配置TOMCAT连接池的问题
配置TOMCAT连接池时总是得不到连接,配置都没问题,JAR包也都放了,数据库是另一台机器,不知什么原因,JDBC也能连接通过.

[解决办法]
Connection refused: connect
是不是URl写的有问题啊
[解决办法]
conf/Catalina/localhost 目录下建立与你工程通明的****.xml
加入
<?xml version= "1.0 " encoding= "UTF-8 "?>
<Context>
<Resource
name= "jdbc/****** "
type= "javax.sql.DataSource "
password= "123456 "
driverClassName= "com.microsoft.jdbc.sqlserver.SQLServerDriver "
maxIdle= "2 "
maxWait= "5000 "
username= "sa "
url= "jdbc:microsoft:sqlserver://localhost;DatabaseName=quickstart "
maxActive= "4 "/>
5.5版本直接+就OK 6.0没有Catalina/localhost 自己建立后在加入

5.0版本的已经存在了哪个 同名XML只要加入
<ResourceLink global= "jdbc/***** " name= "jdbc/***** " type= "javax.sql.DataSourcer "/>
LZ可以揭贴了

你把你的配置文件发上来看看。
