我想配置Tomcat 7以使用RDS/MySQL实例，但我没有运气。我怀疑问题出在我的context.xml中。使用context.xml时，会发生不好的事情，例如不能通过Eclipse远程调试，因此无法调试我的DB代码发生了什么。我的context.xml（与喜欢的用户名/密码删除，以保护无辜的详细信息）：获取JNDI与RDS配合使用
<?xml version='1.0' encoding='utf-8'?>
<Context path="/puppy" reloadable="true" crossContext="true">
<Resource name="jdbc/myDB"
auth="Container"
type="javax.sql.DataSource"
username="username"
password="password"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://rds-instance:3306/myDB?autoReconnect=true"
validationQuery="select 1"
maxActive="10"
maxIdle="4"/>
</Context>
在部署应用程序，我得到了我的日志如下：

任何想法是怎么回事？人们不使用RDS使用JNDI吗？什么是最好的方法？
