这篇文章给大家分享的是有关 websphere 与 mysql 连接的示例分析的内容。丸趣 TV 小编觉得挺实用的,因此分享给大家做个参考,一起跟随丸趣 TV 小编过来看看吧。
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!
