1、下载和安装
<1>下载可以到www.jboss.org下载，我下的是jboss3.2.1。并且不是那个和tomcat整合的版本。
<2>安装方法就是将文件解压到硬盘的某个目录下（例如：我的解到 d:\jboss-3.2.1)。
2、配置
<1>首先必须安装jdk。jboss不像weblogic自带java标准开发包。我安装的是1.4 安装目录是C:\j2sdk1.4.0 。
<2>设置环境变量
<<1>>JAVA_HOME设置为JDK的安装目录（例如：我的为C:\j2sdk1.4.0）
<<2>>classpath的设置：看看我的，大家就知道该包含哪些包了
C:\j2sdk1.4.0\lib\tools.jar;
D:\jboss-3.2.1\server\default\lib\javax.servlet.jar;
D:\jboss-3.2.1\server\default\lib\jboss-j2ee.jar;
.;
D:\jboss-3.2.1\client\jbossall-client.jar;
D:\jboss-3.2.1\client\jnet.jar;
D:\jboss-3.2.1\client\log4j.jar;
3、运行
进入jboss3.2.1的bin目录，执行run.bat就可以了。看到出现
00:59:26,978 INFO [Server] JBoss (MX MicroKernel) [3.2.1 (build: CVSTag=JBoss_3
_2_1 date=200305041533)] Started in 17s:595ms
这样的提示信息就说明启动成功，测试方法如下
http://localhost:8080/jmx-console 你将看到jmx agent view
4、使用
<1>html,jsp测试
jboss的默认web目录是在jboss-3.2.1\server\default\deploy下面。下面就介绍测试jsp,servlet,ejb的方法：
对于测试首先在deploy下建立一个test.war文件夹，然后将html,jsp文件都可以放到这里进行测试
例如建立一test.jsp如下：
<%@ page language="java" %>
<%@ page contentType="text/html;charset=gb2312" %>
<%@ page import="java.util.*" %>
<%=new Date().toLocalString()%>
通过http://localhost:8080/test/test.jsp调用就可得到当前日期时间。
<2>设置sql server2000的数据源然后在jsp中操调用操作数据库
<<1>>下载安装sql server2000的jdbc驱动（微软提供）
<<2>>将mssqlserver,msbase,msutil三个jar文件复制到jboss-3.2.1\server\default\lib目录下面
<<3>>将jboss-3.2.1\docs\examples\jca\mssql-ds.xml复制一份到jboss-3.2.1\server\default\deploy下面
部分修改如下：
<datasources>
<local-tx-datasource>
<jndi-name>ds</jndi-name>
<connection-url>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Northwind</connection-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<user-name>sa</user-name>
<password></password>
</local-tx-datasource>
</datasources>
上面的配置就是用ds作为数据源的名称，用不带密码的sa用户连接sql server的样板数据库northwind。你可以作适当的修改。
<<4>>配置完成后，用如下testSql.jsp文件测试数据库操作
<%@ page language="java" %>
<%@ page import="javax.naming.*" %>
<%@ page import="javax.sql.*" %>
<%@ page import="java.sql.*" %>
<%!
javax.sql.DataSource ds;
%>
<%
try {
Context ctx = new InitialContext();
ds = (javax.sql.DataSource)ctx.lookup("java:/ds");
} catch (Exception e) {
out.println("erro when connect to java naming api");
}
Connection conn = ds.getConnection();
Statement st = conn.createStatement();
String sqlStr = "select * from categories";
ResultSet rs = st.executeQuery(sqlStr);
while ( rs.next() ) {
out.println(rs.getString("categoryName")+"<br>");
}
rs.close();
st.close();
conn.close();
%>
将输出categories表的每条记录的categoryName,值得注意的是在mssql-ds.xml设置的jndi-name是ds,而真正的绑定是
java:/ds。
<3> servlet的配置测试
<<1>>编写并编译如下的简单servlet
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("");
out.println("Hello World");
out.println("<p><p><p><p><div align='right'>author's email:[email protected]</div>");
}
}
<<2>>在test.war文件夹下建立一个WEB-INF目录，里面再建立一个classes目录和web.xml文件目录结构如下：
[test.war]
[WEB-INF]
[classes]
web.xml
将编译成功的HelloWorld.class放置到classes目录下，web.xml内容如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2.2.dtd">
<web-app>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
</web-app>
通过调用http://localhost:8080/test/HelloWorld 就可以看到hello world的输出
<4>session bean的测试(Hello)
这是一个简单的stateless session bean的测试
<<1>>Hello.java
import java.rmi.RemoteException;
import javax.ejb.EJBObject;
public interface Hello extends javax.ejb.EJBObject {
public String hello() throws java.rmi.RemoteException;
}
<<2>>HelloHome.java
import java.rmi.RemoteException;
public interface HelloHome extends javax.ejb.EJBHome {
Hello create() throws java.rmi.RemoteException,javax.ejb.CreateException;
}
<<3>>HelloBean.java
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class HelloBean implements javax.ejb.SessionBean {
private SessionContext ctx;
public void ejbCreate() {
System.out.println("ejbCreate()");
}
public void ejbRemove() {
System.out.println("ejbRemove()");
}
public void ejbActivate() {
System.out.println("ejbActivate()");
}
public void ejbPassivate() {
System.out.println("ejbPassivate()");
}
public void setSessionContext(javax.ejb.SessionContext ctx) {
his.ctx = ctx;
}
public String hello() {
System.out.println("hello()");
return "hello,world";
}
}
<<4>>ejb-jar.xml
<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC
'-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN'
'http://java.sun.com/dtd/ejb-jar_2_0.dtd'>
<ejb-jar>
<enterprise-beans>
<session>
<ejb-name>Hello</ejb-name>
<home>HelloHome</home>
<remote>Hello</remote>

