這篇文章給大家分享的是有關(guān)websphere與MySQL連接的示例分析的內(nèi)容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。

我是jb9+websphere,想用JNDI訪問mysql
在http://localhost:9090/admin我配置如下
在jdbc提供程序里設(shè)置
類路徑:D:mysqldrivermysql-connector-java-3.0.11-stable-bin.jar
實現(xiàn)類名為:com.mysql.jdbc.Driver
然后在數(shù)據(jù)源設(shè)置:
名稱:DataSource
JNDI:jdbc/DataSource
最后在定制屬性增加(這地方我刪增了好多次,就是沒效果):
databaseName--info
user-root
password--blue
url--jdbc:mysql://localhost/info
portNumber--3306
ConnectionURL--jdbc:mysql://localhost/info
使用連接代碼如下
private final static String JNDI="jdbc/DataSource";
InitialContext ctx=new InitialContext();
DataSource source=(DataSource)ctx.lookup(JNDI);
conn = source.getConnection();
結(jié)果source不為空,但是conn出現(xiàn)錯誤如下:
我不知道哪里錯了,從昨天一直調(diào)到今天,websphere控制臺打印功能又非常弱(system.out看不到出錯信息,真是郁悶!)
實在不知道該怎么處理,懇請大蝦指導(dǎo)一下,非常感謝!
