Weblogic7+mysql的配置问题！急，高分！

[pangolincn]

在配置weblogic7+mysql时，我按下面配置的，在完成最后面的步骤后，出现了下面的错误.请高手帮帮忙。看看错误出现在那里？高分相赠！！！
配置WLS7
假如WLS7安装在c:\bea下，进入c:\bea\weblogic700\bin目录，修改startWLS.cmd(注意首先修改这个
文件是因为有的文档上说修改c:\bea\user_projects\mydomain\下的startWeblogic.cmd，是不对的。）首先修
改这个文件是这时c:\bea\user_projects\mydomain\下的startWeblogic.cmd还没有产生，保证你不会改错。如
果是linux下修改startWLS.sh

找到set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\weblogic_sp.jar;
%WL_HOME%\server\lib\weblogic.jar;%CLASSPATH%
加上mysql.jar：成
set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%WL_HOME%\server\lib\weblogic_sp.jar;
%WL_HOME%\server\lib\weblogic.jar;path\mysql.jar;%CLASSPATH%

存档退出，在启动菜单上运行BEA Weblogic platform 7.0 -> domain configuration wizard有的就叫
configuration wizard。

1.Select a template:选择WLS Domain，Name默认的mydomain
2.Choose Server Type: 第一个
3.Specify directory for "mydomain" domain:C:\bea\user_projects\
4.value Administrative Server Info-Admin Server Name or IP 写机器的ip，这样保险，其它默认
5.Configure Managed Server: Server Name:默认为myserver
Server Listen Address:写机器的ip .其它默认
6.Create System UserName and Password:写用户名和密码,如:system:aaaaaa
7.Install Server as Windows Servic:这里问要不要在启动操作系统时启动，可根据自己的需用选择。
8.Install Domain in Windows Start Menu:这里问要不要在开始菜单添加快捷方式，建议是“Yes”.
这样在开始菜单中会出现EBA Weblogic Platform 7.0->User projects-my domain->Start Server

如果8选择了yes，现在就从开始->EBA Weblogic Platform 7.0->User projects-my domain->Start Server启动
等一会儿，启动结束后进入：http://localhost:7001/console如果找不到页面把localhost换成主机名或IP试试
如果不能进入检查上面的步骤，反正这里如果不能访问向下做了，死也要给我访问到这个页面。
输入刚才的用户名和密码(system:aaaaaa)进入。

在左边的目录树中选中Services->JDBC->Connection Pools，单击右侧的Configure a new JDBC Connection Pool.
输入以下信息：
Configuration->General页：
Name = Mysql Connection Pool
URL = jdbc:mysql://localhost:3306/ejbdb(注意ejbdb是我上面的例子字段，以下都会这样)
Driver classname = org.gjt.mm.mysql.Driver
Properties :
user=root
password=111111 这两行是Properties 的内容，就是name=value形式
单击Create建立连接池。
选择Targets->Server页：
将myserver(服务器名称)移至右侧的列表中，但击单击Apply
