connecting my web Application to mysql

Hi,

I installed tomcat on my linode server,

and configured mysql

with a new DB : DBONE

and username/password : test/test

i configured my application in context.xml accordingly

source="org.eclipse.jst.jee.server:FillTrack">

maxActive="100" maxIdle="30" maxWait="10000" username="test"

password="test" driverClassName="com.mysql.jdbc.Driver"

url="jdbc:mysql://localhost:3306/DBONE" />

My application still can't connect to my DB, is there anything else i should do?

I set the tunnel from my desktop

and my local application can access the db , but the one hosted still can't. thx

Thank you for your help
