Weblogic7.0连接池问题，急！100分-----

[wangzhi99]

我在配置weblogic7.0时，ConnectionPool和DataSource 都要在target选项中将你的Server选中，我新建一个连接池，当我将target中的myserver从左边移到右边，点击APPLY后，出现以下问题：

当我第二次APPLY，又没有异常
不知道为什么？？？

[wangzhi99]

来迟了，请见谅！我用的是Oracle数据库，在connection pools中apply时出错，在data sources中apply时同样出错 。

请问在classpath中要加什么驱动？
是不是class12.jar文件，如果是，那么加在weblogic的什么目录下？？
这是我的connection pools的设置：
name Oracle Server Connection Pool
url jdbc:oracle:thin:@localhost:orc1
drive classname oracle.jdbc.driver.OracleDriver
user=wangzhi
Password=12345678

[baitianhai]

你应该编辑 你启动 weblogic的 startWebLogic.cmd 脚本,把class12.jar添加到其中的classpath设定中去

[kexsong]

那是你的connection pools中的general页的填写有错误啊，检查url、drive name、user和password吧

[owenyang]

除了楼上说的为，你用的是什么数据库？有没有相关的驱动程序？
到底是connection pools在apply时出错还是data sources在apply时出错？

[peppi]

什么数据库啊?

[313fxq]

可能是以上各位说的某些中间环节出现了错误！

[sandsworlf]

我用的是oracle8i，
和楼主也是出的同样问题。
请指点迷径

[westfailure]

如果你用的是SQL Server2000 的JDBC，你要在weblogic的startwbl.cmd的classpath加入jdbc的三个jar文件方可。

[wangzhi99]

请问class12.jar加到weblogic的具体什么位置？
我没有找到它的classpath设置的位置

[松耦合紧内聚]

help you up

[wangzhi99]

请问加到具体什么位置？我没有找到它的classpath设置的位置

[owenyang]

有没有class12.zip或者class12.jar?
如果你的weblogic装在c盘，那么在C:\bea\weblogic700\server\ext\jdbc\oracle\817目录下应该有classes12.zip
如果你先建立了mydomain(你自己的domain),那么应该在C:\bea\user_projects\mydomain目录下有startWebLogic.cmd，
把class12.zip添加到其中的classpath设定中去

兄弟解决了吗？我也是差不多的问题，我的错误是：

后面还有很多错误

请问大虾们这是怎么回事？如何解决，我可以另外给分的
