Tomcat5.5.9 DBCP配置错误解决

Exception1:Cannot create JDBC driver of class "" for connect

解决:

1、<context>元素必须放在<host></host>之间.

2、自Tomcat5.5以后，<context>元素的<Resoucepram>元素取消,原参数元素都以Resouce的属性出现.

<Context path="" docBase="ROOT" debug="5" reloadable="true" crossContext="true">

<Resource name="jdbc/mysqltest" scope="Shareable" type="javax.sql.DataSource"

username="root" password="admin123" driverClassName="com.mysql.jdbc.Driver"

url="jdbc:mysql://localhost:3306/test" maxWait="3000" maxIdle="100" maxActive="10"/>

</Context>

Exception2:unable to get connection :no suitable driver

解决:

从eclipse中启动tomcat,发现启动时找不到org.apache.commons.dbcp.BasicDataSourceFactory,于是把Resouce元素中的factory="org.apache.commons.dbcp.BasicDataSourceFactory"删去，于是错误解决。
