1.下载mysql-connector-java-5.1.25.jar包（见附件)
2.解压，将mysql-connector-java-5.1.25-bin.jar拷贝到%jboss_home%/modules/com/mysql/main目录下（目录不存在就新建），在同目录下新建module.xml文件，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.25-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.servlet.api" optional="true"/>
</dependencies>
</module>
3.修改%jboss_home%/standalone/configuration/standalone.xml文件，将datasources节点修改为：
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>
<datasource jndi-name="java:jboss/datasources/jboss_webDS" pool-name="MySqlDS">
<connection-url>jdbc:mysql://113.106.92.109:3306/test?useUnicode=true</connection-url>
<driver>com.mysql</driver>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>100</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>root</user-name>
<password>broadengate</password>
</security>
<statement>
<prepared-statement-cache-size>32</prepared-statement-cache-size>
<share-prepared-statements>true</share-prepared-statements>
</statement>
</datasource>
<drivers>
<driver name="com.mysql" module="com.mysql">
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
