2.1安装和配置Jboss4.2
2.1.1Jboss下载网址
http://www.jboss.org
2.1.2JBoss简介
JBoss是全世界开发者共同努力的成果，一个基于J2EE的开放源代码的应用服务器。
因为JBoss代码遵循LGPL许可，可以在任何商业应用中免费使用它，而不用支付费用。
2006年,Jboss公司被Redhat公司收购。
JBoss 是一个管理EJB的容器和服务器，支持EJB 1.1、EJB 2.0和EJB3.0的规范。
但JBoss核心服务不包括支持servlet/JSP的WEB容器，一般与Tomcat或Jetty绑定使用。

2.1.3Jboss目录简介
/bin[启动和关闭Jboss的脚本]
/Client[Jboss客户端所需要的jar库]
/Docs[配置文件的样例,典型如数据库配置]
/lib[JBoss启动时所用到的java库，不把你工程的jar放在此处]
/server[多种Jboss配置]
/server/deault[默认配置]
/server/deault/conf[Jboss默认配置文件]
/server/deault/data[Jboss数据库文件如JbossMQ]
/server/deault/deploy[Jboss热部署目录.任何文件(jar,war,ear,xml)可以在不关闭Jboss服务的情况下部署]
/server/deault/lib[Jboss在启动缺省配置时加载的java库]
/server/deault/log[Jboss在启动缺省配置生成的日记文件]
/server/deault/tmp[Jboss在启动缺省配置生成的临时文件]

2.1.4Jboss配置文件
servr/config-name/conf目录
jacorb.properies[Jboss IIOP配置文件]
jbossmq-state.xml[JbossMQ(JMS实现)用户配置文件]
Jboss-service.xml[在启动时应该开启的jboss服务]
log4j.xml[log4J日志配置]
login-config.xml[安全配置]

2.1.5Jboss环境设置
格式如下:
Unix/Linux:
$export JAVA_HOME="JAVA JDK路径 "
$export JBOSS_HOME="JBOSS路径"
windows:
set JAVA_HOME="JAVA JDK路径 "
set JBOSS_HOME="JBOSS路径"

假如电脑是XP,jdk,jre,jboss安装位置如下:
jre="C:/Program Files/Java/jre6/"
jdk="C:/Program Files/Java/jdk1.6.0_19"
jboss="C:/jboss-4.2.2.GA"
则设置如下:
命令行xxx.cmd
set JAVA_HOME ="C:/Program Files/Java/jdk1.6.0_19"
set JBOSS_HOME="C:/jboss-4.2.2.GA"
set PATH="C:/Program Files/Java/jre6/bin";%PATH%
或者直接在电脑的环境变量添加
JAVA_HOME ="C:/Program Files/Java/jdk1.6.0_19"
JBOSS_HOME="C:/jboss-4.2.2.GA"
PATH="C:/Program Files/Java/jre6/bin";

/************************************************************************/
2.2配置数据源
Jboss配置oracle 10g
2.2.1复制oracle-ds.xml并配置它
//复制oracle-ds.xml
从C:/jboss-4.2.2.GA/docs/examples/jca目录选择oracle-ds.xml复制到
C:/jboss-4.2.2.GA/server/default/deploy
//修改oracle-ds.xml
把下面几个选项(jndi-name,connection-url,user-name,user-name,password)
修改成你自己的oracle 9i/10g环境

<jndi-name>OracleDS</jndi-name>
<connection-url>jdbc:oracle:thin:@youroraclehost:1521:yoursid</connection-url>
<user-name>x</user-name>
<password>y</password>
2.2.2复制oracle jar文件到Jboss部署目录
把oracle下面的ojdbc14.jar复制到C:/jboss-4.2.2.GA/server/default/lib
并启动Jboss,启动方法如下:
在windows下cmd进入命令行,
cd C:/jboss-4.2.2.GA/bin
run -b 0.0.0.0
Jboss在windows平台开始启动!

