JBoss配置mySQL數據源

說明：雖然此方法介紹的是如何在JBoss下配置mySQL數據源，其實按此方法，亦可配置Oracle數據源。

唯一的不同，就是配置Oracle數據源時，需要配置修改的文件名是oracle-ds.xml。

在jboss-4.2.2.GA/server/default/deploy下，新建一個mysql-ds.xml文件 (簡便的方法，是從jboss-4.2.2.GA/docs/examples/jca文件夾下複製並修改mysql-ds.xml文件)，大致修改至如下內容： 

<?xml version="1.0" encoding="UTF-8"?>

<!-- $Id: mysql-ds.xml,v 1.3.2.1 2004/12/01 11:46:00 schrouf Exp $ -->

<!--  Datasource config for MySQL using 3.0.9 available from:

http://www.mysql.com/downloads/api-jdbc-stable.html

-->

    <connection-url>jdbc:mysql://localhost:3306/test</connection-url>

    <!-- sql to call when connection is created

    <new-connection-sql>some arbitrary sql</new-connection-sql>

      -->

    <!-- sql to call on an existing pooled connection when it is obtained from pool 

    <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>

      -->

    <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->

    <metadata>

       <type-mapping>mySQL</type-mapping>

    </metadata>

  </local-tx-datasource>