<enterprise-beans>
<session>
<ejb-name>Hello</ejb-name>
<jndi-name>HelloEJB</jndi-name>
</session>
</enterprise-beans>
</jboss>
<<6>>
编译3个.java文件后按照以下路径存放文件（假设放到d:\sessionEjb下面）
d:\sessionEjb\Hello.class
d:\sessionEjb\HelloBean.class
d:\sessionEjb\HelloHome.class
d:\sessionEjb\META-INF\ejb-jar.xml
d:\sessionEjb\META-INF\jboss.xml
然后打包d:\sessionEjb\jar cvf helloejb.jar *.*，打包后将helloejb.jar放到deploy目录下面,会在控制台看到如下输出
11:35:30,815 INFO [EjbModule] Creating
11:35:30,825 INFO [EjbModule] Deploying Hello

});
setTitle("EJBClient");
setSize(300,200);
Container contentPane = getContentPane();
area = new JTextArea(6,20);
subButton = new JButton("Say hello to EJB");
subButton.setActionCommand("sya");
subButton.addActionListener(this);
contentPane.add(area,"Center");
contentPane.add(subButton,"South");
}
public void actionPerformed(ActionEvent e) {
if ( e.getActionCommand().equals("sya") ) {
ejbSays = getEJBInfo();
area.append(ejbSays + "\n");
}
}
public String getEJBInfo() {
try {
Context jndiContext = getInitialContext();
Object ref = jndiContext.lookup("HelloEJB");
HelloHome home = (HelloHome)PortableRemoteObject.narrow(ref,HelloHome.class);
Hello hw= home.create();
ejbSays = hw.hello();
} catch (java.rmi.RemoteException e) {
e.printStackTrace();
} catch ( Throwable t ) {
t.printStackTrace();
} finally {
}
return ejbSays;
}
public static Context getInitialContext() throws Exception {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,

p.put(Context.PROVIDER_URL, "localhost:1099");
return new InitialContext(p);
}

JFrame win = new HelloWorldClient();
win.pack();
win.setVisible(true);
}
private String ejbSays="";
private JTextField info;
private JButton subButton;
private JTextArea area;
}
作了一个简单的gui,主要注意的是getInitalContext()方法jboss的连接参数的设置和getEJBInfo()方法对ejb的调用
将编译好的HelloWorldClient.class,HelloWorldClient$1.class,放置到d:\sessionbean目录下（如果放到别的地方，确定可以
通过路径找到HelloBean,HelloHome,Hello类
d:\sessionbean\java HelloWorldClient
点按钮就会返回hello world(做gui是为了复习一下以前的知识)
<5>cmp的测试
此cmp继续使用上面的数据源对应的northwind数据库，要在其中建一个表cd。

<<7>>编译部署
编译3个.java文件，按照下面的目录结构存放（假设放在d:\cmpbean下面）
d:\cmpbean\CD.class
d:\cmpbean\CDHome.class
d:\cmpbean\CDBean.class
d:\cmpbean\META-INF\ejb-jar.xml
d:\cmpbean\META-INF\jboss.xml
d:\cmpbean\META-INF\jbosscmp-jdbc.xml
打包：d:\cmpbean\jar cvf cdejb.jar *.*
将cdejb.jar复制到deploy目录下
<<8>>客户端代码测试

import javax.naming.Context;
import javax.naming.NamingException;
import javax.ejb.CreateException;
import java.rmi.RemoteException;
import javax.rmi.PortableRemoteObject;
import java.util.Properties;

p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL, "localhost:1099");
return new InitialContext(p);
}
public static void main(String[] args) {
try {
Context jndiContext = getInitialContext();
Object ref= jndiContext.lookup("ejb/cdbean");
CDHome home = (CDHome)PortableRemoteObject.narrow(ref,CDHome.class);
home.create(new Integer(100),"Bohn jove","rock and roll","rock","a good type");
home.create(new Integer(200),"黑宝","rock","rock","roll star");
home.create(new Integer(300),"mike jackson","sssss","iiop","none");
Collection c = home.findByType("rock");
Iterator i = c.iterator();
while ( i.hasNext() ) {
String ss = ( (CD)javax.rmi.PortableRemoteObject.narrow(i.next(),CD.class)).getNotes();
System.out.println(ss);
}
} catch (java.rmi.RemoteException e) {
e.printStackTrace();
} catch (Throwable t) {
t.printStackTrace();
} finally {
}
}
}
请确保通过类路径可以找到CD.class,CDHome.Class.
执行java CDclient 将看到如下输出：
D:\cmpbean\>java CDClient
a good type
roll star
D:\cmpbean\>
5、结束语
首先我也是个初学者，自己在csdn上多次提问有关jboss的问题，却所得到回答甚少。
而且搜索了很久也找不到相应的文档可以了解jboss3.2的使用。
为此希望写此文档为初学者提供一点帮助，错误的地方还请指正。
另外、对于jboss3.2 mssql-xa-ds.xml的设置以及连接池的
使用方法，有谁弄过，请告诉我，不胜感激。 email: [email protected]