2.2.3验证数据源是否配置OK?
启动Jboss服务,进入http://localhost:8080/jmx-console/
选择service=JNDIView,找到List of MBean operations:下面的按钮Invoke
在java: Namespace节如果找到+- OracleDS (class: org.jboss.resource.adapter.jdbc.WrapperDataSource)
,说明Jboss已经连接到oracle数据库

/************************************************************************/
3.1EJB工程配置

3.1.1在myEclipse建立oracle数据源
打开DB Browser
在database Driver配置好数据源
Drive template:选择Oracle (Thin driver)
Drive name=oracle10g//自己定义一个名称
Connection URL/User name:/Password和oracle-ds.xml的配置一样
Driver JARs列表
add JARS把ojbc14.jar添加进来，
Test Driver测试成功则配置完毕.

3.1.2建立EJB工程
File->new-Ejb project
Project name="ejbSample"
J2EE Specification level选择Java EE 5.0 -EJB3
Persistence configuration打勾
配置JPA Persistence
Persistence Unit name=ejbSamplePU
JNDI Data Source=OracleDS //它和java: Namespace下面的+- OracleDS必须一致
Design-time Persistence Tools Configuration
Driver:选择在DB Browser配置好的名称
Catalog/Schema:选择一个oracle空间

/************************************************************************/
3.2persistence.xml配置
把系统生成persistence.xml配置完善它们
把上面的?换成自己的oracle 10g开发环境
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.3实体类
建立表的实体包entityBean,名称你也可以自己定
快速方法是用DB Browser生成实体类
[方法:右击b_customer_basic->EJB3 Reverse Enginerring...]
EJB3 Generation生成器
Java Src folder:定位到/ejbSample/src
Java package:定位到entityBean
Entity Bean Generation打勾,
其它不选择，直接点finish!
在entityBean包下6个表类共生成10个类
/entityBean
BCustomerBasic.java [对应表B_CUSTOMER_BASIC]
BCustomerPort.java  [对应表B_CUSTOMER_PORT]
BCustomerPortId.java[对应表B_CUSTOMER_PORT]
SSpNumber.java        [对应表S_SP_NUMBER]
SSpMaster.java      [对应表S_SP_MASTER]
SSpMasterId.java    [对应表S_SP_MASTER]
SSpDetail.java      [对应表S_SP_DETAIL]
SSpDetailId.java    [对应表S_SP_DETAIL]
VSpOcShipdate.java  [对应视图V_SP_OC_SHIPDATE]
VSpOcShipdateID.java[对应视图V_SP_OC_SHIPDATE]

/************************************************************************/
3.4工具类
建立公共使用包publicUtility
/publicUtility
在下面建立一个日记类LogUtil.java

public class LogUtil {
   
    private static final Logger logger;
   
    static {

4.1Web工程配置
新建立一个web工程，名字输入webSample,完成以后
配置web的Java build path(添加ejb工程和导入jboss客户jar文件)
4.1.1添加ejb工程ejbSample.jar到webSample工程
webSample右击->Properties->Java build path->Projects->add->选择ejbSample.jar
4.1.2导入jboss客户jar文件到web工程
jbossall-clinet.jar
jboss-remoting.jar
jboss-xml-binding.jar
jnpserver.jar
从jboss目录里面找到上面jar文件，然后把它们添加到web工程的Libraries清单!
添加方法：

4.2页面服务接口与实现
/*
用敏捷开发第5个原则
5.ISP接口隔离原则[适用于类的接口]
  不应该强迫客户程序依赖于它们不用的方法.
  接口属于客户,不属于它所在的类层次结构.
  详细说明:
  分离客户就是分离接口.分离接口有2种方法:委托和多重继承
  接口隔离原则是用来处理胖接口所具有的缺点.
  如果类接口不是内聚的,就表示该类的接口是胖的,需要减肥.
  减肥的原则是接口分成多组方法,每一组方法都服务于一组不同的客户程序!
  客户程序面对的就是多个具有内聚接口的抽象基类.
