e.toString()); // } return "Hello World !!!"; } } /** 15:39:26,980 ERROR [stderr] (EJB default -
