我想配置Tomcat 7以使用RDS/MySQL實例，但我沒有運氣。我懷疑問題出在我的context.xml中。使用context.xml時，會發生不好的事情，例如不能通過Eclipse遠程調試，因此無法調試我的DB代碼發生了什麼。我的context.xml（與喜歡的用戶名/密碼刪除，以保護無辜的詳細信息）：獲取JNDI與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>
在部署應用程序，我得到了我的日誌如下：

任何想法是怎麼回事？人們不使用RDS使用JNDI嗎？什麼是最好的方法？
