</local-tx-datasource></datasources>jboss4.2.1GA oracl配置1.在$JBOSS_HOME$\server\default\deploy下创建oracle-ds.xml，代码如下：<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<local-tx-datasource>
<jndi-name>jdbc/oracle</jndi-name>
<connection-url>jdbc:oracle:thin:@yourserver:1521:youroracleid</connection-url>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
<user-name>yourusername</user-name>
<password>yourpassword</password>
<max-pool-size>300</max-pool-size>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
</local-tx-datasource>
</datasources>2.在你的web工程下的WEB-INF下的web.xml文件中添加如下代码：<resource-ref>
<description>Oracle Connection</description>
<res-ref-name>jdbc/oracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>3.在你的web工程下的WEB-INF下新建一个jboss-web.xml文件，代码如下：<?xml version="1.0" encoding="ISO-8859-1"?>
<jboss-web>
<resource-ref>
<description>Oracle Connection</description>
<jndi-name>java:jdbc/oracle</jndi-name>
<res-ref-name>jdbc/oracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</jboss-web>4.在你的java代码里连接数据库那段代码修改如下： Connection con = null; DataSource datasource = null;
Context ctx = new InitialContext();
Context envCtx = (Context) ctx.lookup("java:comp/env");
datasource = (DataSource) envCtx.lookup("java:jdbc/oracle");
con = datasource.getConnection();这部分代码是连接jboss连接池的5.发布工程，重启jboss服务，大功告成。。
