一个helloworld的例子,以及讲明如何用ant去打包以及其脚本.

首先是程序

package com.liao;

public interface HelloWorld {
public String SayHello(String name);
}

package liao;

public interface HelloWorldLocal extends HelloWorld{

}

package com.liao.impl;

import com.liao.HelloWorld;
import com.liao.HelloWorldLocal;

import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;

@Stateless(mappedName="HelloWorldBean")
@Remote (HelloWorld.class)
@Local (HelloWorldLocal.class)
public class HelloWorldBean implements HelloWorld, HelloWorldLocal {

    public String SayHello(String name) {
        return name +"说：你好!?";
    }

}

web部分的测试jsp:
<%@ page contentType="text/html; charset=GBK"%>
<%@ page import="com.foshanshop.ejb3.*, javax.naming.*"%>
<%
try {
        InitialContext ctx = new InitialContext();
      HelloWorldLocal local = (HelloWorldLocal) ctx.lookup("java:comp/env/ejb/HelloWorldLocal");
      out.println(local.SayHello("test"));
} catch (Exception e) {
  out.println(e.getMessage());
}
%>

web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   <description>foshanshop ejb3.0 Sample</description>

<ejb-local-ref>
    <ejb-ref-name>ejb/HelloWorldLocal</ejb-ref-name>
    <ejb-ref-type>Session</ejb-ref-type>
    <local>com.foshanshop.ejb3.HelloWorldLocal</local>

    <ejb-link>HelloWorldBean</ejb-link>
</ejb-local-ref>
    <welcome-file-list>
      <welcome-file>Test.jsp</welcome-file>
</welcome-file-list>
</web-app>

当ejb模块和web一起打包成.ear时,要在meta-inf下放application.xml

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd"
             version="5">
<display-name>EJB3 Sample Application</display-name>
<module>
  <web>
   <web-uri>HelloWorld.war</web-uri>
   <context-root>HelloWorld</context-root>
  </web>
</module>
<module>
     <ejb>HelloWorld.jar</ejb>
</module>
</application>

ant的配置文件:

<?xml version="1.0"?>



<project name="WeblogicHelloWorld" default="ear" basedir="..">
<property name="app.dir" value="${basedir}/WeblogicHelloWorld" />
<property name="src.dir" value="${app.dir}/src" />
<property name="weblogic.home" value="C:/bea/wlserver_10.3" description="weblogic产品所在目录,本书安装在C:/bea/wlserver_10.3"/>
<property name="wls.username" value="weblogic" description="登录用户名,默认为weblogic"/>
<property name="wls.password" value="weblogic" description="登录密码,默认为weblogic"/>
<property name="wls.hostname" value="localhost" description="主机名称"/>
<property name="wls.port" value="7001" description="所在端口,默认为7001"/>
<property name="wls.server.name" value="examplesServer" description="weblogic中的目标服务器,默认为examplesServer"/>
<property name="build.dir" value="${app.dir}/build" />
<property name="build.classes.dir" value="${build.dir}/classes" />

<path id="build.classpath">
  <fileset dir="${basedir}/lib/javaee">
   <include name="*.jar" />
  </fileset>
  <fileset dir="${weblogic.home}/server/lib">
   <include name="weblogic.jar" />
  </fileset>
  <pathelement location="${build.classes.dir}" />
</path>

<taskdef name="wldeploy" classname="weblogic.ant.taskdefs.management.WLDeploy" classpathref="build.classpath"/>



<target name="prepare" depends="clean">
  <mkdir dir="${build.dir}" />
  <mkdir dir="${build.classes.dir}" />
</target>

<target name="compile" depends="prepare" description="编绎">
  <javac srcdir="${src.dir}" destdir="${build.classes.dir}" debug="on" deprecation="on" optimize="off" includes="com/**">
   <classpath refid="build.classpath" />
  </javac>
</target>

而如果用J2SE的测试文件:

package junit.test;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import org.junit.Test;

import com.liao.HelloWorld;
/**
* 执行该用例，你需要JDK1.6以上版本，并且需要把[weblogic home]/wlserver_10.3/server/lib/weblogic.jar加入到类路径下
* @author lihuoming
*
*/
public class HelloWorldTest {

@Test
public void testSayHello() {
  try {
    Properties props = new Properties();
    props.setProperty(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
    props.setProperty(Context.PROVIDER_URL, "t3://localhost:7001");
    InitialContext ctx = new InitialContext(props);
    HelloWorld remote = (HelloWorld) ctx.lookup("HelloWorldBean#"+ HelloWorld.class.getName());
    System.out.println(remote.SayHello("test"));
  } catch (NamingException e) {
   e.printStackTrace();
  }
}
