一.配置weblogic服务�?br />start menu->program->BEA Weblogic Platfrom 8.1->Configuration Wizard->Create a new Weblogic->next->next->next->(user password)next->(select jdk)next->(datasource)create
�?数据库驱动配�|?br />copy mysql-connector-java-3.1.11-bin.jar to %WL_HOME%\
在d:\SoftWare\BEA\user_projects\domains\datasource\startWebLogic.cmd的set CLASSPATH=部分加入%WL_HOME%\mysql-connector-java-3.1.11-bin.jar
�?配置数据库连接池
1.start menu->program->BEA Weblogic Platfrom 8.1->User Projects->datasource->Start Server
2.打开http://127.0.0.1:7001/console weblogic 12345678
3.datasource->服务->JDBC->�q�接�~�冲�?Connections Pools)->(配置新的JDBC�q�接�~�冲�?configure a new JDBC Connection Pools
4.Database Type 选择mysql驱动为org.gjt.mm.mysql.Driver
5.Continue
名称:MyJDBC Connection Pool
数据库名�U?datasource
��L��?127.0.0.1
端口:3306
数据库用户名:
密码:
��认密码:
5.Continue->Test Driver Configuration
6.Create and deploy
�?配置数据�?br />1.datasource->服务->JDBC->数据�?Data Source)->configure a new JDBC Data Source
2.
名称:MyData Source
JNDI名称:MyData Source
3.Continue->Continue->Create

�|�上�q�类文章特别�?此教�E�是本�h实践��保一个正常运行的一�?
1.安装MYSQL TOMCAT
2.copy mysql-connector-java-3.1.11-bin.jar to %TOMCAT_HOME%\common\lib
drop database if exists datasource;
create database datasource;
use datasource;
create table user(
username varchar(50) not null,
password varchar(50),
primary key (username)
);
insert into user(username,password) values("kingbill","10041207");--插入��试数据
3.使用Tomcat的web��理应用配置数据�?br />3.1 http://127.0.0.1:8080/admin/ enter username password
3.2 Resources->Data Sources->Data Source Actions->create New Data Source
3.3 JDBC Driver Class 不能随便�?Data Source URL可能是jdbc:mysql://IP:port
JNDI Name:MyDataSource
Data Source URL:jdbc:mysql://127.0.0.1:3306/datasource
JDBC Driver Class:org.gjt.mm.mysql.Driver
User Name:root
Password:123456
其余默认
Validation Query:可以不填
3.4 Save->Commit Change
4.�?TOMCAT_HOME%\conf\catalina\localhost\testapp.xml加入
��d��
如果发布�?TOMCAT_HOME%\conf\server.xml配置则在 ... 里面加入
----------------------------按照如上步骤不会出现以下错误
Cannot create JDBC driver of class '' for connect URL 'null'
Name MyDataSource is not bound in this Context
Cannot load JDBC driver class 'org.git.mm.mysql.Driver'
