d:\eclispe2.1.3

d:\mysql4.0.16

mysql 用户名root 密码root

数据库tsb tsb数据库用户名tsb,密码tsb

mysql的mysql-2.0.14.jar也已经放到D:\jboss-3.2.5\server\default\lib

p;characterEncoding=GBK&autoReconnect=true</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>

我觉得你在web.xml中是不是需要指定对MySqlDS的资源引用呢?否则就可能会出现你的问题。

没看到说需要修改web.xml的文章阿

自己去设计一个分布式计算方案吧,就不会这么痛苦了。

将JBoss/DOCS/JCA下的mysql-ds.xml拷贝到server/default/deploy下,改写mysql-ds.xml,记住其中的JNDI名称,在程序中以java:/JNDI名称调用即可。

这是个基本问题。

应该多找些资料看一下。
