如何在JBOSS Server上发布EJB

<script type="text/javascript">google_ad_client = "pub-8800625213955058";/* 336x280, 创建于 07-11-21 */google_ad_slot = "0989131976";google_ad_width = 336;google_ad_height = 280;//</script><script type="text/javascript"src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>--------------------------------------------------------------------------------1.准备文件 需要的软件:JDK1.3(for WIN) ,J2EE_1_2_1_SDK,JBoss2.0(www.jboss.org) 需要的文档:J2EE_1_2_1_SDK_DOC,Devguide1_2_1 2.准备环境 安装JDK1.3(支持JBOSS),装完后检查一下环境变量,可以编译运行一个小程序试一下. 安装JBOSS2.0,完成后运行bin/run.bat试一下.JNDI 端口是1099,WEB端口是8080,可以用浏览器试一下,1099端口会返回一段乱码,8080端口返回空. 3.编译和打包 按照JavaTM 2 Enterprise Edition Developer´s Guide (v1.2.1)的Getting Started章中说的编译例子程序 ConverterEJB,然后用Deploy Tool打包生成 ConverterApp.ear. 用jar -xvf ConverterApp.ear 从中抽取 ejb-jar-ic.jar 这是打包好的和Bean有关的三个文件和工具生成meta-info/*.xml文件(所谓的deployment descriptor). 然后运行JBoss的Deploy Tool打开ejb-jar-ic.jar,设置JNDI Name为MyConverter.然后保存.(该工具会自动生成JBoss的Deployment descriptor) 在把ejb-jar-ic.jar拷到jboss/deploy目录下,jboss会自动发布该Bean.. 4.运行客户端程序测试 按照JBoss的教学文档,修改 ConverterClient.java为 import javax.naming.*; import java.util.Hashtable; import javax.rmi.PortableRemoteObject; import java.util.Properties; import java.io.FileInputStream; import javax.rmi.PortableRemoteObject; import Converter; import ConverterHome; public class ConverterClient { public static void main(String[] args) { try { Properties props = new Properties(); Properties sysProps = System.getProperties(); try { props.load (new FileInputStream ("test.properties")); sysProps.putAll(props); } catch (Exception e) { System.err.println ("Can´t read `test.proprties´"); System.exit (-1); } System.setProperties (sysProps); Context initial = new InitialContext(); Object objref = initial.lookup("MyConverter"); ConverterHome home = (ConverterHome)PortableRemoteObject.narrow(objref, ConverterHome.class); Converter currencyConverter = home.create(); double amount = currencyConverter.dollarToYen(200.00); System.out.println(String.valueOf(amount)); amount = currencyConverter.yenToEuro(200.00); System.out.println(String.valueOf(amount)); } catch (Exception ex) { System.err.println("Caught an unexpected exception!"); ex.printStackTrace(); } } } test.properties文件内容如下 java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.provider.url=xxx.xxx.xxx.xxx:1099 (写上JBoss所在机器的IP) 然后运行CompileClient.bat和TestClient.bat,就可以享受成功的喜悦了.
