Jboss3.0-Tomcat4.03的数据库的配置(以Oracle为例)
一、 请将classes12.zip加入classpath中去。
二、请参况hsqldb-service.xml文件编写Oracledb-service.xml文件
请打开server\default\deploy目录下的hsqldb-service.xml文件，这就是一个Jboss3.0_Tomcat4.03下实现数据库连接的例子，它是连接hsql数据库的它的内容如下：
<?xml version="1.0" encoding="UTF-8"?>

Update your login-conf.xml, here is an example for a
ConfiguredIdentityLoginModule:

<application-policy name = "HsqlDbRealm">

NOTE: the application-policy name attribute must match
SecurityDomainJndiName, and the

请大家对比两个文件的不同之外，很容易写出其它数据库的存取服务了，主要的是下面这个部分
<mbean code="org.jboss.resource.connectionmanager.RARDeployment" name="jboss.jca:service=LocalTxDS,name=oracleDS">

<attribute name="JndiName">OracleDS</attribute><!--这个地方是JNDI的名字在ejb或jsp中调用的是java:/OracleDS - ->
<attribute name="ManagedConnectionFactoryProperties">
<properties>
<config-property name="ConnectionURL" type="java.lang.String">jdbc:oracle:thin:@cuipeng:1521:ora8</config-property>
<config-property name="DriverClass" type="java.lang.String">oracle.jdbc.driver.OracleDriver</config-property>
<config-property name="UserName" type="java.lang.String">system</config-property>
<config-property name="Password" type="java.lang.String">manager</config-property>
</properties>
</attribute>
<depends optional-attribute-name="OldRarDeployment">jboss.jca:service=RARDeployment,name=JBoss LocalTransaction JDBC Wrapper</depends>
</mbean>
还有就是各个部分的名字了name=oracleDS
三、测试数据的连接列子(我用的是jsp)
你必需要编写.war或.ear包来测试一个简易的做法就是：
一、 在deploy目录下建立oracle-test.war目录。
二、在oracle-test.war目录下建立WEB-INF目录，其中有两个文件
jboss-web.xml和web.xml
内容分别是
jboss-web.xml内容是
<jboss-web>
</jboss-web>
web.xml内容是
<?xml version="1.0"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
</web-app>
三、在oracle-test.war目录下建立新文件index.jsp其内容是
<%@page contentType="text/html"%>
<%@ page import="java.sql.*, javax.sql.DataSource, javax.naming.InitialContext" %>

<h3>Test Oracle DB</h3>

<%


InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:/OracleDS"); //注意这里哦和前面对应
Connection conn = ds.getConnection();


Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM TAB");


while ( rs.next() ) {
out.println( rs.getString("TNAME") + "<br>");
}

conn.close();

%>
　四、请访问http://localhost:8080/oracle-test
一切都测试ＯＫ的，如果有什么不对的地方请指哦，我也是学习的。这是一个快速的配置方法,在过一些时间我会把每个属性表示什么给大家说说.
