tomcat配置多个数据库连接池

 关于TOMCAT配置多个连接池 

如果是TOMCAT5的话
META-INF下的context.xml
对这段进行修改
<Resource
       name="jdbc/aa"
       type="javax.sql.DataSource"
       driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
       password="123456"
       maxIdle="10"
       maxWait="-1"
       username="123"
       url="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=aa"
       maxActive="20"/>
添加在原来的后面就可以了,需要对参数进行适当的修改

如果是TOMCAT4的话
更改conf下server.xml

<Context path="/gdmail" reloadable="false" docBase="gdmail" >
