我是jb9+websphere,想用JNDI访问mysql  
 在http://localhost:9090/admin我配置如下  
 在jdbc提供程序里设置  
 类路径:D:mysqldrivermysql-connector-java-3.0.11-stable-bin.jar  
 实现类名为:com.mysql.jdbc.Driver  
 然后在数据源设置:  
 名称:DataSource  
 JNDI:jdbc/DataSource  
 最后在定制属性增加(这地方我删增了好多次,就是没效果):  
 databaseName--info  
 user-root  
 password--blue  
 url--jdbc:mysql://localhost/info  
 portNumber--3306  
 ConnectionURL--jdbc:mysql://localhost/info  
 使用连接代码如下  
 private   final   static   String   JNDI="jdbc/DataSource";  
 InitialContext   ctx=new   InitialContext();  
 DataSource   source=(DataSource)ctx.lookup(JNDI);  
 conn   =   source.getConnection();  
 结果source不为空,但是conn出现错误如下:  
 我不知道哪里错了,从昨天一直调到今天,websphere控制台打印功能又非常弱(system.out看不到出错信息,真是郁闷!)  
 实在不知道该怎么处理,恳请大虾指导一下,非常感谢!  
 java.sql.SQLException:   DSRA9002E:   ResourceException   带有错误代码   null:
